Analysis of Rice Bran Oil Adulterated with other Edible Oils by GC

Abstract

Since rice bran oil (RBO) is well-known by consumer and more expensive than other oils, some RBO is adulterated with other cheap oils, such as cottonseed oil (CO), palm oil (PO), sunflower oil (SFO) and soybean oil (SO). The types and content of FAs in RBO changes great after adulterated, this will seriously affect the quality of the rice and the people health. In this study, GC was used to detect the change of fatty acids (FAs) after adulterated with those inferior oils. The analysis will provide a reference for the RBO adulteration problem.
