Abstract
To explore why the ratio of collectable wort extract is higher than that of non-extruded,the influences of all parameters of rice extrusion system(barrel temperature,material moisture,screw speed) on resistant starch content of extuded rice were studied by using second-order quadratic orthogonal rotating combination design method.The research results indicate that the resistant starch of extruded rice adjunct was 0.27% and 6.17% less than that of tradition cooking method and raw grain rice respectively.
