Using dry heat,moist heat,microwave,and extrusion to deal with fresh rice bran,then the impact of different methods on the residual peroxidase activity,the content of soluble protein,phytic acid,vitamin E and oryzanol,and the acid value and peroxide values in the long-term storage were compared.The results showed that:after extruded by moisture content of 30% and speed 600r/min at 130℃,the residual peroxidase activity was 4.8%,the content of vitamin E,phytic acid and oryzanol was respectively 3.65%,0.35%,7.0%,but the content of water-soluble ...
