Effect of microwave pre-treatment of oilseeds on oil quality

Abstract

The effect of microwave heating on quality of oil from different oilseeds was investigated. It was demonstrated increasing of pressing oil input almost by 40 % in case of microwave pretreatment and we have observed the similar effect of microwave pretreatment on quantity of oil extracted by hexane. The quantity of extracted oil was almost 50 % higher comparatively with conventional pretreatment. It was shown that oil obtained after microwave pretreatment of seeds was differing from control oil (after conventional heating). The both sample had almost the same acidity but oil after microwave pretreatment had lower peroxide value.
