In this study the effect of rice type and cooking methods on the quality of cooked rice during cold storage wereinvestigated to develop home meal replacement (HMR) products. The chemical and physical properties and sensoryquality of rice were studied by rice type (Oh-dae-mi, Baek-jin-ju S., and Indica) and cooking methods (electric ricecooker and super heated steamer). Cooked rice was stored at 5oC for 3 days and the moisture content, color, reduc-ing sugar content, texture profile, and sensory evaluation were analyzed. The results show that rice type Baek-jin-ju S. has the highest moisture content and that color and textural properties are maintained during storage. Ricecooked with an electric rice cooker has higher moisture content and better color properties; however, rice cookedwith a super heated steamer shows higher reduced sugar content with a softer texture. The selection of Baek-jin-juS. and cooking with a super heated steamer have a positive effect on the quality of rice during cold storage.

Marinated beef galbi is a traditional Korean dish cooked with soy sauce, pear juice, onion, sesame oil, and sugar. However, there are many differences in beef galbi, including flavor and physicochemical aspects, depending on cooking conditions. Therefore, the physicochemical characteristics of marinated beef galbi prepared through various recipes was evaluated for its effects on pH, texture, aging, proteolysis, heating conditions, cooking time, and flavor compounds (pyrazines, IMPs, or FAAs). There were significant differences in salt concentration (0.8~3.03%), pH (4.89~6.22), and solid soluble contents (1.34-6.31 Brix) between recipes in this study. In the Pearson assay for sensory evaluation, overall preference correlated well with texture (a well-known sensory attribute in meat evaluation). Controlling the pH of meat through soaking in lemon solution, alkali water, phosphate, and baking powder solution, improved water holding capacity as much as 9 to 15% compared with the control. The myofibril index (MFI) of marinated meat stored at 4℃ increased 32% with 24 hours of aging and reached 39% at 48 hours of aging, and its fragmentation was observed through microscopy. SDS-PAGE showed hydrolysis of acid-soluble collagen by the pear juice, possibly related to meat tenderness. On the basis of surface temperature, the cooking time was estimated to be 8 minutes with pan heating at 170℃, 6 minutes at 270~300℃, and 4 minutes with charcoal at 700~900℃. Different pyrazine compounds, such as 2-methyl-3-phenylpyrrol(2,3-b) pyrazine (the typical product of the browning reaction) was mainly detected, and IMP (one of the main taste compounds in beef) was in higher amounts with the charcoal treatment, potentially related to its flavor preference among treatments. Our results demonstrate an effective case study and cooking system for beef galbi.

This study was conducted to investigate performance of methods for cooking and thawing frozen cooked rice to retard retro-gradation of cooked rice. For this research, That was executed rice's physicochemical and sensory characteristics test through the way of boiling rice or thawing, and found out best way for retro-gradation and taste. This study showed the rice cooked by pressure rice pot has less dehydration during freezing and thawing, and thawed rice by micro wave has less dehydration. Repetition of freezing and thawing resulted increasing of hardness and chewiness, and decreasing of adhesiveness and cohesiveness. The rice cooked by convotherm oven or pressure rice pot has less increased hardness while freezing and thawing. Adhesiveness was superior when rice was cooked by pressure rice pot. The rice thawed by microwave had more hardness than thawed in room temperature.

우리의 식탁에 사용 빈도가 높은 강낭콩조림을 선정하여 전통적으로 조리되는 과정과 재료의 혼합비를 파악하고 보존 hurdle로서 가열조리조건을 조절하여 강낭콩조림의 저장 안전성을 향상시키고자 하였다. 강낭콩 150g 기준에서 설탕 40g, 간장 30g, 물엿 30g인 배합비 하에서 가열조리시간을 25-50분으로 달리하여 조리하여 제품을 가공한 다음, 에서 20일간 저장 중 품질 변화를 측정하였다. 장시간의 가열조리인 50분 가열에서는 저장 10일째

콩의 증자조건에 따른 검정콩 전통간장의 숙성 후 유리당, 유기산, 지방산조성을 조사하였다. pH 값은 5.04～5.32로 시험구간의 큰 차이를 나타내지 않았고, 원료 콩을 상압증자한 검정콩 간장이 가압이나 스팀보다는 약간 높은 수치를 나타내었다. 적정산도는 4.26～7.72 mL로 나타났으며, 가압 증자한 검정콩 간장(4.26～5.61 mL)이 가장 높았으며, 다음으로 상압(7.32 mL), 스팀(5.99～6.96 mL)의 순으로 나타났다. 환원

검정콩을 이용한 기능성 간장을 제조하기 위한 연구의 일환으로 원료 콩의 증자조건에 따른 검정콩 전통간장의 숙성후, 질소화합물 및 유리아미노산의 함량을 조사하였다. 총질소 함량은 308.3∼925.0 mg%로 나타났으며, 상압이나 스팀에 비하여 가압으로 증자한 간장의 총질소 함량이 아주 낮았고, 스팀증자 시간이 길어짐에 따라 총질소 함량이 증가하였다 아미노태질소 함량은 133∼451.5 mg%로 나타났으며, 상압(451.5 mg%)이 가장 높았으며
