Traditional and commercial soy sauces used for seasoning soups and cooked mungbean sprouts were evaluated for consumer preference. Table salt was included in sensory tests, because the consumer commonly used it for seasoning soups. Triangle tests with 30 trained panelists were used to evaluate differences between two soy sauces, and 9 point hedonic scale tests with 100 consumer panelists to evaluate the consumer preference. Taste of sea mustard, Chinese radish and dried pollack soups seasoned with the traditional soy sauce, commercial soy sauce for soup and table salt was significantly different. The consumer panel indicated that the commercial soy sauce for soup was most preferred and the traditional soy sauce least preferred. Taste of cooked mungbean sprouts seasoned with two sauces, prepared with either traditional or commercial soy sauces, was significantly different from each other, but the consumer panel could not detect the difference in preference.

The physicochemical and sensory characteristics of Kongnamulguk with commercial film-packed soy sprouts from domestic cultivars were investigated. The color determination showed that the solid part of Kongnamulguk had a light green color and did not change even when cooking for 9 minutes. The solid part of Kongnamulguk was much higher in insoluble dietary fiber than soluble dietary fiber. Soluble and insoluble dietary fiber of the soy sprout tended to increase upon cooking. The acceptability of the solid part of Kongnamulguk was negatively correlated with a bean odor and flavor, and a grassy odor and flavor, but positively correlated with a nutty odor and flavor. In addition, the acceptability of the liquid of Kongnamulguk was negatively correlated with a bean odor, a grassy and bitter flavor, while it was positively correlated with a sweet flavor. These results suggest that soy sprout with a less bean odor and flavor would be highly acceptable, so it would probably be suitable for Kongnamulguk.

Soy sprouts cultured in a lab with five soybean cultivars and three commercial soy sprouts purchased in a market were investigated to compare the mineral and vitamine contents. In case of minerals, K, Ca, Mg, and Na were found as major minerals and a small quantity of Fe, Zn, Mn, and Cu was also analyzed in soy sprout. The all minerals were distributed in the cotyledon and the hypocotyl but their concentration orders were different between in cotyledon and in hypocotyl. After boiling, much of minerals eluted in water, the pattern of release of the minerals from the soy sprout to water was similar in all soy sprouts. The vitamin C was concentrated a great amount in hypocotyl than in cotyledon whereas vitamin B was found in the cotyledon generally. And their contents were reduced after boiling owing to heat-mediated degrading. The vitamin C and B contents were different according to cultivars, which shows chemical composition of soybean seed was important to soy sprout characters. The present results provide a basis for attempt to improve seed quality in soybean breeding program for soy sprout.

This sudy was conductted for the purpose of determining the optimal amounts of soy tauce, soy bean paste and hot pepper paste, in 3 different Korean soups and comparing the effect of condiments such as salt, soy sauce, black pepper, and Mono Sodium Glutamate, on the taste of two basic Korean Stocks, The results estimated by Palatability Test were as follows: 1. The average NaCl contents of two kinds of commercial soysauce were 15.9%, 25.6%, respectively. 2. The NaCl contents of 2% sardine stock, and 19% beef stock were 0.16~1.17%, 0.17~0.18% respectively. 3. @ According to Saltiness in sardine stock, there was no difference between the soy sauce-added group and the salt-added group. However, for the removing effect of Off-flavor, and Overall Taste, the soy sauce-group had higher score than salt-added group respectively. (p>.0.1) ⓑ In beef stock, there was no difference between the soysauce-added group and the salt-added group in Saltiness test. The soy sauce-added group had higher score in removing effect of Off-flavor (p>.0.1). On other hand, in Overall Taste, the salt- added group was more effective than the soy sauce-added (p>.0.1). 4 @ According to Saltiness test in beef stock, there was no difference between the black pepper-added and non-added group. However, for the removing effect of Off-flavor and, Overall Taste, the added group had higher score than the non-added group, respectively. (p>.10, p>.0.5) ⓑ Also, according to Saltiness test in beef stock, there was no diffetrence between the MSG-added group and non-added group. However for the removing effect of Off-flavor, and Overall taste, the MSG-added group was more effective than the non-added group. (p>.01) 5. The best recipes of soybean sprouts soup for S persons, in this experiment, were soybean sprouts 180 g, sardine 28 g, soysauce 1/2 T.S., salt 7 g, green onion 15 g, choppedgarlic It. s., against 7 C of water, and total cooking time was 20 minutes. 6. The best recipes of clear-beef soup were beef 200 g, radish 200 g, tangle weed 10 g, sesame oil 1/2 t.s., green onion 15 g, chopped garlic 1 t.s., black Pepper 1/8 1.s., and soy sauce 1 T.S., salt 7 g or soy sauce 2 T S., salt 3.5 g. The total cooking time was minutes. 7, The best recipes of soybean pasted Chinese cabbage soup were Chinese cabbage 300 g, sardine 28 g, green onion 15 g, chopped garlic 1 t.s., and bean paste 50 g, hot pepper paste 13 g, salt 3g or bean paste 65 g, hot pepper paste 16 g, salt 1.5 g. And the total cooking time was 25 minutes. 8. Soy sauce, black pepper, M.S.G., bean paste and hot pepper paste were effective on removing Off-flavor of experimental soups.

We aimed to analyze the microbiological quality of the ready-to-eat (RTE) side dishes collected from traditional markets, supermarkets, and cafeterias in Gyeonggi-do in 2019. A total of 108 samples were analyzed for total aerobic bacterial counts, coliforms and foodborne pathogens depending on place of purchase and cooking methods. Results show that Bacillus cereus was detected in 14 (12.9%) out of 108 samples of side dishes, while no other foodborne pathogens were detected. The mean detected level (range) of total aerobic bacteria depending on place of purchase was 5.8 log CFU/g (3.0 to 8.2 log CFU/g) for traditional markets, 4.3 log CFU/g (2.4 to 7.8 log CFU/g) for supermarkets, and 3.80 log CFU/g (0.0 to 6.8 log CFU/g) for cafeterias, indicating that there was a significant (P<0.05) difference in total aerobic bacterial counts among places of purchase. Among the samples, the highest counts of total aerobic bacteria and coliforms were detected in saengchae (raw vegetables), followed by namul (seasoned herbs, vegetables), bokkeum (stir-fried foods), and jorim (foods cooked in soy sauce). The growth of total aerobic bacteria in seasoned soybean sprouts was inhibited when the sprouts were stored at 4℃ up to 24 h, whereas bacteria rapidly grew at 20 and 35℃ after 3 and 6 h, respectively. These results reveal that storage temperature might play a significant role for the microbiological quality of seasoned soybean sprouts when they are sold in markets. Thus, this study suggests that RTE side dishes should be stored at refrigerated temperature when being sold at markets as well as after purchasing to improve their microbiological quality.
