摘要
黄酒糟是我国丰富的低值蛋白资源,通过蛋白酶法提取可获得高附加值产品。通过单因素试验和正交试验,确定了碱性蛋白酶提取黄酒糟蛋白的最佳工艺条件,即:加酶量2.0%,温度65℃,料液比1∶10,pH值8.5,反应时间240 min。此工艺下蛋白提取率为72.25%。
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%.
