【摘要】 以新疆石榴原汁为材料,在单因素试验的基础上,通过正交试验筛选果胶酶澄清石榴汁的工艺条件。结果表明,果胶酶澄清石榴汁最佳工艺为:果胶酶添加量64.32 U/100 m L,酶解时间35 min,酶解温度45℃,经该工艺条件澄清后石榴汁的透光率为91.39%,花色苷含量为89.74 mg/100 g。更多还原

【Abstract】 The clarification conditions of pomegranate juice from Xinjiang using pectinase were optimized by the single factor and orthogonal tests. The results showed that, the best technologies of pectinase for clarifing pomegranate juice were:adding amount of pectinase 64.32 U/100 m L, enzymolysis time 35 min, enzymolysis temperature 45 ℃. The light transmittance of the clarified pomegranate juice was 91.39%, and anthocyanins content was 89.74 mg/100 g.更多还原
