桑汁二次沉淀原因及净化方法研究

Study on Re-Precipitation Cause and Removing Methed for Mulberry Juice

探讨了桑叶浸提汁二次沉淀物的主要组成,筛选了适宜的处理方法。结果表明:桑叶浸提汁在贮存过程中产生的沉淀主要由蛋白质、单宁和灰分组成。采用0.30‰膨润土净化处理,温度50℃、时间45min可有效地防止桑汁二次沉淀的形成。

The re-precipitation cause and removing method for mulberry juice were studied.The results showed that precipitatesduring storage of mulberry juice were protein,tannin and ash.If bentonite was used to eliminate sediment,the optimum conditionswere 0.30‰ bentonite,50℃ and 45min.
