에탄올-물과 메탄올-물 혼합용매를 이용한 대두 추출물의 항산화 효과

Abstract

본 논문은 에탄올-물과 메탄올-물 혼합 용매를 이용한 대두 추출물의 항산화 효과를 연구한 논문으로 주요내용으로는 용매추출물의 고형분 수율과 대두추출물들의 대두유 및 난황 레시틴 리포좀의 산화에 대한 항산화성을 근거로 대두를 볶아주고 의 메탄올용매로 추출하는 방법으로 항상화제를 추출하였으며 탈지대두박도 좋은 원료임을 확인할 수 있다는 내용이다.

The effective extraction of antioxidative substances from soybeans was studied by the mixed solvents of methanol or ethanol with water at 30°C and 85°C. At accelerated peroxidation condition, POV (peroxide value) of soybean oil and TBARS (thiobarbituric acid reactive substances) value of egg yolk liposome with extracts added, were applied for the evaluation of antioxidative activity of the extracts. In the peroxidation of soybean oil, antioxidative substance of soybeans was extracted more effectively by methanol and at higher temperature 85°C, and the deffated and roasted soybean extract (DRS) showed higher antioxidative activity. But in the Peroxidation of egg yolk liposome, methanol extract from the roasted soybeans (ROS) showed higher activity.
