  • This study estimated the isoflavone intake level in Koreans using Food Frequency Questionnaire and analyzed related variables. The results showed that the average daily intake of isoflavone in adults was shown as 23.1 mg. The isoflavone intake level at 50 percentile was 16.9 mg ($0{\sim}90\;mg$), and 10% of adults took almost 50 mg of isoflavone a day and 10% took about 5 mg a day. The major food sources for isoflavone in Koreans were in the order of soybean, soybean paste, soy milk, soybean curd (tofu), and bean sprouts; the intake was different depending on age, educational background, occupation, economic standard, and family type. The result showed higher isoflavone intake levels in the group over 30 years old and the highest isoflavone intake in subjects working in farming/fishery, followed by housemakers. According to the differences by families the families with elderly members showed 50% higher isoflavone intake than young families with friends or siblings. Depending on related ecological variables, therefore, various nutrition education programs should be developed for a variety of intakes of soybean foods, along with easy and simple cooking methods as parts of continuous research.

  • The objective of this study was to develop remedies to improve sanitary quality of school meals. To analyze the usage of potentially hazardous foods, menus from 180 school foodservice establishments were collected through school websites. Statistical analyses were conducted using the SPSS package program (ver. 20.0). The results of this study are as follows: analysis of the foodservice production process revealed that the following were employed: heating process (70.5%), non-heating process (16.3%), and after-heating process (13.2%). In addition, the cooking methods used for side dishes were: stir-frying (22.1%), saengchae (21.3%), sukchae (15.2%), jorim (12.4%), deep-frying (10.2%), and grilling (9.5%). Overall, 64 menu items known to pose potential microbiological hazards were offered a total of 2,671 times. The usage frequency was high for bibimbap, pork-bulgogi, cucumber-saenchae, seasoned bean sprouts namul, seasoned spinach-namul, and korean cabbage-geotjeori. In conclusion, in order to increase the sanitary quality of school meals, menus or foods that contain microbiological hazards should prepared very carefully with respect to time and temperature management during food production. Also, school foodservice employees must possess proper food safety knowledge and techniques for applying the HACCP system to prevent foodborne illness.

  • The purpose of this study was to find the level of satisfaction and preferences regarding the mess provisions in the three military bases in Daegu, Korea. A total of 325 military personnel was surveyed for this study. The content of examinations consisted of the general characteristics, satisfaction, awareness, and preference for the mess. Furthermore, I investigated the general menu on a daily basis with the most or the least-preferred food. As a result, I found that fried dishes are most preferred by military personnel, and they second and third in their preferences are boiled, and mixed with dressing. I also found that military personnel like meat, sweets like ice-cream, fried pork chops or chicken, and fatty and processed food like hamburgers. On the other hand, they do not like dishes made with bean sprouts, squid, fish or kimchi. On the basis of the results, a balanced diet is needed for military personnel through the research and development of recipes using some of the least favorite ingredients such as fish, squid, and vegetables.

  • This paper describes a naturally occurring case of meningoencephalitis associated with Listeria monocytogenes in a 4 month-old Korean native goat. The goat was raised in a herd consisting of seventy goats, and fed on straw and leftover vegetables including onions, cauliflower, and bean sprouts. The clinical symptoms of the goat were depression, in appetence, anorexia, circling, and recumbency before death. No conspicuous gross lesions were found except consolidation of the lung. Histopathologically, severe multifocal microabscesses and perivascular cuffings were observed in the brain stem and mid brain. In addition, mild nonsuppurative meningitis in the cerebrum were seen in this case. The organism isolated from the brain stem was confirmed as L. monocytogenes using the biochemical tests and PCR assay. Based on clinical signs, histopathology, and bacterial isolation; we confirmed that this case was a typical encephalitic listeriosis.

  • The purpose of this study was to investigate the Jorim of meat and poultry in Korean modern cookbooks. Jorim is a traditional Korean method of braising meat and poultry with soy sauce or gochujang. This study evaluated jorim in 10 books published in Korea from the end of 1800 to 1987 and to develop cooking models of beef jorim, pork jorim, and chicken jorim. The main ingredients in the jorim were beef, pork, chicken and pheasant. Other ingredients in the jorim included pine nuts, beef, eggs, radishes, bean sprouts, onions, bamboo shoots and pepper. In Sieuijeanseo, which was published at the end of the nineteenth century, the method called for braising meat directly in soy sauce. However, other modern cookbooks suggested boiling the meat prior to braising. Despite jorim being a popular sub-dish in Korea, there has been a decrease in the varieties available.

  • The cultivation period of mung beans (Vigna radiata L.) in Korea has undergone recent variations. However, limited research has been conducted on pod shattering and sprout characteristics of mung beans on different sowing dates. This study aims to compare pod shattering and sprouts productivity based on different sowing dates. The research was was conducted with six different sowing dates (early May, mid-May, early June, mid-June, early July, and mid-July) in 2021 and 2022. Delayed sowing dates resulted in shortened days to germination, flowering time, and maturity time, whereas plant height, branch number, and node number increased. In addition, stem thickness and the number of pods per plant decreased. In the mung bean cultivar 'Sanpo', the pod shattering rate ranged from 10.0% to 19.3%, consistently lower than that of 'Dahyun' across all six sowing dates. The sowing date associated with the lowest shattering rate was early June. 'Sanpo' sown in early July and 'Dahyun' sown in mid-May exhibited the highest sprout production, at 871% and 750%, respectively.

  • The changes of growth characteristics and antioxidant activity for selection of optimum germinated temperature on common bean (Phaseolus vulgaris L.). Common beans (IT100888, IT102849, and IT231267) were cultivated at $20^{\circ}C$, $23^{\circ}C$ and $25^{\circ}C$ during 5 days of germination. The range of whole length, hypocotyls length, thickness, abnormal germination and yield rate of sprouts was 7.27~27.62 cm, 3.10~18.86 cm, 1.80~2.27 mm, 5.54~18.34% and 205.95~ 618.71%, respectively. Antioxidant activities of common beans with germination temperature investigated. Common beans (IT100888, IT102849, and IT231267) germinated at $20^{\circ}C$, $23^{\circ}C$ and $25^{\circ}C$ during 5 days, and then extracted with 80% ethanol, and analyzed for total polyphenol content, DPPH and ABTS radical scavenging activity. Total polyphenol content increased from 474 mg GA eq/100 g sample for IT231267 to 1364 mg GA eq/g sample for $23^{\circ}C$ of germination. DPPH radical scavenging activity of IT102849 increased from 189mg Trolox eq./100 g sample ($20^{\circ}C$) to 1073mg Trolox eq./100 g sample ($23^{\circ}C$) also ABTS radical scavenging activity of IT234267 increased from 479 mg Trolox eq./100 g sample ($20^{\circ}C$) to 1134 mg AA eq/100 g ($23^{\circ}C$). These results suggest that germination temperature for increasing antioxidant activities may be $23^{\circ}C$.

  • The purpose of this study was to investigate the effect of thermal treatments, such as a sous-vide and a conventional hot water cooking, on the texture changes of soybean sprout. A novel method to measure texture properties of soybean sprout have been determined because of the irregular geometry of soybean sprout. The shape of cotyledon of bean spout was accurately analyzed using an image processing and a geometry model. To minimize the effect of the contact area on the texture measurement, a blade type of probe was selected for the measurement. True stress was evaluated to reflect the shape changes during deformation, and demonstrated that the measurement accurately distinguished the effect of thermal treatment on the texture. Different heating time (i.e., 0, 10, 20, and 30 min) was applied for both sous-vide and conventional cooking. Thermal processing caused hardening of textures for both cotyledon and hypocotyl of soybean sprout. The conventional cooking method showed higher stress values than those of sous-vide cooking. Sprouts cooked by sous-vide released the moisture after thermal processing while sprout cooked by a conventional water bath method could hold the moisture content during thermal processing. The soybean sprouts treated by conventional cooking method showed a higher score in sensory evaluation.
