Comparison on Extraction Yield and Quality of Coix Seed Oil
The effects of four types of extraction methods on the yield and the quality of coix seed oil were investigated. The extraction yields (EYs) by these methods were: 3.43% (Microwave-assisted extraction, MAE); 2.13% (Ultrasound-assisted extraction, UAE); 1.72% (Aqueous enzymatic extraction, AEE) and 1.29% (Refluxing extraction, RE) respectively. Both the peroxide number and acid value by RE are the highest, while by other methods are almost the same.
