Abstract: Corn gluten meal(CGM) consists of plenty corn-yellow pigment. However, the extraction of the pigment require a long extraction time. The experiment studied the optimum technology conditions by microwave and enzymolysis from CGM with single factor tests and orthogonal tests. The results showed that the optimum extraction conditions are: microwave output power 450 W, microwave radiation time 35 s and the ratio of solid to liquid 1:10 with 95% ethanol, substrate concentration 5%, enzyme density 1.4% and enzymolysis time 6 h.

Key words: microwave, enzymolysis, corn-yellow pigment
