Abstract
New method of microwave extraction of corn pigment extraction was studied and the pigment stability was investigated.The optimal conditions were determined as follows: microwave power was 360 W,extraction time was 90 s,the concentration of extraction agent was 70%,the ratio of material weight to extraction agent volume was 1∶8;the effects of acid,alkali and heat on stability of the corn yellow pigment were high while the effect of light on stability of it was low;the effects of food additives: sucrose and citric acid were high and the effects of Vitamin C and sodium benzoate were low;Antioxidant property of the corn yellow pigment was high but anti-reductive property of it was low.
