The preparation of commercial, low-salinity kimchi needs to be carefully monitored to maintain the taste of kimchi. To address this, the taste profiles of three brands of commercial kimchi were examined using a taste sensing system, as well as a sensory evaluation. The average sensory score (4.3/9.0) in the overall taste of low-salinity kimchi (A', B', and C') was significantly lower than that (5.1/9.0) of conventional kimchi (A, B, and C). The explanation for the result of A' seemed to be its decrease in saltiness (3.51) and increase in bitterness (8.55) compared to those (6.55 and 7.65, respectively) of A. In B', the saltiness (4.25) and the overall taste (3.7) were significantly decreased compared to B (6.23 and 4.8, respectively). Interestingly, no significant difference was observed in the overall taste (5.1) and saltiness (6.70) of C' when compared to C (5.3 and 6.46, respectively), confirming that salinity is a crucial factor in determining overall taste. Consistent with this finding, the overall taste of low-salinity kimchi correlated positively with its saltiness (>0.98) and umami (>0.82). These results advocate the careful determination of salinity required to maintain the taste of conventional kimchi in preparing low-salinity kimchi, while also pointing towards the need to develop effective taste enhancers for supplementing overall taste.

Tartary buckwheat has established itself as a functional food source because of its basic nutrition and phenolic compound contents, such as dietary fiber (DF) and rutin (RU). However, little information has been obtained concerning the comparative effects of DF and RU on the in vitro and in vivo glucose responses of tartary buckwheat flour. Moreover, the relationship between the flour’s in vitro starch digestibility and its components’ blood glucose response is not well-known. This study found that DF and RU reduced rapidly digestible starch (RDS) by 37.32→33.88% and 41.71→30.28%, whereas they increased resistant starch (RS) by 30.47→31.46% and 28.41→36.78%, respectively. Furthermore, RU had a lower glycemic index (GI) compared to DF. The regression equation for the in vitro and in vivo data from RU exhibited positive correlation (R 2 = 0.99); however, DF did not display positive correlation, which indicates that the in vitro and in vivo GI mechanisms by DF and RU are different.

The aim of this study was to investigate the physicochemical characteristics of hand drip, Aeropress, espresso, Moka, Mukka, and Brikka coffee brews. Espresso showed higher antioxidant activity, total solids, caffeine, chlorogenic acid, total phenolic compounds, and trigonelline concentrations compared to the other coffee brews studied. In terms of extraction efficiency, Brikka and Mukka showed higher total solids, as well as caffeine and chlorogenic acid contents, whereas drip coffee brew showed higher trigonelline content than other coffee brews. Meanwhile, principle component analysis (PCA) was conducted based on the aroma profile by e-nose. Samples were gathered into distinct groups that represented their brewing methods. Despite the similarity in brewing principle between Moka and other high-temperature brewing methods (i.e., Mukka and Brikka), the location of Moka coffee brew was closer to that of espresso in PCA, which was consistent with the PCA result conducted by e-tongue.

This study aims to analyze the cooking and sensory characteristics of noodles to which different types and amounts of apples were added. Apple noodles were made by the addition of apple flour and apple concentrate to wheat flour in proportions of 0, 5, 10, 15, and 20%, respectively. Cooking time, weight after cooking, water loss after cooking, and rehydration rate were analyzed as cooking characteristics. Hardness, adhesiveness, cohesiveness, springiness, and chewiness were measured as texture characteristics, whereas sensory evaluation was performed on the appearance, color, taste, aroma, texture, and overall preference of noodles. The cooking time decreased as the amount of apple added increased, and the weight after cooking, water loss after cooking, and rehydration rate increased. The hardness and chewiness were decreased and the adhesiveness was increased as the amount of apple added was increased. The sensory test of apple noodles showed a higher score in taste and overall preference than that of the control. Furthermore, the addition of apples tended to produce a high score in all sensory tests, indicating that the addition of apples has a good effect on the quality of noodles. In particular, the addition of 10% apple concentrate showed high scores in all the tested characteristics.

The purpose of this study was to confirm changes in flavor and taste characteristics of black pepper by combining nonthermal sterilization treatment methods, namely intense pulsed light, cold plasma, and ultraviolet. After treatment, lightness value and hue angle of black pepper were decreased. The difference in chromaticity between samples before and after treatment showed a significant difference of 6.11. The piperine contents before and after the combined nonthermal sterilization treatment were reduced from 28.4±0.25 mg/g to 20.4±1.06 mg/g. The results of an intensity test showed that the color and flavor of the sample became darker and weaker, but hot and pungent were not distinguished after nonthermal treatment. The flavor profile showed that the intensity of cool flavor was decreased, the intensity of nutty taste was increased, and other sensory languages did not show any difference. Although differences in flavor and taste were distinguished in a cooking application, the differences were not significant.

In this study, a controlled atmosphere (CA) storage system is proposed as a storage method for prolonging processing period. Persimmon was placed in CA storage at 0.5oC±0.5 for 92 d. The qualities of the stored persimmons were compared to determine the possibility of extending shelf life. ‘Sangjudungsi,’ which was harvested on October 26, 2017, was applied to the persimmons. In order to compare differences according to size, the persimmons were classified into Size No. 2 (170 g) and Size No. 3 (145 g). In the result, the yellowness of CA-stored persimmons was 26.3% lower than that of cold-stored ones, confirming that after-ripening was delayed. The firmness of CAstored and Size No. 3 persimmon was higher than that of cold-stored and Size No. 2 persimmon. Tannin decreased significantly in cold storage, but it tended to increase in CA storage. The sugar content of Size No. 3 was lower than that of Size No. 2, but there was no difference in tendencies according to the storage method. Weight loss in CA storage was lower than that in cold storage. A comparison of color difference, firmness, sugar content, tannin, and weight loss ratio showed that CA storage was more effective in improving shelf life than cold storage.

The objective of this study is to determine the effects of barrel temperature and moisture content on the physicochemical properties of texturized vegetable protein (TVP). The water absorption index, water solubility index, texture, integrity index, color, and scanning electron micrograph of the TVP were analyzed. The extrusion conditions consisted of barrel temperature (110, 130, and 150oC) and moisture content (40, 45, and 50%) at a fixed screw speed of 250 rpm. The TVP extruded at 150oC barrel temperature and bearing 50% moisture content had higher water absorption index and water solubility index. Elastic force, cohesiveness, and color differences were the highest in the TVP extruded at 150oC barrel temperature and possessing 40% moisture content. However, the TVP at 150oC barrel temperature and having 40% moisture content had a lower integrity index than the TVP carrying moisture contents of 45 and 50%. The structure of the TVP extruded at 150oC barrel temperature and having 40% moisture content was found similar to a chicken breast tissue’s structure. In conclusion, 150oC barrel temperature and 40% moisture content are optimal conditional characteristics for the texturization of soy protein isolate and gluten.
