摘　　要：研究了果胶酶和硅藻土联合澄清荔枝果汁的作用和效果。在单因素分析的基础上,通过正交试验优化得到澄清工艺的最佳条件为:果胶酶用量为5mg/L、pH5、澄清时间5.5h、温度50℃、硅藻土用量4g/L。在此最佳工艺条件下,荔树果汁的澄清效果和贮存稳定性均良好。The effect and result of clarifying litchi juice with pectase and diatomite were studied. Based on single-factor analysis and through orthogonal experiments,the optimal parameters of clarification were determined as： pectase 5 mg/L,pH 5,5.5 h, 50℃ and diatomite 4 g/L. Under the optimal conditions,both the clarification result and storage stability of the juice were satisfactory.
