| Abstract: | Rice wine grains stillage is abundant low value protein resources in China and through enzymic extraction high value products could be got.Through single factor and orthogonal experiment the optimum conditions for enzymic extraction of protein were determined and they were: enzyme dosage 2%,temperature 65 ℃,the ratio of stuff to water 1∶10,pH 8.5 and reaction time 240 min.Under these conditions,the protein extraction rate was 72.25%. |
