In this study, the dynamics of volatile compound alterations during the storage of ground roasted coffee in various packaging were investigated using solid-phase microextraction-gas chromatography-mass spectrometry. Each type of packaging underwent repeated opening and closing, simulating the gradual consumption behavior of the consumer who consumes ground coffee in smaller doses over time. The experimental results revealed that after 30 days of storage, 35 to 45% of the volatile substances originally present in the coffee were lost regardless of the type of packaging used. Notably, storing coffee in a paper sachet proved to be the least effective method, resulting in a loss of over 80% of all volatile coffee substances during this storage period.

Digital technologies are essential tools that enable traceability in supply chains. In low-income countries, traceability represents a challenge due to the complicated structure of supply chains and the involvement of multiple stakeholders. This research developed a framework for a digital traceability system (TS), using the Ethiopian coffee supply chain as a case study. A literature review was conducted to gain an in-depth understanding of state-of-the-art digital traceability technologies. A logistics audit was conducted to map the coffee supply chain in Ethiopia and evaluate the implementation level of traceability technologies. Although the implementation of traceability technologies in the Ethiopian coffee supply chain is low, the results revealed that the usage of traceability technologies improves downstream of the supply chain. The traceability framework developed in this study ranges from a paper-based TS to a fully digitalised TS. The implementation of a TS in the coffee supply chain of Ethiopia is met with several challenges such as affordability, limited awareness, resistance of certain stakeholders, infrastructure limitations, restricted accessibility of some technologies and insufficient policy frameworks. Stakeholders from low-income countries can use the framework developed in this study to adopt a TS for their supply chains in line with their needs and current digitalisation levels.

The coffee sector in Ethiopia is the livelihood of more than 20% of the population and accounts more than 25% of the country's foreign exchange earnings. Climate change is expected to affect the climatic suitability of coffee in Ethiopia, and this would have implications for global coffee output, the national economy, and farmers' livelihoods in Ethiopia. The objective of this paper is to assess the current and future impacts of climate change on bioclimatic suitability to C.arbica production in Ethiopia. Based on the current distribution of coffee production areas and climate change predictions from HadGEM2 and CCSM2 models and using the Maximum Entropy (MaxEnt) bioclimatic modeling approach, future changes in climatic suitability for C. arabica were predicted. Coffee production sites in Ethiopia were geo-referenced and used as input in the MAXENT model. The findings indicated that climate change will increase the suitable growing area for coffee by about 44.2% and 30.37% under HadGEM2 and CCSM2 models, respectively, by 2080 in Ethiopia. The study also revealed a westward and northwestward shift in the climatic suitability to C. arabica production in Ethiopia. This indicates that the suitability of some areas will continue with some adaptation practice, whilst others currently suitable will be unsuitable, yet others that are unsuitable will be suitable for arabica coffee production. These findings are intended to support stakeholders in the coffee sector in developing strategies for reducing the vulnerability of coffee production to climate change. Site-specific strategies should be developed to build a more climate resilient coffee livelihood in the changing climate. [ABSTRACT FROM AUTHOR]

The increasing complexity of deep learning models can make it difficult to interpret and fit models beyond a purely accuracy-focused evaluation. This is where interpretable and eXplainable Artificial Intelligence (XAI) come into play to facilitate an understanding of the inner workings of models. Consequently, alternatives have emerged, such as class activation mapping (CAM) techniques aimed at identifying regions of importance for an image classification model. However, the behavior of such models can be highly dependent on the type of architecture and the different variants of convolutional neural networks. Accordingly, this paper evaluates three Convolutional Neural Network (CNN) architectures (VGG16, ResNet50, ConvNext-T) against seven CAM models (GradCAM, XGradCAM, HiResCAM, LayerCAM, GradCAM++, GradCAMElementWise, and EigenCAM), indicating that the CAM maps obtained with ConvNext models show less variability among them, i.e., they are less dependent on the selected CAM approach. This study was performed on an image dataset for the classification of coffee leaf rust and evaluated using the RemOve And Debias (ROAD) metric. [ABSTRACT FROM AUTHOR]

Enterococcus faecalis is one of the bacteria that is commonly found in infected root canals, necrotic pulp and failure of root canal treatment, while Phorphyromonas gingivalis play a role in inducing periodontitis. Both bacteria can enter the blood circulation and lead to risk factors for systemic disease such as atherosclerosis. ChKM is the most widely used root canal sterilization, and also 0.2 % chlorhexidine mouthwash for long-term usage. It can destroy a potent cell and is allergenic. Developing an alternative material for root canal sterilization and mouthwash for plaque control is necessary. One of the alternative natural products that is predicted to have antibacterial effect is robusta coffee husk peels. This research aimed to investigate the antibacterial activity of robusta coffee (Coffea canephora) husk extract on E. faecalis and P. gingivalis. The robusta coffee husk was extracted using the maceration process with 96 % ethanol as the solvent. This research is an experimental laboratory, was tested by disk diffusion methods (Kirby-Baurer) using Gram-positive E. faecalis ATCC 29212 and Gram-negative P. gingivalis ATCC 33277 consisted of 6 groups: Aquadest as a negative control group, ChKM (for E.facecalis) and 0.2 % chlorhexidine (for P. gingivalis) as positive control, 4 treatment groups of coffee robusta husk extract with different concentrations there were 250, 250, 500, 750 and 1,000 mg/mL. The antibacterial effect was examined by measuring the clear zone around the disk paper. The results of this study proved the presence of antibacterial activity of coffee robusta husk extract against E. faecalis and P. gingivalis. The higher concentrations followed with a greater antibacterial effect. [ABSTRACT FROM AUTHOR]

Coffee is part of our daily lives since it is a drink with a symbolic value, both in our social relationships and as a stimulating drink. The main objective of this paper is to conduct a risk characterization of fluoride overexposure from the consumption of these beverages; for this purpose, in the present study, the fluoride concentration was determined in 80 samples of different brands of coffee commonly consumed in the Canary Islands, and the risk derived from their intake was then evaluated. Significant differences (p < 0.05) were found between the coffee brands soluble Nescafé Classic®, Saimaza®, Auchan®, Tirma® soft blend, and Hacendado® and the other analyzed brands. The brand that recorded the highest mean fluoride levels is "Hacendado descafeinado®" (0.308 mg/L). The problem with coffee is not the fluoride it contains but the fact that, according to the survey results, most coffee drinkers brew their coffee with tap water (over 51% of respondents use tap water). The results of the fluoride content in coffee prepared with tap water from the different areas of Tenerife in the Canary Islands (metropolitan, northern, and southern areas) have reported higher concentrations of fluoride: north (max. concentration found of 16.68 mg/L), south (max. concentration found of 8.47 mg/L) and metropolitan (max. concentration found of 4.73 mg/L). Coffee has not been identified as a risk of dietary overexposure to fluoride; however, the use of tap water for its brewing has been identified as a factor that considerably increases its concentration. Therefore, the use of bottled water is recommended, especially in regions such as the Canary Islands, which have high concentrations of fluoride in their water. [ABSTRACT FROM AUTHOR]

Caffeic acid is a common phenolic acid found in coffee and numerous fruits and vegetables. Known for its antioxidant properties, it is widely used as a dietary supplement as part of a polyphenol mixture or as an extract in the form of a capsule or powder. It is also available in liquid form as a homeopathic supplement. Caffeic acid phenethyl ester (CAPE) is an active component of propolis produced by honey bees. Propolis extract is used as a supplement and is available in various forms. The present paper is a comprehensive review of the biomedical literature, showing that caffeic acid effects are hormetic and occur in numerous biological models and cell types for a broad range of endpoints including many aging-related processes. Hormesis is a biphasic dose/concentration response displaying a low concentration/dose stimulation and a high concentration/dose inhibition. Complex alternative search strategies for caffeic acid were used since publications rarely used the terms hormesis or hormetic. Evaluation of the data provides the first assessment of caffeic acid-induced hormetic concentration/dose responses and their quantitative features. Their mechanistic foundations, extrapolative strengths/limitations, and their biomedical, clinical, and public health implications are discussed. Suggestions for future research are presented.

Coffee is an important crop with economic and social importance in several countries. With a daily consumption estimated at 2.2 billion cups, its sustainability is facing critical challenges given the projected climate changes. Coffea arabica, which represents ∼60% of the global market coffee is a delicate crop, quite susceptible to diseases and biotic stresses. Developing climate‐resilience cultivars is necessary, and it includes coffee plants adapted to new farming conditions that can meet the demand for biotic and abiotic tolerance and quality. In this context, Coffea canephora emerges as a potential candidate if the crop combines plasticity and cupping quality. Plant plasticity refers to adjusted phenotypic performance when grown in different environments, a fact that may help mitigate the detrimental effect of climate changes. In this study, using a multiple environment trial, we combined genomic and genotype‐by‐environment analyses to answer the following main question: How the climate effects may affect the phenotypic plasticity in C. canephora? Our contributions in this paper are fourfold: (i) we draw attention to the cupping quality and yield performance of C. canephora cultivars when evaluated in high‐altitude and cold weather, (ii) we compared C. arabica and C. canephora phenotypic plasticity and highlight genotypes with broad and specific adaptation to certain environmental conditions, and finally, (iii) using stochastic simulation, we emphasize the potential of molecular breeding in the long term in coffee. Altogether, we present an emerging view on how C. canephora could be a valid alternative for climate‐smart cultivars in a projected scenario of altered climatic conditions. Core Ideas: Coffee sustainability is facing critical challenges given the projected climate changes.Inference on plant plasticity can identify plants more subjected to genotype‐by‐environment interaction, and therefore mitigate the detrimental effect of rapidly changing climate.Analyses of Coffea canephora phenotypic plasticity highlighted genotypes with broad and specific adaptation to certain environmental conditions.Results shed new light on the use of C. canephora as an alternative for climate‐smart coffee cultivars.

This paper studies the history of contractual choice in coffee plantations of São Paulo, Brazil. It focuses on the consolidation of non‐captive labour markets in the early phases of the transition from slavery in the country, particularly in the 1840s–50s. Vis‐à‐vis the alternatives of fixed rents and fixed payments per time worked or piece rates, the paper examines the rationale for the adoption of sharecropping arrangements with European bonded labourers. New archival evidence suggests that sharecropping had no obvious productivity advantage over alternative labour–rental arrangements in this period, and that the adoption of sharecropping arrangements resulted from the positional advantage of its first proposers, who influenced later choices of contractual design. A credit‐labour tie‐up long outlived the original sharecropping arrangements, in turn allowing for the immigration of poor and credit‐constrained Europeans, paving the way to insert Brazil into the circuits of mass migration without promoting institutional reforms to attract non‐bonded immigrants.

Coffee is not merely a refreshing beverage but also invigorates people, provides relaxation, contributes to human health, and fosters closer social connections. Coffee is one of the most widely consumed beverages worldwide and the most traded commercial commodity. Moreover, the rapid development of the Vietnamese coffee industry caused some concerns due to its insufficient performance and the fierce competition within the industry. It is significant to establish an efficient supply network; notwithstanding, supplier selection has always been a challenge for companies. Therefore, this paper employs a hybrid model to determine the supplier selection criteria, a vital factor for a manufacturer under practical operating conditions. Firstly, a combined model of Grey forecasting and the Grey Fourier series is applied to forecast future rainfall and temperature data for six consecutive years. Secondly, based on the criteria, strategies, and buyer requirements, the single-objective linear programming model helps identify the outperformed suppliers. The results found that prices and location change are determinants of supplier selection, and supplier shortage is an enormous barrier for the industry. In this study, these price forecasts allow supply chain management to make informed decisions about inventory levels, transportation routes, and resource allocation to ensure smooth operation and optimize coffee supply chain management.

Several pests affect coffee (Coffea spp. Rubiaceae) and macadamia, Macadamia integrifolia Maiden & Betche (Proteaceae) in Hawaii. The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), is the most damaging to coffee, while the tropical nut borer, Hypothenemus obscurus (Fabricius) (Coleoptera: Curculionidae: Scolytinae), is one of the worst pests of macadamia. This paper investigates the potential efficacy of a long-lasting insecticide-incorporated net (LLIN) under laboratory conditions to manage these pests. The LLIN (40 denier with mesh size 625 knots/in²), incorporated with α-cypermethrin (0.34%), was excised into 100 mm circles and inserted in 100 mm Petri dishes. Nets with the same quality but without insecticides were used as control treatments. Twenty beetles (H. obscurus or H. hampei) each were placed on the treated and non-treated netting at 4 treatment or exposure hours—1, 6, 12, and 24—with 5 replicates. Subsequently, the beetles were ranked alive, affected, or dead. The results showed that the LLIN with α-cypermethrin had significant lethal and sub-lethal effects on both Hypothenemus species, causing over 90% mortality after 24 h of exposure and paralysis after 1, 6, and 12 h of exposure. The highest lethality value was recorded after 24 h of exposure for both H. obscurus and H. hampei. The LT50 of H. obscurus and H. hampei was 18.78 min and 2.15 h, respectively, while the LT90 values were 32.11 and 20.67 h. These results imply the potential effectiveness of LLINs with α-cypermethrin for management of H. obscurus and H. hampei , but field studies are warranted for optimization. [ABSTRACT FROM AUTHOR]

Coffee is one of the most consumed products worldwide. Among the varieties of this product, specialty coffee is a type of coffee that has been growing in the world market. This paper aims to assess the effects that the conditions derived from coffee roasting at different altitude levels have on the quality of the product. It was discovered that processing coffee at a higher altitude level yielded a smaller increase in bitterness. This led to a better Specialty Coffee Association (SCA) score in cupping and, consequently, to better preservation of the coffee quality. The storage time affected the aroma by associating roaster aromas with older coffees. Although the assessed origins had the same NIR spectra, differences in peak intensity lead to variations in the flavor and aroma of the coffee. Furthermore, although green beans prolong quality allowing a SCA score of 84.73 ± 2.81 after 4 months of storage, roasted coffee at higher altitudes could also maintain the quality between production and consumption (SCA score of 80.22 ± 0.91 after 2 months). Finally, this research found that the instrumental equipment helped to find minor changes in the sensorial profile, and with these changes correlated with the sensorial panel, the best conditions to preserve coffee quality were found.

Geographical scholarship has advocated the importance of endogenous and place-sensitive development to levelling up left-behind places, by means of reactivating untapped potentials and recuperating a sense of belonging. Drawing on the approaches of global value chain (GVC), and to a lesser extent, global production network (GPN), this paper rethinks how GVC/GPN participation articulates with endogenous assets and enhances local actors' capacities to achieve economic and social upgrading. We present a case study of the coffee economy in Lujiang Township, Yunnan Province, China. We find that local villagers are able to tap into opportunities of learning and upgrading, but these processes are mediated by institutions and moral economies. Ultimately, economic empowerment translates into the revival of a sense of belonging. [ABSTRACT FROM AUTHOR]

The aim of the present study was to estimate risk factors for type 2 diabetes in women. A case–control study included 99 newly diagnosed cases of type 2 diabetes and 198 controls. Descriptive statistics were used, and conditional univariate logistic regression analysis was used to determine differences between cases and controls. According to multivariate analysis-independent risk factors for T2DM were as follows: oral contraceptives (OR = 2.57; 95% CI = 0.99–6.62), and their longer duration of use (OR = 3.55; 95% CI = 1.79–6.99); greater quantity of coffee consumed (OR = 1.89; 95% CI = 1.06–3.39), occupation (odds ratio – OR = 3.17; 95% confidence interval – CI = 1.57–6.41); never been pregnant (OR = 5.88; 95% CI = 2.23–15.49); family history of diabetes (OR = 18.52; 95% CI = 7.25–47.62); overweight and obesity (OR = 2.13, 95% CI = 1.39–4.53); stress (OR = 4.42; 95% CI = 2.19–8.26), and the greater number of stressful life event (OR = 1.65; 95% CI = 1.22–2.23). The present study emphasizes the role of oral contraceptive use, a greater quantity of coffee consumed, occupation, never been pregnant, overweight and obesity, major stressful life events, and family history of diabetes in the development of type 2 diabetes. What is already known about this topic (1) It is well known that lifestyle factors and genetics are involved in the development of type 2 diabetes mellitus (T2DM) and its complications. (2) Gender differences in T2DM are explained by differences in sex chromosomes, sex hormones, possible hormonal disbalance, lifestyle habits in nutrition, and physical activity. (3) The global prevalence of diabetes will increase to 366 million by 2030, even if the prevalence of obesity remains constant. (4) The vast majority of patients with diabetes have T2DM. (5) Knowledge of modifiable and non-modifiable risk factors for T2DM is important for the prevention of this disease. (6) Many factors have been investigated for their relation to T2DM, but data on the association between some of them and the risk for diabetes are not consistent. What this paper adds (1) Independent predictive factors for T2DM in women are oral contraceptive use and quantity of coffee consumption. (2) Other independent predictive factors for T2DM include occupation, never been pregnant, overweight and obesity, major stressful life events, and family history of T2DM. (3) A greater number of children was significantly negatively related to T2DM. (4) In this study, oral contraceptive use and especially their use for 5 years and more were significantly positively associated with T2DM after adjustment for potential confounding factors. (5) This study highlights, in particular, the need to target overweight and obese women who use oral contraceptives, have never been pregnant, and consume a greater quantity of coffee, with major stressful life events and a family history of diabetes. These groups are more vulnerable to T2DM; thus, prevention should focus on these groups. [ABSTRACT FROM AUTHOR]

Type 2 diabetes (T2D) is a growing health concern with an estimated 462 million people having been diagnosed worldwide. T2D is characterized by chronically elevated blood glucose and insulin resistance, which culminate in a diminished function of the β-cell mass in its later stages. This can be perpetuated by and result in inflammation, excess reactive oxygen species production, obesity, and the dysregulation of multiple cellular pathways. Many naturally occurring small molecules have been investigated in terms of their roles in modulating glucose homeostasis and β-cell function. Many of these compounds can be found in commonly used sources of food and drink. Interestingly, a correlation has been observed between coffee consumption and T2D incidence. However, the specific compounds responsible for this correlation and their mechanisms are still somewhat undetermined. This paper reviews recent research findings on the effects of several polyphenols that are either found in coffee or are metabolites of compounds found in coffee (enterodiol, enterolactone, matairesinol, secoisolariciresinol, kaempferol, quercetin, and chlorogenic acid) on glucose homeostasis and health complications associated with glucose dysregulation, with a special emphasis on their potential anti-diabetic effects. The factors that affect polyphenol content in coffee are also addressed. [ABSTRACT FROM AUTHOR]

This review provides a practical and comprehensive overview of non-pharmacological interventions for metabolic-associated fatty liver disease (MASLD), focusing on dietary and exercise strategies. It highlights the effectiveness of coffee consumption, intermittent fasting, and Mediterranean and ketogenic diets in improving metabolic and liver health. The review emphasizes the importance of combining aerobic and resistance training as a critical approach to reducing liver fat and increasing insulin sensitivity. Additionally, it discusses the synergy between diet and exercise in enhancing liver parameters and the role of gut microbiota in MASLD. The paper underscores the need for a holistic, individualized approach, integrating diet, exercise, gut health, and patient motivation. It also highlights the long-term benefits and minimal risks of lifestyle interventions compared to the side effects of pharmacological and surgical options. The review calls for personalized treatment strategies, continuous patient education, and further research to optimize therapeutic outcomes in MASLD management. [ABSTRACT FROM AUTHOR]

This study attempts to investigate Jordanian oaths from a sociocultural and translational perspective. The study shows that Jordanian oaths are insufficiently explored from such a perspective. The paper uncovers that Jordanian oaths have many formulas and are taken in many social and cultural aspects such as religion, body parts, honor, headdress, curse, and Arabic coffee, among many other things. In order to conduct the study, examples resembling these different aspects of oaths are suggested, and some social and cultural details are given before the examples. To make the Jordanian oaths clear, each oath example is contextualized in a social and cultural setting and then followed by a literal translation. Finally, the examples are analyzed and discussed, translationally, socially, and culturally in order to give a ground evidence that Jordanian oaths are difficult to translate from Arabic into English.

Coffee, one of the top ten most globally traded commodities, can be grown in different agricultural regions presenting peculiar characteristics. Thus, the determination of inorganic nutrients in ground-roasted coffee has nutritional relevance and allows authentication as well as tracking of the origin of the product. Analytical methods routinely used to determine inorganic nutrients in food are based on time-consuming steps that involve acid digestion followed by elemental quantification. In this study, analytical strategies for the direct determination of inorganic macronutrients (P, K, Ca, and Mg) in commercial samples of ground-roasted coffee were evaluated by portable X-ray fluorescence spectrometry (pXRF) using two commercial spectrometers. Two calibration approaches were tested: (i) using plant-based certified reference materials (CRMs); (ii) matrix-matched calibration, using samples of ground-roasted coffee as well as the corresponding solid residues resulting from infusion, the spent coffee grounds (SCG). The analyte mass fractions in these samples were determined by the reference method (decomposition using HNO3 and H2O2 followed by ICP OES measurements). In the latter method, calibration models were built using reference values and analytical signals obtained by pXRF. Pressed pellets from the samples (CRMs, ground-roasted coffee, and SCG) were prepared. The samples were irradiated for 50 s using both spectrometers under two experimental conditions: X-ray tube voltage of 15 kV and 50 kV. Calibration models with excellent linearity were obtained (r ≥ 0.90) for all analytes. The proposed matrix-matched calibration method was considered the most accurate approach for elemental determination (mainly P and K) in samples of ground-roasted coffee as well as in the spent coffee grounds, an alternative agricultural fertilizer.

Background: Multiple sclerosis (MS) is a demyelinating disease of the central nervous system. Caffeine, as the most widely consumed psychoactive substance, has been suggested to have potential effects on the clinical course and disability levels of MS patients. This study aimed to review the current evidence on the effects of coffee/caffeine in patients with MS. Methods: This study followed the Joanna Briggs Institute (JBI) Manual for Evidence Synthesis and PRISMA 2020 statement. Clinical evidence regarding the effects of caffeine/coffee in MS patients was considered. A systematic search was performed in PubMed, Scopus, Web of Science, and Embase in October 2023, and updated via handsearching in March 2024. JBI's critical appraisal tools were utilized to scrutinize the risk of bias. Results: Out of 297 screened records, eight studies were eventually found to meet our inclusion criteria. The sample size of the studies varied between 12 and 1372 and the study designs were retrospective cohort, RCT, single-blind crossover trial, single-arm pilot study (each one study), and cross-sectional (four studies). No significant association between the level of disability and coffee/caffeine intake has been reported, although it was reported to be associated with cognitive improvements. Discussion: Evidence indicates an association between coffee/caffeine consumption, and improved cognitive outcomes in patients with MS, while there is no considerable relationship with the disease disability. Considering the limitations of the evidence, such as the small number of studies, and great diversity in study designs, the findings of this study should translate to clinical practice with caution.

Introduction: Breeding programs have developed high-yielding Coffea arabica F1-hybrids as an adaptation against adverse conditions associated with climate change. However, theresponse to drought of coffee F1 hybrids has seldom been assessed. Methods: A trial was established with five C. arabica genotypes (2 pure lines: Catimor and Marsellesa and 3 F1 hybrids: Starmaya, Centroamericano and Mundo Maya) planted under the leguminous tree species Leuceana leucocephala. Coffee growth, yield and physiological responses were assessed under a rain-fed (control: CON) and a rainfall reduction treatment (RR) for 2 years. Results: The RR treatment created a long-term rainfall deficit in a region with suboptimal temperature similar to those predicted by climate change scenarios. Moreover, the RR treatment reduced soil water content by 14% over 2 successive years of production and increased hydric stress of the three F1-hybrids (leaf water potentials averaged -0.8 MPa under RR compared with -0.4 MPa under CON). Under RR, coffee yields were reduced from 16 to 75% compared to CON. Mundo Maya F1 hybrid was the sole high-yielding genotype apable of sustaining its yield under RR conditions. Our results suggested that its significant increase in fine root density (CON = 300 and RR = 910 root.m-2) and its maintenance of photosynthetic rate (2.5 - 3.5 mmol CO2 m-2 s-1) at high evaporative demand might explain why this genotype maintained high yield under RR condition. Discussion: This work highlights a possible drought tolerance mechanism in fruit bearing adult coffee trees where the plant fine root number increases to intake more water in order to preserve turgor and sustainphotosynthesis at high ETo and therefore conserves high yield in dry conditions.

Accurate coffee plant counting is a crucial metric for yield estimation and a key component of precision agriculture. While multispectral UAV technology provides more accurate crop growth data, the varying spectral characteristics of coffee plants across different phenological stages complicate automatic plant counting. This study compared the performance of mainstream YOLO models for coffee detection and segmentation, identifying YOLOv9 as the best-performing model, with it achieving high precision in both detection (P = 89.3%, mAP50 = 94.6%) and segmentation performance (P = 88.9%, mAP50 = 94.8%). Furthermore, we studied various spectral combinations from UAV data and found that RGB was most effective during the flowering stage, while RGN (Red, Green, Near-infrared) was more suitable for non-flowering periods. Based on these findings, we proposed an innovative dual-channel non-maximum suppression method (dual-channel NMS), which merges YOLOv9 detection results from both RGB and RGN data, leveraging the strengths of each spectral combination to enhance detection accuracy and achieving a final counting accuracy of 98.4%. This study highlights the importance of integrating UAV multispectral technology with deep learning for coffee detection and offers new insights for the implementation of precision agriculture.

Known for its stimulating effects on the nervous and cardiovascular systems, caffeine has proven remarkable versatile properties. It can be used in a wide range of different products, from anti-aging cosmetics to the pharmaceutical treatment of hair loss. Caffeine is known for its antioxidant properties and is commonly found in moisturising creams recommended as anti-aging or anti-cellulite and also for the treatment of different skin disorders, including androgenic alopecia. This bioactive is also described to be able to enhance the sunscreen scattering effect of well-known ultraviolet (UV) blockers. One of the major challenges remains its penetration capacity into deeper skin layers, which may be achieved by the use of nanosized delivery systems, yet without the risk of transdermal delivery. In this review, we discuss the nutraceutical value of caffeine in cosmetic products, so-called nutricosmetics, which grants this bioactive several advantages in several formulations, in comparison to other potential bioactives of nutricosmetic value. Furthermore, the disclosed effects of bioactives commonly found in coffee, tea, and their by-products are reviewed and discussed. The discussion concludes by highlighting the significant benefits of caffeine in the treatment of skin disorders and its potential to enhance and promote skin health. [ABSTRACT FROM AUTHOR]

Purpose: This study aims to find out how pomposia fruit powder (Syzygium cumini L.) mixed with roasted coffee (RCO) affected antioxidants, phytochemicals, lipid peroxidation inhibition and sensory attributes. Design/methodology/approach: Pomposia fruits (Syzygium cumini L.) powder (PFP) was integrated with RCO at levels of 0.0%, 5.0%, 10.0%, 15.0% and 20.0%. RCO, PFP and binary mixtures containing RCO: PFP were evaluated for their total phenolics (TP), total flavonoids (TF), anthocyanin content (AC), antioxidant activity and phenolic compounds fractionation. The oxidative indices of coffee oil samples were measured throughout different storage intervals. Additionally, sensory characteristics of RCO enriched with different PFP doses were evaluated. Findings: PFP samples exhibited the greatest TP content (1910 mg/100 g), whereas RCO samples had the lowest concentration (1090 mg/100 g). As more PFP was added, the corresponding coffee blends' concentrations of TP, TF and AC were improved significantly. PFP possesses a radical-scavenging activity that is about 1.20 times more than RCO's. DPPH (2,2-diphenyl-1-picrylhydrazyl) radical-scavenging activity jumped significantly from 74.13% in control (untreated) samples to 77.64%, 78.39% and 80.15% for samples enriched with 10.0%, 15.0% and 20% PFP, respectively. Significant increases in gallic acid, hesperidine, benzoic acid, chlorogenic acid, hispertin, catechol, quercetin, pyrogallol and rutin were detected when RCO was mixed with different quantities of PFP. At the end of storage trial, the coffee oil treated with 20% PFP had AV, PV and TBA values that were about 1.70, 1.95 and 1.66 times lower, respectively, than those of the control sample that had not had PFP addition. The RCO with 5.0% PFP achieved the greatest over acceptability grades. Originality/value: To the best of the authors' knowledge, this study was the first study to evaluate the effect of incorporating various level of pomposia fruit powder into RCO. The findings shows that adding different concentrations of pomposia fruit powder into RCO can indeed enhance the radical-scavenging activity of the coffee and potentially extend its shelf life.

Background: Coffee consumption is inversely associated with type 2 diabetes. Cafestol, a bioactive compound in coffee, has demonstrated glucose-lowering and insulin-secretory properties in cell and animal studies. The acute effects of cafestol on glucose metabolism in humans have only been briefly investigated, and longer-term effects have not been explored. This study aimed to assess the effects of purified cafestol on insulin sensitivity and other metabolic parameters in healthy individuals with increased waist circumference at risk of developing type 2 diabetes. Methods: A 12-week randomized, placebo-controlled, parallel trial was conducted with 40 participants. Insulin suppression tests, mixed meal tests, and MRI scans were performed before and after the intervention. Results: Administering 6 mg of cafestol twice daily did not alter insulin sensitivity or glucose tolerance but led to significant reductions in body weight (2%), visceral fat volume (5%), and gamma-glutamyl transferase levels (15%) compared to the placebo. Conclusions: Cafestol may hold promise for weight and visceral fat reduction. Cafestol did not improve insulin sensitivity or glucose tolerance in this study but might still contribute to the observed inverse association between coffee consumption and type 2 diabetes. Future research should explore higher dosages and longer treatment durations, particularly in individuals with impaired glucose metabolism and type 2 diabetes. [ABSTRACT FROM AUTHOR]

Background: Coffee is widely consumed around the world. In Japan, it is a type of "Shikohin" (consumed for flavor, not nutrition). Several medical studies have reported the beneficial effects of coffee consumption, whereas others suggest that these beneficial effects on psychological aspects are marginal. The habit of consuming large amounts of caffeine through coffee may improve short-term resilience in stressful situations and may exhaust individuals in the long term. We hypothesized that people who habitually drink high amounts of coffee would have lower resilience scores and higher acute stress responses. Methods: Adult Japanese men completed a questionnaire that included a resilience scale and Shikohin consumption habits. Experimental participants were recruited from the survey respondents and classified into three groups based on their coffee consumption per day: No Coffee, Low Coffee, and High Coffee. All participants were asked to join the Trier Social Stress Test-Online (TSST-OL). Subjective stress and salivary cortisol concentrations was measured at eight time points during the experiment. There were 16 participants in each group for the analysis (mean age = 46.10 years, SD = 12.58). Results: Statistical analysis showed that both subjective stress and salivary cortisol concentrations significantly increased following TSST-OL exposure. However, there were no significant differences among the groups, and the hypotheses were not supported. Conclusions: This study demonstrated the effectiveness and stability of the TSST-OL. Additionally, coffee consumption habits were not significantly related to resilience scale scores or acute stress responses. [ABSTRACT FROM AUTHOR]

Background: Breast cancer is the most diagnosed cancer in women. Its pathogenesis includes several pathways in cancer proliferation, apoptosis, and metastasis. Some clinical data have indicated the association between coffee consumption and decreased cancer risk. However, little data is available on the effect of coffee on breast cancer cells in vitro and in vivo. Methods: In our study, we assessed the effect of Turkish coffee and Fridamycin-H on different pathways in breast cancer, including apoptosis, proliferation, and oxidative stress. A human breast cancer cell line (MCF-7) was treated for 48 h with either coffee extract (5% or 10 v/v) or Fridamycin-H (10 ng/ml). Ehrlich solid tumors were induced in mice for in vivo modeling of breast cancer. Mice with Ehrlich solid tumors were treated orally with coffee extract in drinking water at a final concentration (v/v) of either 3%, 5%, or 10% daily for 21 days. Protein expression levels of Caspase-8 were determined in both in vitro and in vivo models using ELISA assay. Moreover, P-glycoprotein and peroxisome proliferator-activated receptor gamma (PPAR-γ) protein expression levels were analyzed in the in vitro model. β-catenin protein expression was analyzed in tumor sections using immunohistochemical analysis. In addition, malondialdehyde (MDA) serum levels were analyzed using colorimetry. Results: Both coffee extract and Fridamycin-H significantly increased Caspase-8, P-glycoprotein, and PPAR-γ protein levels in MCF-7 cells. Consistently, all doses of in vivo coffee treatment induced a significant increase in Caspase-8 and necrotic zones and a significant decrease in β- catenin, MDA, tumor volume, tumor weight, and viable tumor cell density. Conclusion: These findings suggest that coffee extract and Fridamycin-H warrant further exploration as potential therapies for breast cancer. [ABSTRACT FROM AUTHOR]

Background: Nonrestorative sleep (NRS) is related to numerous adverse outcomes. There is rare evidence of its associated factors, especially in Chinese adolescents. This study aimed to explore the factors associated with NRS in Chinese adolescents and the potential moderation effects of coffee or tea consumption. Methods: This cross-sectional study invited adolescents attending Grades 7–11 in Nanjing, China, to complete a self-administered questionnaire, including their NRS, stress, anxiety, physical symptoms, depression, sociodemographics, and lifestyles. Linear regressions were applied to investigate the associated factors of their NRS, with the moderation effects of coffee or tea consumption and other characteristics being tested by additionally including their interactions. Results: Totally 481 adolescents (49% male, age 15.5 ± 1.5 years) were enrolled, with the average global NRS score of 42.16 ± 7.57. Higher family income (β = 2.01, P = 0.007), longer sleep duration (β = 2.33, P = 0.011), and moderate after-class activity (β = 1.50, P = 0.044) contributed less NRS, while higher educational level (β = −2.60, P = 0.033), more coffee or tea consumption (β = −1.68, P = 0.013), physical symptoms (β = −3.85, P < 0.001), stress (β = −0.23, P = 0.005), anxiety (β = −1.54, P = 0.045), and depression (β = −0.13, P = 0.014) contributed more NRS. Females (β = 0.82, P = 0.005), older age (β = −0.46, P = 0.029), and higher education level (β = −1.68, P < 0.001) contributed less refreshment from sleep, more physical/medical symptoms of NRS, and less daytime function, respectively. Coffee or tea consumption moderated the associations of somatic symptoms (β = 0.25, P = 0.021), stress (β = 0.29, P = 0.022), anxiety (β = 0.27, P = 0.005), and depression (β = 0.17, P = 0.021) with NRS. Conclusions: Longer sleep duration, moderate after-class activity, reduced coffee or tea consumption, and promotion of physical and mental health may help reduce adolescents' NRS. Coffee or tea consumption may help buffer the negative associations of somatic symptoms, stress, anxiety, and depression with NRS. [ABSTRACT FROM AUTHOR]

The coffee sector's challenges, such as low and volatile prices, prompt adopting strategies focused on product differentiation, including high-quality specialty coffee. Nevertheless, documented evidence shows that small producers in Oaxaca, Mexico, are not equally benefiting from this market opportunity compared to other states in Mexico, such as Veracruz or Chiapas. This review article identifies and analyzes the factors in integrating small Oaxacan producers into the specialty market. A total of 138 scientific contributions were analyzed, emphasizing three thematic axes: (1) Trends and behavior of the coffee market. (2) Factors to enable the production of high-quality coffee, and (3) Current situation and challenges of small coffee producers in the specialized market. We found that coffee quality depends on the environment (mainly altitude, temperature, and geographical conditions) and agronomic, genetic, and socioeconomic factors. Moreover, agronomic and genetic factors should focus on choosing coffee varieties suited to the environmental conditions of the farm and adopting innovations in production, harvest, and post-harvest processes. The most significant socio-economic factors that hinder small coffee producers' participation in the specialized market include but are not limited to, lack of information, social connection, and financial resources. However, in the literature analyzed here, it was also possible to identify specific farmworker experiences that operate with a community approach and have inserted their small producers into high-quality market transactions. For this reason, this article suggests that the standardization model of quality from the collective approach within the community-based enterprise is a sustainable and inclusive alternative to achieve the goal: the insertion of small Oaxacan coffee producers into the more significant specialty market.

Background: While coffee and green tea have been suggested to have immunoprotective effects, it remains elusive whether they can decrease the risk of coronavirus disease 2019 (COVID-19). Objective: We prospectively examined the associations of coffee and green tea consumption with the risk of COVID-19 among mRNA vaccine recipients during the epidemic of the Omicron variant. Methods: Participants were 2,110 staff (aged 18 to 76 years) of a large medical facility in Tokyo, who attended a serosurvey in June 2022, predominantly received =3 doses of vaccine, and were followed for COVID-19 until December 2022. Coffee and green tea consumption was ascertained via a questionnaire. COVID-19 was identified through the in-house registry. Cox proportional hazards model was used to estimate the hazard ratios (HRs) of COVID-19 across the categories of beverage consumption. Results: During 6 months of follow-up, 225 (10.6%) cases of COVID-19 were identified. Contrary to the expectation, higher consumption of coffee was associated with a significant increase in the risk of COVID-19; multivariable-adjusted HRs were 1.00 (reference), 0.92 (95% confidence interval [CI], 0.62-1.35), 1.48 (95% CI, 0.99-2.22), and 1.82 (95% CI, 1.20-2.76) for <1 cup/day, 1 cup/day, 2 cups/day, and =3 cups/day, respectively (P trend = 0.003). Green tea consumption was not significantly associated with the risk of COVID-19. The association with coffee was attenuated if serologically detected infection was added to the cases. Conclusion: In a cohort of Japanese hospital staff who received COVID-19 vaccine, higher consumption of coffee was associated with an increased risk of COVID-19 during the epidemic of the Omicron variant. There was no evidence of a significant association between green tea consumption and COVID-19 risk. [ABSTRACT FROM AUTHOR]

Bondowoso Robusta Coffee is a type of Robusta coffee that has a distinctive taste and high quality. The distinctive taste and high quality are obtained from the results of harvest management and post-harvest processing in accordance with Standard Operating Procedures (SOP). This research will be carried out by testing the characteristics of Robusta ground coffee with a mixture of palm sugar and vanilla flavoring to improve the quality of Robusta ground coffee. This was done by knowing the physicochemical and organoleptic properties of the mixed Robusta ground coffee. The aim of this research is to determine the interaction between roasting level and the composition of palm sugar and vanilla powder on the physiochemical and organoleptic properties of 3 in 1 Robusta Coffee. This research uses an experimental plan arranged factorially with the basic pattern of a Completely Randomized Design (CRD) with 4 replications. This design has two factors, the first factor is the roasting level and the second is the mixture composition. The results of this research show (1) The interaction of Roasting Level and Mixture (palm sugar and vanilla powder) has no significant effect on all observed variables such as water content, Brix content, pH value, and powder bulk density. (2) The effect of the main level of roasting has a very significant effect on the observed variables of rainfall density and an insignificant effect on the variables of air content, Brix content and pH value. (3) The effect of the main mixture has a very significant effect on the observed variables of air content, Brix content and powder bulk density and has no significant effect on the variable pH value.

Coffee quality and varieties matter for its ultimate flavor. As multiple factors influence taste during coffee production, hyperspectral imaging (HSI) stands out with great potential for quality assessment, defect supervision, and character identification. With a relatively comprehensive summary of current HSI-based research in coffee, this literature review critically reveals HSI's competence and present shortcomings in practical applications within the coffee industry. Sequentially, potential applications of HSI technology in coffee component analysis and flavor estimation, blemish diagnosis, and origins or attributes identification are illustrated. Finally, several key challenges and future perspectives of HSI are indicated from a practical and sustainable perspective, with digitalization as a major goal in the coffee industry.

Coffee is one of the three most consumed beverages in the world. It is made by first roasting coffee beans, and then grinding and boiling or steeping the roasted beans in water (brewing). The process of roasting and brewing produces a complex mix of bioactive compounds, including methylxanthines (caffeine, theobromine, theophylline), diterpenes, chlorogenic acid, trigonelline, flavonoids, and hydroxycinnamic acid. In the body, these compounds may be metabolized to produce other bioactive compounds. For example, caffeine is primarily (80%) broken down by demethylation to produce paraxanthine. In the post-ingestion period, levels of paraxanthine may be higher than caffeine due to its slower elimination. Hence, while paraxanthine is not found in coffee itself, it has many of the same properties as caffeine and may be a major contributor to its metabolic effects. The impacts of caffeine and paraxanthine on metabolism relate to their impact on adenosine receptors (notably the A2A receptor). It has been known for almost 100 years that intake of coffee stimulates metabolism by between 5% and 20% for at least 3 h. About half of the increase in metabolic rate after drinking coffee is due to caffeine and derivatives, but the source of the other half is unclear. There are large differences in the response to the same amount of coffee in different individuals, which may be related to caffeine clearance rates, effects of other unknown pathways, genetic polymorphism, age, sex, and body composition.

This study evaluated consumers' perceptions of beverages obtained from the intervarietal hybrids of Coffea canephora, Conilon and Robusta, produced in the Western Amazon, through a home-use test with 127 participants. An acceptance test and a Check-All-That-Apply procedure were applied. Two clones, BRS 2314 and BRS 2357, were studied (both in natural and fermented versions) and their roasted coffee composition was also evaluated. All beverages were described as having a mild aroma, roasted flavor, and slightly sour taste; consumers noticed both the effect of the fermentation process and genetics. Natural coffees had greater sensory acceptance than fermented ones. Natural coffees were most associated with a slightly bitter taste, and were well accepted by almost half of the participants, mainly women. Fermented coffees were both associated with fermented flavor, but also presented specific characteristics. BRS 2314F was most associated with a fruity flavor and slightly bitter taste and was well accepted by younger consumers with higher levels of education. BRS 2357F was most associated with tobacco flavor and bitter taste and was well accepted by older consumers with a lower education level and a higher coffee consumption frequency. The positive acceptance of C. canephora intervarietal hybrid beverages allowed us to confirm its material market potential. [ABSTRACT FROM AUTHOR]

After waiting in a long line for your favourite cup of coffee, you finally sit down with your mug and find that the coffee is still scalding hot! How long do you need to wait before you can enjoy it? Once it cools enough, how much time do you have to enjoy it? Are there ways to speed up the process? These questions motivate the presented modelling scenario about tracking the temperature of a cup of coffee as it cools. Students are put in the role of an inquisitive coffee enthusiast who does their due diligence in preventing burns and carefully experimenting on their coffee so that they, and others to come, can enjoy that perfect cup. They identify their assumptions and interventions before developing model differential equations for each case, which force discontinuities on the derivative and even on the solution itself. Being familiar with basic Laplace transforms and learning key properties of the unit step and unit impulse functions, they solve these differential equations and compare the interval of time when the coffee will be at its peak level of enjoyment. This paper includes an implementation guide, grading rubric, example solutions, and example assessment questions. [ABSTRACT FROM AUTHOR]

Background: Coffee is one of the most consumed beverages in the world. Containing an abundance of bioactive molecules including polyphenols and flavonoids, the constituents of this beverage may exert antiproliferative, antioxidant and anti‐inflammatory effects. Methods: We conducted a systematic review to summarise the available evidence on the anticancer effects of coffee constituents and their potential therapeutic use for oral squamous cell carcinoma (OSCC). Studies were identified through a comprehensive search of OVID MEDLINE, OVID EMBASE and Web of Science, including articles from any year up to 15 May 2023. Results: Of the 60 reviewed papers, 45 were in vitro, 1 was in silico and 8 were in vivo exclusively. The remaining studies combined elements of more than one study type. A total of 55 studies demonstrated anti‐proliferative effects, whilst 12 studies also investigated migration and invasion of neoplastic cells. The constituents studied most frequently were quercetin and epigallocatechin gallate (EGCG), demonstrating various cytotoxic effects whilst also influencing apoptotic mechanisms in cancer cell lines. Dose‐dependent responses were consistently found amongst the studied constituents. Conclusion: Whilst there was heterogeneity of study models and methods, consistent use of specific models such as SCC25 for in vitro studies and golden hamsters for in vivo studies enabled relative comparability. The constituents of coffee have gained significant interest over the last 30 years, particularly in the last decade, and present an area of interest with significant public health implications. Currently, there is a paucity of literature on utilization of active coffee constituents for the therapeutic treatment of oral cancers. [ABSTRACT FROM AUTHOR]

INTRODUCTION Certain foods and beverages are associated with smoking craving. However, only few studies have explored the relationship between food or beverage-related and taste-associated smoking craving. In this study, we aimed to identify the types of foods related to smoking craving in Japanese individuals who smoke cigarettes or heated tobacco products (HTPs). METHODS A total of 657 individuals (HTP and cigarette smokers and never smokers) participated in this cross-sectional study. Participants were asked what foods/ beverages, tastes, seasonings, cooking methods, and cuisine categories, made them want to smoke and what foods they consumed. RESULTS Alcoholic beverages such as beer, coffee, and fat-rich foods were associated with a higher likelihood of smoking craving. Fruits, dairy products such as milk, and sweet and sour tastes, were associated with a lower likelihood of smoking craving. The daily intake of fruit and dairy products was significantly lower in cigarette and HTP smokers than in non-smokers (median fruit intake: nonsmokers, 46.4 g/1000 kcal/day; cigarette smokers, 22.2 g/1000 kcal/day; HTP smokers, 31.4 g/1000 kcal/day; p<0.001; median dairy product intake: nonsmokers, 76.3 g/day; cigarette smokers, 48.2 g/day; HTP smokers, 57.6 g/day; p<0.001) as assessed using a food frequency questionnaire (BDHQ). CONCLUSIONS Specific foods and beverages such as alcohol, fruits, and dairy products are related to smoking craving, and their intake differs according to smoking status. [ABSTRACT FROM AUTHOR]

Spent Coffee Ground (SCG) is the main coffee industry by-product, rich in dietary fibers and polyphenols. The extractable material of SCG was fractionated, and the phenolic compounds were identified and quantified. Chlorogenic and neochlorogenic acids were identified as the main phenolic components, and the Total Phenolic Content (TPC) of SCG was determined to be 2.16% (dry SCG basis). Furthermore, SCG was characterized in terms of Total Dietary Fiber content, which amounted to 66%. The SCG was valorized for the development of a bakery product (cookie) enhanced with fiber and bioactive polyphenols. Cookies were produced with the addition of 4% and 7% dry and defatted SCG (baked cookie basis). The produced cookie prototypes presented TPC and dietary fiber dependent on the addition level of SCG. TPC values were determined at 588 and 1017 ppm, while dietary fiber values were at 2.7 and 4.6%, respectively. The shelf life of the cookies was monitored over 143 days at three different temperatures (25 °C, 35 °C, and 45 °C) in terms of texture (hardness), color, Peroxide Value (PV), and TPC. It was observed that the PV value significantly increased in samples with incorporated SCG, stored at 45 °C, while in those stored at 25 °C and 35 °C, PV remained at low levels. The TPC of the SCG-enriched samples remained practically constant during the shelf life analysis, while color and hardness increased (mathematically modeled). SCG-added cookies were characterized by increased darkness, increased hardness, and a mild (desirable) coffee flavor. The overall sensory impression scores for 0%, 4%, and 7% SCG-added cookies were 7.5, 8.0, and 8.2, respectively. Based on sensory evaluation test results, the shelf lives of 0%, 4%, and 7% SCG at 25 °C were 359, 435, and 471 days, respectively. Overall, SCG is a potentially valuable ingredient that can be used to develop innovative food (baked) products with enhanced nutritional value and increased shelf life. [ABSTRACT FROM AUTHOR]

The sustainability of global coffee supply is threatened by production challenges worsening with every decade since the turn of the 21st century. Coffee is among the most popular beverages in the world, and its production supports livelihoods of millions of people, mostly smallholder farmers. With a global market value exceeding US$130 billion, the coffee industry is a source of export revenue for producing countries, the majority of which are developing nations in the Global South. Climate change, pests, and diseases continue to hamper productivity, profitability, and countries' competitiveness in the global market. At the same time, the global demand for coffee continues to rise. A crucial pillar to safeguarding the future of coffee is continuously developing improved varieties suitable for the changing environment, and that address the needs of farmers and the industry. Yet, most national breeding programs are grossly out of touch with climate change reality and market dynamics. Working in isolation, these programs are constrained by unstable funding, limited sources of genetic variability, and inaccessibility of modern technologies necessary to accelerate the breeding process. We review here key production challenges, status of genetic diversity, and breeding approaches. Additionally, we explore opportunities in leveraging a pre-competitive collaborative breeding approach encompassing sharing of germplasm, and cross-border multi-environment trials in developing next-generation cultivars. We argue that breeding efforts should be informed by the needs of all the stakeholders in the supply chain including researchers, smallholder farmers, small and medium-sized enterprises investing in coffee processing and roasting, and consumers. Using emerging and reviving producers in Southeast Asia and Eastern Africa as a model, we explore how a paradigm shift in coffee breeding from the historically nation-centric approach to a more forward-looking collaborative model could improve the efficiency of variety improvement in face of climate change and growing market demand.

Background: To evaluate the effect of staining beverages on the color-changing of resin-infiltrated artificial white spot lesions (WSLs). Methods: Thirty-five artificial WSLs were created by pH cycling on flat bovine teeth specimens. The WSLs were treated with resin infiltration and were divided into five groups based on staining beverages: artificial saliva, coffee, wine, green tea, and Coca-Cola. These specimens were subjected to a 28-day exposure to the respective beverages. Color stability was assessed using a spectrophotometer at different time points: baseline, after 7, 14, 21, and 28 days of exposure, and repolishing. The color difference (∆E) between each time point and the baseline was calculated. Statistical analysis was performed using two-way measures ANOVA with a significance level of p = 0.05. Results: All resin-infiltrated specimens exposed to staining beverages for 7 days exhibited more significant color changes than those exposed to artificial saliva. The color change patterns varied based on the type of beverage. The color alterations intensified with extended immersion in the wine and Coca-Cola groups, while there were no significant differences in the color of specimens after 28 days of immersion in the coffee and green tea groups. However, after cleaning with pumice powder, all specimens showed significantly reduced color changes compared to those observed after 28 days of immersion, except those immersed in coffee. Conclusions: Exposure of resin-infiltrated bovine tooth specimens to staining beverages resulted in a significant color alteration as the immersion time increased. However, the staining effect could be minimized by cleaning with pumice powder, except for the coffee group. Clinical relevance: After resin infiltration treatment, patients should be advised to minimize the consumption of colored beverages to prevent staining that could impact esthetic appearance.

Climate change increases the risk of coffee yield due to the genotype-dependent effects of water deficit on coffee physiology. The goal of this research was to evaluate how water deficit altered the physiological and growth characteristics of arabica coffee (Coffea arabica L.). Water status, photosynthetic response to CO2 intercellular concentration (A/Ci curves) and growth parameters were evaluated in seedlings of four genotypes (Catimor ECU 02, Cavimor ECU, red Caturra and Sarchimor 4260). Most of the physiological traits evaluated differed significantly among genotypes. Between control and water deficit plants, significant variations occurred in the A/Ci parameters, showing a wide range of values for net photosynthetic rate, stomatal conductance, and water use efficiency, with decreases ranging from 4 to 74%. Maximum electron transport rate through photosystem II, highest rate of RuBisCO carboxylation, and triose phosphate utilization rate were all strongly decreased by water deficit 61% (red Caturra and Sarchimor 4260), followed by Cavimor ECU (35%) and Catimor ECU 02 (24%). Differences in response to water deficit among genotypes suggest possible genotypic differences in tolerance. The results indicated that Catimor ECU 02 and Cavimor ECU were less sensitive to water deficit, while red Caturra and Sarchimor 4260 were the most susceptible. [ABSTRACT FROM AUTHOR]

Honey was reported numerous benefit containing nutritional ingredients and phytochemical such as polyphenol, flavonoid was widely used around the world. In this study, the physicochemical characteristics on the quality of coffee flower honey has been evaluated during storage. The honey was collected from Dak Lak, Buon Me Thuot, and Kon Tum province in Vietnam and stored at room temperature (30 -32°C) for 12 month. Total sugar, reducing sugar, hydroxymethylfurfural (HMF), acid value, total polyphenol content (TPC) and total flavonoid content (TFC) were evaluated for each two month to determine the quality of sensory quality and nutritional value. After 12 month storage time, the content of total sugar, and reducing sugar gradually decreased along with the increase of HMF and acid content in the coffee flower honey samples a lead to sweetness of honey is decrease, acidity, and color increase, which is a signal indicating a decline in sensory quality and nutritional value. The content of TPC and TFC increased during the first 6 -10 months of storage and then also tended to decrease, indicating that coffee flower honey should not be stored for too long (more than 10 months) because of phytochemicals reducing.
