The Study on the Oxidative Stability of Mixed Rapeseed oil with Palm oil
팜유 혼합유채유의 산화안정성에 관한 연구
Abstract
Two kinds of simple and interesterfying mixed rapeseed oil were prepared according to add 30%, 50% and 70% of coconut and palm oil, then the physicochemical propecties such as the tedency of oxidation, foaming activity were Investigated. The initial AV and POV of interesterifyung mixed rape-seed oils were higher than those of simple mixed oils, but the tendencies of oxidation were similar. The intial value of IV interesterfied rapeseed oils was added in simple mixed rapeseed oil, Induction period were increased about 2.4~4 times. Induction period of intereterifyng mixed oils added palm ell increased about 2~3.2 times. While the foaming Buantity of interesterifing mixed rapeseed oils with palm oil were lower about 28~40% than those of the simple mixed rapeseed oils.
Erotic acid함량이 높은 유채유(HEAR oil)와 erotic acid함량이 낮은 유채유(LEAR oil)에 대하여 팜유를 각각 30%, 50%, 70%의 비율로 단순혼합한 유채유와 ester 교환 혼합유채유를 제조하였다. 이들 혼합유채유의 혼합비율, 혼합방법을 달리한 때의 산화안정성을 알아보기 위하여 항온저장시(
