Rusip is a spontaneously fermented anchovy product originating from Bangka Belitung province in Indonesia, used as umami seasoning. This study investigated the characteristics of rusip and its umami fractions to reveal umami peptides in rusip. Six commercial rusip samples from Bangka were analyzed for their proximate composition, pH, total titratable acids, NaCl, total sugars, free glutamic acid, nucleotide (adenosine monophosphate), and total amino acid composition. Umami taste intensity of water‐soluble extracts (WSE) was analyzed by a sensory panel. Total plate count and total lactic acid bacteria were also analyzed to assess the microbial variations between the samples. Stepwise ultrafiltration on the highest umami intensity WSE was conducted to obtain three fractions: >5 kDa, 3–5 kDa, and <3 kDa, followed by chromatography fractionation of fraction <3 kDa by Sephadex G‐15 gel to acquire umami fractions (F1–F4). Protein (28.94%–44.53% dry weight basis [db]) and NaCl (30.86%–55.73% db) were the major solids of rusip. Concentrations of free glutamic acid (5.79%–8.99% db) in rusip are related with umami intensities of WSE. F1 was the umami fraction with its residual umami amino acids higher than its free ones; therefore, F1 was also a peptide fraction. It contained peptides of 3–12 residues within the highest relative area. Their sequences contained those of umami peptides listed in BIOPEP database. Some of these peptides were also associated with bioactivities. This information could broaden the insight of umami peptides and their bioactivities in fermented foods. Practical Application: Rusip is used as a source of umami ingredient in food. The characteristics of product quality of rusip were reported in this study. In addition, the chemical and sensory characteristics as well as peptides of its umami fraction were also described. This information is important for the exploration of umami peptides from fish fermented products. [ABSTRACT FROM AUTHOR]

Whether the post-harvest process will greatly influence volatile or non-volatile coffee chemical compounds. Four post-harvest coffee processing techniques, namely natural, honey, fullwash, and wine, were evaluated in this study. This research aims to authenticate the volatile and non-volatile compounds of Robusta Jawa Bogor green bean as a differentiator in natural, fullwash, honey, and wine processing. Using HS-SPME-GC-MS and LC-MS, we identified a total of 128 volatile compounds (113 in natural, 111 in honey, 100 in fullwash, and 126 in wine), as well as 105 non-volatile compounds (77 in natural, 73 in honey, 66 in fullwash, and 93 in wine). The study found volatile compounds like ethyl cinnamate potential marker for honey processing. A potential marker for natural and wine processing is 1- isopropyl-3 methylbenzene. Some potential markers for wine processing are (E)-4-hexen-1-ol, 5-methyl-2-hexanol, diethyl succinate, ketoisophorone, and 4-ethyl-2-methoxyphenol. Non-volatile compounds like 1-naphthoic, [4]-gingerol, and theophylline are non-volatile markers for natural processing. Succinic acid is a non-volatile marker for natural and wine processing. While maleic acid and adenosine are markers for honey processing, adenine is a marker for wine processing. In contrast, fullwash does not have any volatile and non-volatile marker. Due to post-harvest-process variations, the obtained results assist in authenticating the chemical compounds of Robusta Java Bogor green beans.

White tea is a plant-derived product from Camellia sinensis L, which is processed without enzymatic oxidation and fermentation. The high identity traits (HITS) is a sensory evaluation method that identifies dominant attributes using five attributes to describe each sample. The sensory evaluation research on white tea uses the HITS method with an environmental approach aimed at identifying dominant attributes of white tea using both trained and untrained panelists, as well as at determining the intensity of these dominant attributes using an environmental approach with both trained and untrained panelists. The materials used were five samples of Gamboeng white tea, Heizl, Dandang, Pucuk, and Ennie1. The HITS method with trained panelists successfully identified dominant attributes as follows: yellow-brown brew color, rose aroma, rose flavor, astringent aftertaste, and light mouthfeel. Meanwhile, the experiment using untrained panelists showed dominant attributes as follows: yellow-brown brew color, jasmine aroma, jasmine flavor, astringent aftertaste, and light mouthfeel. The HITS method with an immersive approach for both trained and untrained panelists had an impact on increasing the intensity of aroma, flavor, and mouthfeel while decreasing the intensity of aftertaste.

Consumption of honey has increased in recent years. This included trigona honey as a new market that is developing. This research was conducted to (1) identify the consumption patterns for Indonesian honey, and (2) identify the sensory attributes of honey considered ideal by consumers which influence consumer acceptance and satisfaction. There were 2 stages of activity in this study, including a consumption online survey by 225 respondents and a sensory testing of honey samples using the CATA (check-all-thatapply) method involving 64 untrained panelists. Data analysis was carried out using SPSS and XLSTAT 2022 software. There were 4 honey samples used in this study: 2 Apis bee honey samples and 2 trigona honey samples. The study showed that the consumption pattern of Indonesian honey consumers is influenced by the consumers' age and income. Health benefits, brand awareness, and taste of honey were the important factors in consumer behavior. Apis bee honeys were perceived as the ideal honey by consumers as they were very familiar with the taste. The sweet aroma, sweet aftertaste, caramel flavor, and viscous attributes of Apis bee honey were the attributes that the consumers like. The floral flavor and fruity aroma found in trigona honey were appealing. However, the strong sour aroma, taste, and aftertaste found in trigona honeys decrease the Indonesian consumers liking.

Cassava (Manihot esculenta) can be used as the main source of carbohydrates besides rice. Although cassava has been widely used, the diversification of cassava is limited. Appropriate processing methods are needed so that the nutrition value of cassava can be maintained and safe for consumption. This study aimed to evaluate the nutrition value of frozen cassava fries through proximate, minerals, cyanide content, and trans fatty acids analysis and to assess the physical quality, such as color and texture. The best-frozen cassava fries processing methods obtained were steaming 100°C for 25 minutes and deep frying 180°C for 45 seconds. The results showed that color analysis L (tingkat kecerahan), a* (koordinat kromatisitas), and b* (koordinat kromatisitas), were 70.39±0.98, -2.11±0.72, and 28.06±1.06. The levels of protein, fat, and carbohydrates were 1.14±0.271 g/100g, 12.18±0.017 g/100g, dan 35.80±0.023 g/100g. The levels of Ca, Mg, and Fe were 274.047±7.42 mg/100g, 17.3±0.31 mg/100g, dan 4.59±0.26 mg/100g. The cyanide level decreased to 2.602±0.00 mg/kg from 75.458±0.00 mg/kg. In all frying treatments, trans fatty acids were not detected. In conclusion, frozen cassava fries have potential as a healthy diet component. [ABSTRACT FROM AUTHOR]

Sweetener as a food additive which gives sweet taste has a different profile from sucrose. Intensity profile and attribute sensation become very useful in developing mixed sweeteners from single sweeteners to create commercial sweeteners having a sucrose-like profile. However, there is only few data of attribute intensity and descriptive profiles of single sweeteners. The aim of this research was to analyze the descriptive profile of single and mixed sweeteners using quantitative descriptive analysis (QDA), time intensity (TI), and temporal dominance of sensations (TDS) methods. The results of QDA descriptive profile showed that samples of a single sweetener T3 as well as mixed sweetener containing C2 and C5 had the same characteristics as sucrose. The results of TI descriptive profiles showed that the time intensity curves of sweet attribute of a sample of two mixed sweeteners C1 and C2, and a single sweetener T3 were similar to that of sucrose. The results of the descriptive profile using TDS methods generally showed that the dominant attributes of all samples were sweet, sweet aftertaste, and licorice. Bitter and bitter aftertaste attributes were found in single sweetener T7, while mixed sweetener C1 had best sensory characteristics than the others. [ABSTRACT FROM AUTHOR]

Tea is one of the most widely consumed beverages in the world. Different types of tea provide different sensory profiles. The present study aimed to evaluate sensory characteristics of green tea by analytical sensory evaluations through QDA (Quantitative Descriptive Analysis) and CATA (Check-All-That-Apply) methods. The sensory characteristics of green tea from three different countries (China, Thailand and Indonesia) were evaluated using QDA by trained panels and CATA by consumer panels. The QDA method revealed sensory characteristics of green tea, while CATA method presented information on consumer preferences towards the most desirable characteristics of green tea. The results showed that green tea has dominant characteristics of bitter taste, astringent aftertaste, green flavor, fermented flavor and dry aroma. Moreover, floral aroma and flavor in green tea have considerable influences on the panelist preferences. However, "nice to have" attribute was not found in the penalty analysis. The "must have" attribute in green tea was floral aroma, while the "must not have" attributes were burned aroma, burned flavor and dry aroma. [ABSTRACT FROM AUTHOR]

Diabetes mellitus type-2 (DM-2) is a disease characterized by high level of blood glucose which may result in complications of other diseases. Currently, the disease prevalence of DM-2 has been increasing. Appropriate diet patterns can be a solution for DM-2 control. Black soybean milk (BSM) enriched with microencapsulated crude palm oil (CPO) is an example. The objective of the study was to determine the effectiveness of BSM containing microencapsulated CPO in controlling and improving the condition of DM- 2 patients. The intervention consist 2 group with 15 people DM-2 was given BSM 240 mL containing 0.4 g microencapsulated CPO daily for 28 days, while a control group with 11 people DM-2 without intervention product. Data were analyzed using software SPSS 15.0 with student-t test at significant level α=5%. Medicines prescribed to all volunteer were not terminated during the intervention period. The microencapsulated CPO usedin this study has a moisture content of 1.77±0.15%, solubility value of 65.39±2.71%, and total carotene of 295.24±7.40 ppm while BSM has protein content of 2.76±0.13%, fat 1.17±0.06%, ash 0.12±0.08%, moisture 94.69±0.04%, and carbohydrate (by difference) 1.27±0.10%. The consumption of BSM containing microencapsulated CPO showed insignificant effects on Fasting Blood Glucose (FBG) levels (P>0.05), but significantly reduced cyclooxygenase 2 levels (P<0.05) and MDA levels (P<0.05). The control group showed insignificant differences for FBG (P>0.05), cyclooxygenase 2 (P<0.05), and MDA level (P>0.05). The significant changes indicated that BSM containing microencapsulated CPO has against DM-2 disease. [ABSTRACT FROM AUTHOR]
