The Espresso Protocol (TEP) was used to assess the quality of coffee beans through espresso extraction incorporating a sensory approach. TEP includes overall quality evaluation and attribute evaluation using check-all-that-apply (CATA). This study aims to evaluate the repeatability of TEP when used by experts and to compare cross-cultural assessments to determine its applicability across different countries with diverse coffee cultures. Experts with over three years of experience in the coffee industry from five countries—France (n = 7), India (n = 12), Italy (n = 7), the Republic of Korea (n = 10), and the USA (n = 10)—participated in our study. The experiment was conducted in three replications using eight different single-origin coffee samples over two or three consecutive days. Cluster analysis using CATA data was performed to verify the repeatability of individual participants in the characterization of espresso samples, revealing that most participants were repeatable in their three-time evaluations. Moreover, a significant homogeneity index demonstrated a high degree of similarity in the sensory characteristics used by experts from each country, although cultural differences were observed in the terminology used to describe coffee. In conclusion, the repeatability of individual experts and the reliability of TEP were successfully demonstrated. However, some differences in sensory evaluations were noted across cultures; these were likely influenced by differences in the use of terminology, which emphasizes the need for training in the coffee lexicon.

One of the most significant industries in the world is the meat sector, and development into new goods is ongoing due to high customer demand and fierce market competition. Products made from chicken are widely favored. This phenomenon can be attributed to the lack of cultural or religious restrictions on this meat. The study looks into how using two distinct types of iron-rich fillings impacts the sensory profile of classic chicken roulades. The purpose of the study is to determine how changes in sensory qualities (such as taste, texture, and flavor) affect product acceptance among customers. This approach uses methods like check-all-that-apply (CATA), principal component analysis (PCA), external preference mapping (PrefMap), and penalty analysis to explore the impact of adding chicken offals and spinach as fillings on the sensory profile of traditional chicken meat roulades. This approach seeks to expand the meat product category, create new goods that use both plant and animal components, invent new ways to use offals and spinach in the market, and ensure that consumers accept these new products. Based on the results of our investigation, the type of filling utilized in the roulades showed the most differences across all sensory tests. According to hedonic analysis and preference mapping (PrefMap), the majority of customers favored roulades with spinach fillings as opposed to those containing chicken offals, which only a small portion of customers liked. Variations in consumer preference for roulades filled with chicken offals were noted in the anatomical region, with slightly greater preference for roulades made from chicken breast. However, this (anatomical region used) did not significantly affect the outcomes of all sensory tests. The spinach stuffing was found to be quite popular with the customers, even outperforming traditional chicken roulades, making it the most significant influence. Based on consumer appreciation, this suggests that the spinach-filled chicken roulades may be a viable option for meat products in the future. [ABSTRACT FROM AUTHOR]

Understanding consumers' sensory preferences for dairy products is essential. This study employed sensory analysis and instrumental techniques to analyze the flavor of pasteurized milk and UHT milk. There were 6 milk samples with similar fat content (4.0–4.6 g/100 mL) and protein content (3.2–3.8 g/100 mL). Sensory data from consumer tests was collected using check-all-that-apply (n = 100) and 9-point hedonic preferences. Research showed that Chinese consumers could distinguish the flavor of the 2 types of milk, and UHT milk showed a higher preference score, which may be due to the more pronounced milky flavor and sweet taste of UHT milk. A total of 48 aroma-active compounds were sniffed through 2-dimensional gas chromatography olfactometry time-of-flight MS, among which 11 were determined as key aroma-active compounds. Correlation analysis showed that milky odor, sweetness, and aftertaste-milky were positively correlated with γ-dodecalactone and γ-nonanolactone. Cooked and oxidized taste were positively correlated with 1-octen-3-ol and E-2-octenal. This study is important for developing Chinese dairy products and exporting dairy products to China by multinational companies.

Summary: Mead is an ancient alcoholic beverage that lacks a large market share in Canada. This study aimed to identify consumer perception of mead, which sensory properties lead to liking and disliking of mead, and how participants would consume mead in their everyday lives. A sub‐objective was to evaluate the use of a written scenario on consumers' liking and emotional response to mead. Alcoholic beverage consumers (n = 122) were recruited to evaluate six commercial mead samples. Initially, consumers completed a word association task about mead. Then, the participants were split into two groups; one group evaluated the samples after writing a consumption scenario, and the other without a scenario. The participants evaluated the samples using hedonic scales and check‐all‐that‐apply questions (sensory properties and emotional responses). Findings showed that mead was associated with historical references and honey, as well as different sensory properties and other alcoholic beverages (beer, wine, and cider). Consumers preferred meads with higher alcoholic content, and meads that they perceived to be sweet and have floral and apple flavours. The use of the written scenario increased hedonic scores for flavour, appearance, and overall liking, as well as their selection of positive emotions when evaluating the mead samples. This study identified consumers prefer meads that are sweet and have a higher alcohol content. [ABSTRACT FROM AUTHOR]

The incorporation of okara, a by-product of soybean milk production, into gluten-free products such as crispy waffles poses challenges due to the absence of gluten's viscoelastic properties and the high fiber content of okara. This study aimed to evaluate the effects of okara flour on the rheological properties, physical attributes, and sensory qualities of gluten-free waffles. Waffle batters with varying levels of okara flour (10%, 20%, 30%, and 40%) were prepared, and their rheological properties were analyzed using oscillatory shear and creep-recovery tests. Physical properties, proximate composition, cholesterol and glucose adsorption capacities, storage stability, and sensory attributes were also assessed. The results demonstrated that increasing okara flour content improved batter elasticity and viscosity (with complex viscosity reaching up to 10,923 Pa·s for 40% okara flour) but decreased spread ratio by up to 45% and increased moisture content by approximately 2.7%. Higher okara content also led to a 16% decrease in brightness (L*) and increased hardness, reaching 325.26 g/s at 40% substitution. Sensory evaluation revealed that waffles with 30% okara flour were preferred for their texture and overall liking, with a score of 7.43 compared to higher substitution levels. Cholesterol and glucose adsorption capacities were high in okara flour, contributing to potential health benefits. Storage stability tests showed acceptable moisture content, water activity, and microbiological safety over 60 days, though hardness decreased by about 42%. In conclusion, okara flour enhances the nutritional profile of gluten-free waffles, but its impact on texture and flavor requires careful formulation adjustments to optimize consumer acceptance.

With growing consumer demand for plant‐based products that mimic the eating experience of animal‐based products, there is a need for improvement in instrumental measurements of sensory texture. This study aimed to characterize textural differences between dairy and non‐dairy cheeses, and to investigate whether Large Amplitude Oscillatory Shear (LAOS) rheometry could discriminate sensory texture better than Texture profile analysis. Commercial dairy and non‐dairy cheddar, mozzarella, and cream cheese were selected to provide a wide range of textures. Sensory evaluation used the check‐all‐that‐apply methodology with 73 consumers. Texture profile analysis force‐distance data were analyzed empirically, and also converted to stress and strain (see https://shiny.csiro.au/texture%5fdash). The major textural differences between dairy and non‐dairy cheddar were related to structural cohesion, according to both instrumental measures (dairy cheddar had 1.5‐fold higher failure stress and 2.2‐fold higher failure strain) and sensory measurements (dairy cheddar was more chewy and less crumbly). In contrast, cream cheeses showed similar textural properties using sensory testing but significant instrumental differences (non‐dairy cream cheese had 5.7‐fold higher modulus of deformability, 4.7‐fold higher failure stress). For mozzarella, there were large differences in both sensory attributes (chewy, crumbly, jelly‐like, stretchy) and instrumental parameters (13.6‐fold difference in modulus, 2.7‐fold difference in failure stress). LAOS rheometry gave insights into the mechanisms by which samples absorbed or dissipated mechanical energy at nonlinear strains. The LAOS parameter G3′/G1′$$ {G}_3^{\prime }/{G}_1^{\prime } $$ correlated well with sensory attributes creamy, fatty/oily, and moist, indicating the potential of this technique to measure structural phenomena linked to sensory attributes that resonate with consumers.

Sous vide meat is an emerging food category, the consumption of which has increased owing to greater convenience, sensory traits, elderly consumers acceptance, and low‐cost cuts use. However, required prolonged thermal treatment to achieve desired tenderness, impact energy‐consumption besides triggering lipid oxidation, undesired off‐flavors, and cooked meat profiles. Using a response surface methodology (RSM), this study evaluated the effects of the vegetal proteolytic papain (0 to 20 mg/kg) and low‐temperature sous vide cooking (SVC) time (1 to 8 h at 65°C) in low‐value marinated M. semitendinosus beefsteaks on technological characteristics associated with tenderness, and lipid oxidation. Additionally, the sensory profile traits of the pre‐selected treatments were described using check‐all‐that‐apply (CATA) and preference mapping. Shear force (WBsSF) was reduced with greater papain addition, whereas higher cooking losses (CL) were observed with longer SVC cooking times. Both the released total collagen and TBARS values increased with increasing papain concentrations and SVC times. Combining high levels of papain (>10 mg/kg) and SVC time (>6 h) resulted in lower WBsSF values (<20 N) but higher CL (>27%) and the CATA descriptors "aftertaste" and "mushy." The optimized conditions (14 mg/kg papain; 2 h SVC) also reduced WBsSF values (<26 N) with lower CL (<20%) and were most preferred and described as "juicy" and "tender" by consumers. Observed results suggest that combined mild SVC and papain may potentiate tenderness, conjointly favor juiciness and oxidation, further representing a promising tool for reducing SVC time without compromising valued sous vide sensory traits.

Consumers have become interested in plant-based alternatives to animal-based products. One of the under-studied alternatives is plant-based eggs (PBEs). This research investigated PBEs relative to conventional eggs and tofu scramble—another plant-based alternative. Firstly, participants (n = 93) completed a word association task asking them about PBEs. Participants then evaluated the different food samples using hedonic scales, check-all-that-apply (CATA), and temporal check-all-that-apply (TCATA), as well as identified their emotional response and proposed use for PBEs. Participants were interested in plant-based alternatives, including PBEs, but they were concerned about the sensory properties. When they evaluated the different samples, the flavour and texture of the PBEs were disliked in comparison to the eggs. This result may be due to the beany, bitterness, and off-flavour attributes associated with the PBEs. Participants also associated the PBEs with negative emotions. The liking of tofu scramble was not significantly different from the eggs, and the eggs and tofu scramble were mainly associated with positive emotions. During the TCATA evaluation, the participants focused on the flavour attributes of PBEs, while their evaluation of the eggs was dominated by the textural attributes. Whether following a plant-based diet or not, consumers are interested in PBEs, but the sensory properties of PBEs need to be improved before they are willing to adopt them into their diet. This study is one of the first to evaluate the sensory properties of PBEs, as well as consumers' emotional response to them and their attitudes about PBEs. [ABSTRACT FROM AUTHOR]

In this study, the check-all-that-apply (CATA) method, headspace solid phase microextraction (HS-SPME)-Arrow combined with gas chromatography-mass spectrometry (GC-MS) and gas chromatography-mass spectrometry-olfactometry (GC-MS-O) were used to analyze volatile flavor substances that affect the sensory differences among milk from four pastures. The results of the CATA questionnaire showed that milky aroma, creamy aroma, fragrant and sweet aroma, milky aroma, plastic odor, cooked odor and metallic odor were significantly different among the four milk samples (P < 0.05), and milk from pasture I were the most preferred by respondents, and the preference scores of milk from pastures III and IV were lower. Totally 14 aroma-active substances with an aroma intensity greater than or equal to 1 were obtained from the four milk samples through olfactometry. Using partial least squares regression analysis (PLSR), correlation analysis among sensory data, aroma-active substances and milk samples was conducted. The results showed that milky and creamy aroma from pasture I were prominent, which was strongly correlated with 2-heptanone, butanoic acid, decanoic acid, and hexanoic acid. Milk from pasture II showed a fragrant and sweet aroma, which may be related to the concentration of limonene. Milk from pasture III had prominent metallic, plastic, and milky odors, which may be related to 1-octene-3-alcohol. Milk from pasture IV had a cooked odor, which mainly came from hexanal and styrene.

This study explores the pivotal roles of microbiological safety, sensory qualities, packaging efficiency, and consumer preferences in determining the success of roasted pickled fish powder (RPFP) variants in the online marketplace. The comparison of the nutritional composition of the developed RPFP variants with a commercial benchmark reveals significant differences: the protein content in the herbal flavor variant is found to be 28.97%, which is lower than the 40.17% found in the commercial benchmark, while the fat content in the spicy flavor variant is measured at 19.51%, exceeding the 10.60% present in the benchmark. Additionally, the herbal flavor boasts a superior dietary fiber content of 14.23%, highlighting the intricate relationship between nutritional content and sensory attributes, which is critical in online retail, where physical product evaluation is not possible. Our comprehensive approach, evaluating both nutritional and sensory dimensions, introduces a novel perspective to the adaptation of traditional food products for e-commerce, addressing a gap in the literature. Despite this study's limitations, including a focused market analysis and constrained sample size, our findings offer valuable insights into enhancing product quality and integrity in the digital marketplace, positioning RPFP for competitive success while suggesting directions for future research.

This study aimed to investigate consumer sensory profiles and liking of Parmigiano Reggiano PDO cheese produced with milk from cows reared indoors and fed with different forage sources, i.e., dry hay and fresh forage. Two cheese samples were tested by 119 Italian subjects, following a protocol that included a Check-All-That-Apply method to assess the sensory profile, a Just-About-Right scale to evaluate the adequacy of attributes, and questions on liking (9-point hedonic scale). A questionnaire related to personal information and consumption habits was also submitted. The color of the two samples, based on image analysis, was different: the sample produced with milk from the dairy cows fed fresh forage had a higher intensity of yellow than the other; they were also described differently (p ≤ 0.05) by participants in the consumer test. Indeed, Parmigiano Reggiano produced with milk from the cows that were fed dry hay was mainly characterized by a "fresh milk" and "solubility", while the sample produced with milk from cows fed fresh forage was described as "yellow", "seasoned", "pungent", and with a "cheese crust" flavor. Even if no significant differences were observed between the two samples in terms of liking (p ≤ 0.05), the attribute "graininess" showed a great impact on liking ratings together with "yellow" (p ≤ 0.05), apparently corresponding to a specific expectation regarding the intensity of these attributes. Data were also analyzed according to the gender of consumers, highlighting that for women, the adequacy of "fresh milk", "sweet", and "graininess" greatly impacted liking for the cheese from cows fed dry hay.

The objective of this study was to investigate the sensory profiles of basil syrups formulated with different contents of basil leaf extract and sugar, and to determine the key attributes of consumer liking. Moreover, this study also measured consumers’ perceptions in two sensory evaluation settings of blind and non-blind (informed) tests. Sixty adult consumers were involved in the evaluation. The basil leaf extract and sugar contents influenced the sensorial characteristic of basil syrups. Moreover, consumers had different perceptions and changed their preferences for this product in different sensory evaluation settings. Information related to ingredients and sugar contents was demonstrated to consumers to enable the shift in their preferences. Consumers perceived the basil syrups as significantly healthier in the non-blind setting ( p

The incorporation of okara, a by-product of soybean milk production, into gluten-free products such as crispy waffles poses challenges due to the absence of gluten’s viscoelastic properties and the high fiber content of okara. This study aimed to evaluate the effects of okara flour on the rheological properties, physical attributes, and sensory qualities of gluten-free waffles. Waffle batters with varying levels of okara flour (10%, 20%, 30%, and 40%) were prepared, and their rheological properties were analyzed using oscillatory shear and creep-recovery tests. Physical properties, proximate composition, cholesterol and glucose adsorption capacities, storage stability, and sensory attributes were also assessed. The results demonstrated that increasing okara flour content improved batter elasticity and viscosity (with complex viscosity reaching up to 10,923 Pa·s for 40% okara flour) but decreased spread ratio by up to 45% and increased moisture content by approximately 2.7%. Higher okara content also led to a 16% decrease in brightness (L*) and increased hardness, reaching 325.26 g/s at 40% substitution. Sensory evaluation revealed that waffles with 30% okara flour were preferred for their texture and overall liking, with a score of 7.43 compared to higher substitution levels. Cholesterol and glucose adsorption capacities were high in okara flour, contributing to potential health benefits. Storage stability tests showed acceptable moisture content, water activity, and microbiological safety over 60 days, though hardness decreased by about 42%. In conclusion, okara flour enhances the nutritional profile of gluten-free waffles, but its impact on texture and flavor requires careful formulation adjustments to optimize consumer acceptance.

Taste sensitivity can have a significant impact on consumers' food choices. Consumers' taster status and emotions can be guided by sensory information of sugared products. This paper aimed to develop emotional lexicons for sugar-free chocolates based on consumers' taster status applying the check-all-that-apply (CATA) methodology. South African respondents' (n = 153) bitter perception was evaluated with n-propylthiouracil (PROP) paper strips. Respondents received one sugar-free dark chocolate and one sugar-free milk chocolate and completed an electronic questionnaire. Respondents mainly purchased chocolate for its flavour, and enjoyed the taste of the sugar-free dark chocolate more than sugar-free milk chocolate. The non-tasters (>50%) chose positive emotions for sugar-free milk chocolate, while the medium tasters, selected more positive emotions for dark chocolate. The supertasters selected the most negative emotions for the sugar-free dark chocolate. Practical significant associations were found between the non-tasters and the emotion guilty, as well as between the supertasters and the emotions, discontented and disgust. Each taster status requires the development of a distinctive lexicon to be emotionally satisfied by sugar-free products. [ABSTRACT FROM AUTHOR]

Ice cream formulations with varying amounts of added whey protein were created for those living with dysphagia in long‐term care facilities (LTCs) to improve protein and fluid intake. The samples of thickened ice cream included a control (0% whey protein [WP]) and formulations with 6% (6WP), 8% (8WP), 10% (10WP), 12% (12WP) and 14% (14WP) added whey protein by volume. The consistency of the samples was assessed using the International Dysphagia Diet Standardization Initiative (IDDSI) Spoon Tilt Test, a sensory trial (n = 102) using hedonic scales and check‐all‐that‐apply (CATA) and another sensory trial (n = 96) using temporal check‐all‐that‐apply (TCATA). The whey protein increased the acceptability of the thickened ice cream except for the 12WP and 14WP formulations. The formulations with higher amounts of whey protein were associated with bitterness, custard/eggy flavor, and mouthcoating. The TCATA identified that the addition of whey protein led to slippery, gritty, and grainy attributes being perceived in the thickened ice cream. The study identified that 10% whey protein by volume can be added to thickened ice cream without impacting its' acceptability and the 6WP, 8WP, and 10WP formulations were liked significantly more than the control (without whey protein).

Screening the suitability of soy sauce for specific cooking methods from various products is beneficial for the fine development of the soy sauce industry. Multiple sensory evaluation and gas chromatography-mass spectrometry/olfactometry (GC-MS/O) analysis were combined to decode the suitability of soy sauces for cold dishes and characterize their differential aroma-active compounds. Thirty-two kinds of soy sauce with 42 sensory descriptors were determined via a check-all-that-apply analysis, and werefurther classified into six categories via a cluster analysis. The sensory evaluation results showed that seven soy sauce samples had the highest acceptance in each category. Solid-phase microextraction and solid phase extraction results combined with the GC-MS/O analysis results showed that a total of 38 aroma-active compounds were identified in seven soy sauce samples, among which 2-methoxy-phenol (6–93), ethyl acetate (2–48), 3-methyl-1-butanol (4–30), 3-methyl-butanal (5–24), methional (0–22), dimethyl trisulfide (5–19) and dimethyl disulfide (0–8) showed a higher relative odor activity value (ROAV). A partial least squares regression prediction combined with additional tests further confirmed that 2,5-dimethyl-pyrazine; 2,6-dimethyl-pyrazine; and 2-ethyl-6-methyl-pyrazine significantly contributed to the roasted attributes, methional significantly contributed to the sauce-like notes, ethanol significantly contributed to the alcoholic notes and 2-methoxy-phenol significantly contributed to the smoky notes. 2,5-Dimethyl-pyrazine; methional; 2,6-dimethyl-pyrazine and 2-ethyl-6-methyl-pyrazine significantly contributed to the caramel-like attributes.

The impact of the growing environment on the aroma of agricultural products such as wine, coffee, or tea has been investigated in detail, leading to the concept of regional identity; however, there have been only limited studies examining regional variation in hops. A systematic investigation of Cascade and Mosaic® hops from the 2020 harvest year grown at 39 different locations in Oregon and Washington was performed using chemical/instrumental and human sensory analyses, which revealed significant between-state and within-state differences for both varieties, suggesting substantial regional and subregional identity effects. A subset of 14 hop samples was selected to produce standardized single-hop beers (IPA) in pilot scale. Sensory evaluation of the beers revealed similar regional-dependent results as observed for the hops with slightly stronger fruity, citrus, and tropical notes but weaker herbal, grassy, and woody notes in the beers compared to hops, suggesting that the regional identity effect was observable in beer.

Background: Finger foods, foods that can be eaten without cutlery, may be a strategy to increase autonomy and food intake amongst older adults with motoric eating difficulties. In order to develop optimal finger foods, knowledge about sensory preferences and requirements in the target population is needed. Objective: To assess sensory preferences and requirements amongst Swedish older adults with motoric eating difficulties. Design: Check-all-that-apply (CATA), a methodology that does not require much cognitive effort, was used to collect survey data about sensory preferences and requirements for everyday meals from 15 older adults with motoric eating difficulties. The CATA-questionnaire was structured according to the Swedish meal order (breakfast, lunch, dinner, snack and fika) and consisted of 29 attributes compiled through a literature review. Results: Through both qualitative and quantitative data analysis, it was found that flavourful, flavour intensity, spicy and both Swedish and ethnic flavours were important attributes related to food flavour. Although most participants preferred crispy and coarse textures, a few participants found soft, smooth and fine textures important. Moreover, colourful meals and serving components separated on the plate were important for the appearance of lunch and dinner. Discussion: A diverse range of flavours, flavour enhancement and a balance between the basic tastes and spiciness may increase the flavour perception. Finger foods should be offered in the full range of flavours available to the general older adults’ population. The variation in the demand for texture may be related to chewing and swallowing difficulties, and textures that require moderate chewing and easy swallowing are, therefore, optimal for finger foods. Separating meal components on the plate may make it easier to distinguish the components. Conclusion: Chemosensory impairments, chewing and swallowing difficulties, and visual disturbances are important to consider in the development of finger foods.

Aromatic white wines contain monoterpenes that can alter aroma qualities based on their concentration and enantiomeric ratios. Limonene has been identified as a monoterpene that is used to differentiate monovarietal white wines. The aim of this study was to evaluate the influence of limonene on aroma perception at different enantiomeric ratios. Its interaction with linalool and α-terpineol compounds was also investigated. Eighteen model wines were created with different ratios and/or concentrations of limonene and diverse concentrations of linalool and α-terpineol. Triangle tests, check-all-that-apply (CATA) and descriptive analysis were used to evaluate the aroma of the wines. Results show that different limonene ratios had no influence on wine aroma. Descriptive analysis showed that the addition of only limonene influenced citrus characteristics depending on the concentration. Linalool addition did not alter aroma quality when the limonene was at low concentrations, but it did change aroma perception at high limonene levels. α-Terpineol only altered the aroma of the wine at medium and high concentrations. At high concentrations, linalool and α-terpineol presented tropical aromas with some floral notes, irrespective of limonene levels. Depending on the desired aroma qualities of the wine, altering the monoterpene content resulted in very different aromatic wines. [ABSTRACT FROM AUTHOR]

In 2020, a single-response-based, valence × arousal circumplex-inspired emotion questionnaire (CEQ) was developed. Using a between-participants design, previous studies have found that a multiple response (MR) condition better discriminated test samples (e.g., written food names) based on their evoked emotions than a single response (SR) condition. This research, comprising Studies 1 and 2, aimed to determine the effect of response conditions (i.e., SR vs. MR) on emotional responses to food image samples, using a within-participants design. In Study 1, 105 Korean participants were asked to select a pair of emotion terms (i.e., SR condition) or select all pairs representing their evoked emotions (i.e., MR condition) from a list of 12 pairs of emotion terms of the CEQ, in response to the 14 food images. Both SR and MR conditions were tested within a remote (online) session. To minimize both a potential carry-over effect of the "within-participants design" and an influence of environmental factors in the remote testing, Study 2 asked 64 U.S. participants to do so over two separated sessions on two different days in a controlled laboratory setting. In both Studies 1 and 2, participants selected the CEQ's emotion-term pairs in the MR condition more frequently than in the SR condition, leading to the MR condition's higher capacity to discriminate test samples. While the configurations of the correspondence analysis biplots drawn in the SR and MR conditions were similar, those in the MR condition were more likely to be similar to the configurations of the principal component analysis biplots drawn from the ratings of valence and arousal for food image samples. In conclusion, this study provides robust empirical evidence that the MR condition can perform better in capturing sample differences in food-evoked emotions, while the SR condition is also effective in characterizing emotional profiles of test samples. Our findings will provide practical insights to sensory professionals, enabling them to effectively leverage the CEQ or its variants when measuring food-evoked emotions. [ABSTRACT FROM AUTHOR]

The hamburger has been targeted for substitution by numerous plant-based alternatives. However, many consumers find the taste of these alternatives lacking, and thus we proposed a hybrid meat and plant-based burger as a more acceptable alternative for these consumers. The burger was made from 50% meat (beef and pork, 4:1) and 50% plant-based ingredients, including texturised legume protein. Texture and sensory properties were evaluated instrumentally and through a consumer survey (n = 381) using the check-all-that-apply (CATA) method. Expressible moisture measurements indicated a significantly juicier eating experience for the hybrid compared to a beef burger (33.5% vs. 22.3%), which was supported by the CATA survey where "juicy" was used more to describe the hybrid than the beef burger (53% vs. 12%). Texture profile analysis showed the hybrid burger was significantly softer (Young's modulus: 332 ± 34 vs. 679 ± 80 kPa) and less cohesive than a beef burger (Ratio 0.48 ± 0.02 vs. 0.58 ± 0.01). Despite having different textural and CATA profiles, overall liking of the hybrid burger and a beef burger were not significantly different. Penalty analysis indicated that "meat flavour", "juiciness", "spiciness" and "saltiness" were the most important attributes for a burger. In conclusion, the hybrid burger had different attributes and was described with different CATA terms than a beef burger but had the same overall acceptability. [ABSTRACT FROM AUTHOR]

A flavor lexicon of milk coffee was developed based on the perceptions of Japanese consumers. To collect an exhaustive set of sensory terms for milk coffee, sixty types of samples were prepared. The samples were presented to 203 untrained panelists, and 456 sensory terms were collected. Following qualitative and quantitative screening, 53 terms were selected. The validity of the 53 terms was confirmed by check-allthat-apply (CATA) questions for six samples. The results indicated that the frequency of use of 42 terms was significantly different for the samples, and all terms were used at least once. In addition, the configuration of the six samples in the correspondence analysis of the CATA results was similar to that for a quantitative descriptive analysis conducted on the same samples. The developed flavor lexicon and its application to CATA will provide a new means for evaluating milk coffee from the perspective of Japanese consumers. [ABSTRACT FROM AUTHOR]

The addition of encapsulated bioactive compounds in food matrices allows obtaining foods with improved nutritional characteristics. In this study, chia oil (a source of omega-3) and astaxanthin were encapsulated in beads and added to commercial yogurt. Particles formulated using only sodium alginate (100SA) or mixed with whey protein aggregates (25WPA75SA) with incorporated chia oil and astaxanthin were added to yogurt. The stability of bioactive compounds added was evaluated, and consumer-based sensory analysis was applied using both a hedonic scale and Check-All-That-Apply method. The content of bioactive compounds in yogurts did not change after 28 days of storage. Yogurts exhibited good acceptability and the terms with high positive impact in all samples were sweet, pleasant flavor, smooth, creamy, pleasant particles, pleasant, and easy to swallow. Yogurt added with 25WPA75SA beads showed greater acceptance indicating that this matrix may be a good option to improve the consumption of astaxanthin and omega-3. [ABSTRACT FROM AUTHOR]

This study explores the pivotal roles of microbiological safety, sensory qualities, packaging efficiency, and consumer preferences in determining the success of roasted pickled fish powder (RPFP) variants in the online marketplace. The comparison of the nutritional composition of the developed RPFP variants with a commercial benchmark reveals significant differences: the protein content in the herbal flavor variant is found to be 28.97%, which is lower than the 40.17% found in the commercial benchmark, while the fat content in the spicy flavor variant is measured at 19.51%, exceeding the 10.60% present in the benchmark. Additionally, the herbal flavor boasts a superior dietary fiber content of 14.23%, highlighting the intricate relationship between nutritional content and sensory attributes, which is critical in online retail, where physical product evaluation is not possible. Our comprehensive approach, evaluating both nutritional and sensory dimensions, introduces a novel perspective to the adaptation of traditional food products for e-commerce, addressing a gap in the literature. Despite this study’s limitations, including a focused market analysis and constrained sample size, our findings offer valuable insights into enhancing product quality and integrity in the digital marketplace, positioning RPFP for competitive success while suggesting directions for future research.

BACKGROUND: Many consumers have a high salt intake and bread is a primary source because of its high rate of consumption. The inclusion of seaweeds has been proposed as an ingredient that could help reduce the salt content of food products. As such, the present study aimed to evaluate whether the amount of salt in bread could be reduced and the change in sensory properties be mitigated by the inclusion of brown seaweed. There were two different sensory trials conducted. In the first trial, participants (n = 102) evaluated bread made with brown seaweed (4% substitution for flour) with reduced amounts of salt (10%, 20%, 30%, 40% and 50%). The second trial asked participants (n = 98) to evaluate the control bread and the 20% salt‐reduced bread in blinded and informed conditions. In both sensory trials, the breads samples were assessed using hedonic scales, just‐about‐right scales, and check‐all‐that‐apply. RESULTS: The results showed that the 10% and 20% salt‐reduced breads were acceptable and associated with being soft, chewy and having no aftertaste. The other breads were associated with a dense, dry and strong aftertaste, along with not being salty enough for the consumers. When the breads were evaluated in informed conditions, the salt reduction label had a negative impact on the consumers' liking. CONCLUSION: The research emphasizes that salt‐reduced labels influence consumers' sensory perception. © 2023 The Authors.

This study aimed to explore the perception and sensory acceptance of Purple Maize (PM) breakfast cereals by a Brazilian panel. The extrudates were elaborated using 25%, 50%, 75%, and 100% PM in a commercial yellow corn base. A total of 117 consumers evaluated samples through an acceptability test (nine-point hedonic scale) followed by CATA questions (35 descriptive terms) and a market research questionnaire. The cereals formulated with 50% and 75% PM had the best scores (6) in color, aroma, texture, and overall liking during the acceptability test. Based on the penalty-lift analysis, Brazilian consumers' most important drivers of preference were the attractive color, crispy texture, and the natural and innovative purple color. In contrast, hard texture and brown color drivers negatively impacted the scores. In the market research, consumers indicated that they could eat the product both as a breakfast cereal and as a snack during the day; Likewise, they highlighted the possible health benefits, the innovative color, and the use of exotic raw materials as the best characteristics of the product. Therefore, using 50% PM or more allows for obtaining sustainable and nutritious breakfast cereals with characteristics of color, flavor, and texture well accepted by Brazilian consumers.

The assessment of different aroma families on tropical fruit aroma perception is still not well understood. This study aimed to investigate the effect of esters and volatile thiols on tropical fruit aroma perception in white wines. Four levels of thiols (none, low, medium and high) and three levels of esters (none, low, medium) were added to a dearomatized white wine base in a full factorial design. Check-All-That-Apply (CATA) was used to determine the aroma descriptors that most differentiated the wines followed by Sensory Descriptive Analysis (SDA) to evaluate the intensity of those significant aroma attributes. More than 78% of the total variance was described in the first two dimensions when using Canonical Variate Analysis. Tropical fruit aromas were associated with wines containing different levels of esters and ester-thiol combinations. Volatile thiols alone imparted an earthy aroma and were grouped with the control wine. The different ester-thiol combinations altered the tropical fruit aroma quality in the wines from citrus to passionfruit, pineapple and guava. Understanding the cause of tropical fruit aroma allows for targeted processing to achieve the desired wine sensory quality.

Taste sensitivity can have a significant impact on consumers’ food choices. Consumers’ taster status and emotions can be guided by sensory information of sugared products. This paper aimed to develop emotional lexicons for sugar-free chocolates based on consumers’ taster status applying the check-all-that-apply (CATA) methodology. South African respondents’ (n = 153) bitter perception was evaluated with n-propylthiouracil (PROP) paper strips. Respondents received one sugar-free dark chocolate and one sugar-free milk chocolate and completed an electronic questionnaire. Respondents mainly purchased chocolate for its flavour, and enjoyed the taste of the sugar-free dark chocolate more than sugar-free milk chocolate. The non-tasters (>50%) chose positive emotions for sugar-free milk chocolate, while the medium tasters, selected more positive emotions for dark chocolate. The supertasters selected the most negative emotions for the sugar-free dark chocolate. Practical significant associations were found between the non-tasters and the emotion guilty, as well as between the supertasters and the emotions, discontented and disgust. Each taster status requires the development of a distinctive lexicon to be emotionally satisfied by sugar-free products.

Screening the suitability of soy sauce for specific cooking methods from various products is beneficial for the fine development of the soy sauce industry. Multiple sensory evaluation and gas chromatography-mass spectrometry/olfactometry (GC-MS/O) analysis were combined to decode the suitability of soy sauces for cold dishes and characterize their differential aroma-active compounds. Thirty-two kinds of soy sauce with 42 sensory descriptors were determined via a check-all-that-apply analysis, and werefurther classified into six categories via a cluster analysis. The sensory evaluation results showed that seven soy sauce samples had the highest acceptance in each category. Solid-phase microextraction and solid phase extraction results combined with the GC-MS/O analysis results showed that a total of 38 aroma-active compounds were identified in seven soy sauce samples, among which 2-methoxy-phenol (6–93), ethyl acetate (2–48), 3-methyl-1-butanol (4–30), 3-methyl-butanal (5–24), methional (0–22), dimethyl trisulfide (5–19) and dimethyl disulfide (0–8) showed a higher relative odor activity value (ROAV). A partial least squares regression prediction combined with additional tests further confirmed that 2,5-dimethyl-pyrazine; 2,6-dimethyl-pyrazine; and 2-ethyl-6-methyl-pyrazine significantly contributed to the roasted attributes, methional significantly contributed to the sauce-like notes, ethanol significantly contributed to the alcoholic notes and 2-methoxy-phenol significantly contributed to the smoky notes. 2,5-Dimethyl-pyrazine; methional; 2,6-dimethyl-pyrazine and 2-ethyl-6-methyl-pyrazine significantly contributed to the caramel-like attributes.

To reduce animal protein consumption, new food products need to be created. Furthermore, there is a growing number of consumers who consciously act to reduce their meat consumption. Hybrid meat products (HMP) are food items that combine both plant and animal proteins. The objective of this study was to create a hybrid meat burger (HMB) using yellow pea and chicken and to evaluate the sensory properties of the new product using static (check‐all‐that‐apply [CATA]) and dynamic (temporal check‐all‐that‐apply [TCATA]) methods. Yellow pea flour was added to a chicken burger at 0% (control), 10%, 20%, 30%, and 40%. A sensory trial asked participants (n = 69) to evaluate the HMBs using hedonic scales and CATA. A second sensory trial asked experienced panelists (n = 14) to evaluate the items using TCATA. The addition of the yellow pea flour decreased the liking of the burgers, except for the 10% formulation. The burgers made with higher amounts of yellow pea were associated with off‐flavors (beany and nutty; significantly different from the control) during both CATA and TCATA tasks and detracted from consumers' liking. Juicy, moist, meaty, salty, and soft attributes increased the consumers' liking. The study identified that the addition of yellow pea to chicken burgers is only acceptable to consumers in small quantities (10%). In addition, the yellow peas contributed off‐flavors and a dry texture that was disliked by the consumers. Practical Application: The environmental impacts of livestock production have created a need to incorporate more plant‐based proteins into consumers' diets to increase sustainability. The market for meat alternatives, including hybrid meat products, is expanding; however, current products do not always meet consumers' expectations. Chicken is the fastest‐growing meat sector in North America, and therefore this study's objective was to determine the sensory properties of a burger made from chicken and pulses (yellow pea). It was found that if 10% of chicken in a burger was substituted with yellow pea, then the sensory properties and consumer liking were not significantly affected. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess if consumers could characterize wet- and dry-aged mutton flavor profiles using CATA (check-all-that-apply). A flavor lexicon was developed for mutton, and consumers assessed wet- and dry-aged mutton patties against this lexicon using CATA methodology. Results indicate that consumers most often associated caramel and roasted flavors with dry-aged patties, and "sheepy" and metallic flavors with wet-aged patties. Volatile analysis supported the consumer characterization as there were more Maillard reaction products, including pyrazines, which are associated with roasted and cooked flavors, found in the dry-aged patty volatile profile. More 1-octen-3-one, which is associated with metallic flavors, was found in the wet-aged patty volatile profile. These results provide validation that the lexicon utilized in this study (i) is suitable for the characterization of mutton flavor and (ii) will have applications for future investigations into the flavor components driving consumer liking for mutton.

This study aimed to develop sweet-and-sour sauces with partial substitution of tomato for avocado. Four sauces formulations containing 0%, 25%, 50%, and 75% avocado pulp were prepared. The pH, titratable acidity (TA), sugar: acid ratio, color, consistency, and syneresis analyses were performed. Sensory acceptance was measured by the hedonic, Just-about-right (JAR), and purchase intent scales. Besides, a check-all-that-apply (CATA) form was applied to obtain description data on the formulations. The results of the color parameters showed that treatments containing avocado had higher (p < 0.05) lightness and yellowness. The avocado addition improved the rheological measurements. There was an increase in the consistency of the sauces when the avocado concentration increased. The opposite was observed for syneresis, which decreased (p < 0.05) as the avocado pulp concentration increased. Sensory evaluation revealed good consumer acceptance, and purchase intent analysis showed that most consumers would buy this product. For JAR data, sauces with 50 and 75% avocado had highest values of consistency in the JAR region. The consumers who reported the formulation with 25% avocado to be "not enough" penalized its acceptance, reducing the overall acceptance. Based on the frequency of terms cited by consumers in the CATA, it was possible to consider specific terms for each formulation. The terms pleasant color, good taste, brightness, and good consistency were associated with high overall acceptance. These terms were mostly used for sauces with 25% and 50% avocado. Therefore, sweet-and-sour sauces based on a combination of tomato and avocado has proven to be a viable alternative to traditional ketchup. [ABSTRACT FROM AUTHOR]

Recently, the interest in tropical fruits has increased widely even beyond their production areas, but the perishable nature of these fruits makes their marketing difficult. However, due to its special sensory characteristics and nutritional value, lulo (Solanum quitoense Lam.) is a good candidate for product development to meet this ever-growing demand. Therefore, a lulo-powder-based soluble beverage was prepared according to previously established formulations. Thus, the aim of the present research was to obtain the sensory characterization, study consumers' overall acceptability, and identify drivers of liking for the new beverage. Eight samples were prepared with lulo juice or pulp + stevia, or a sweetener blend (erythritol + xylitol + stevia). Maltodextrin or inulin, as a drying aid, was added to freeze-dry the samples. The freeze-dried samples were rehydrated for consumption. The sensory characterization of the new beverage was carried out by using CATA questions with consumers (n = 69). The most influential attributes that affected acceptability were identified by using ideal product characterization and hedonic scores of the samples. The beverage formulations with stevia alone had the lowest acceptability. Most sensory differences among samples were found between the visual attributes. The attributes "clean", "homogeneous", "fruity" and "citrus" odor, "just-right acidity", "just-right sweetness", and "fresh" were necessary to increase global acceptance in the juice-only beverages (Js), whereas "cloudy", "off-odor", and "very acidic" negatively impacted acceptance. For products with pulp (Ps), "citrus" and "tropical fruit" odors, "just-right acidity", "just-right sweetness", and "fresh" attributes were needed to increase acceptance, while "cloudy" and "chemical/artificial" flavors negatively impacted acceptance. The lulo-powder-based soluble beverage was accepted by consumers; however, there is still potential for the sensory-quality improvement of this product. [ABSTRACT FROM AUTHOR]

ABSTRACT Ultra-refined yerba mate (URYM), with a final particle size of 5 to 12 microns, is an innovation in the market that aims to diversify and increase the consumption of yerba mate ( Ilex paraguariensis St. Hil) through its practicality and versatility of preparation. The present work seeks to evaluate the potential for applying naturally colored URYM in food products. The nature of this study was exploratory, adopting a chemical approach (analysis of the antioxidant potential); physical approach (color stability) and sensory perception. URYM is a suitable naturally colored food ingredient with natural antioxidant appeal. Methanolic extraction of URYM (MEUR) was more efficient in scavenging DPPH radicals compared with aqueous extract of URYM (AEUR) (959.5 vs . 638.1 µmol Trolox g–1). No differences were found between AEUR and MEUR for total phenolic content in mg GAE g–1 (266.4 and 339.0, respectively) and scavenging of ABTS radicals in µmol Trolox g–1 (1008.9 and 1053.8, respectively). Water was able to extract phenolic compounds with antioxidant activity. Ice cream, juice, cake, and cookies emerged as the food products in which consumers used URYM in their homemade foods. With good color stability (no difference between L*, a* and b* parameters during the six-day) and good acceptance, cake with URYM added has a profile described as tasty, sweet, soft, and mate flavor. The results also demonstrated consumer interest in food products and ingredients with a healthy appeal.
