귀리를 건강 및 기능성 식품소재로서 개발하기 위하여 귀리 겉겨(OBC)로부터 수용성 -glucan을 중심합성실험계획에 의해 분리하고, 생물활성(항균, 항산화, 암세포 생육저해능)을 검토하였다 귀리 수용성 -glucan 시료는 250, 500/disc농도에서 항균활성을 paper disc method로 검토한 결과 항균력이 없었으며, 5%농도에서 전자공여능(electron donating ability, EDA)으로 측정한 항산화활성도 없었다. 귀

본 연구는 콩국수용 즉석 콩스프를 개발하기 위하여 콩스프 가공을 위한 최적 조건을 검토하였다. 콩스프 가공은 원료 침지, 증숙, 탈피, 건조, 분쇄, 제품포장의 순으로 하였다. 최적 콩 침지조건은 에서 4시간이었고, 이때 단백질의 함량은 노란콩 21.97%, 검정콩 19.88%이었다. 증숙처리시간이 길어짐에 따라 수분함량에는 큰 변화가 없었으며, 10에서 15분간 증숙처리한 것이 관능검사에서 가장 양호하였다. 열풍건조시 노란콩과 검정콩의 단백질

The effect of irradiation of heat treatment either alone or in combination on the shelf-life of mixed mountain edible herb drinks (MMEHD) was investigated during storage. The MMEHD made from fresh Spuriopinella bracycarpar, Ligularia fischeri and Aster scaber was gamma -irradiated at doses of 0.1 kGy to 1 kGy. Microbial population, color change, vitamin C content, and sensory quality were evaluated during storage at 4, 25 and 35oC. Heated MMEHD induced the growth of total counts, mold and yeast as compared to the non-heated MMEHD. While some reduction in the microbial growth was observed in 1kGy-irradiated groups of both with or without heating. In both groups, L and b values decreased, but a value increased during storage. Also, heating drinks showed increased L and b values and reduced a value, compared to the non-heating drinks. Non-heated drinks showed 82% loss of vitamin C, whereas 25% loss of vitamin C was occurred in the irradiated drinks during storage at 4oC for 4days. In the meanwhile, non-irradiated heating drinks showed 99% loss of vitamin C, but irradiated heating drinks showed 58-65% reduction of vitamin C. Non-irradiated drinks without heating showed more bright color than irradiated ones, but irradiated drinks showed more enhanced brightness during storage. Also, irradiated drinks showed better falvor, sensory quality, and overall acceptability than non-irradiated drinks.
