Low protein and phosphorus rice flour was prepared by alkaline protease using rice as raw material and protein residual rate and phosphorus residual rate as evaluation indexes.The effect of each factor on the result was optimized by single factor experiment and orthogonai experiment.Resuits showed that the optimal condition was temperature 55 ℃,alkaline protease addition 1.2％,time 9 h,pH 10.0,solid-liquid ratio 1∶6 （g∶ml）.Under this condition,the protein residual rate wa...
