摘　　要：采用柚苷酶对橘红进行脱苦研究。以橘红脱苦率为指标,在单因素试验的基础上,采用响应面法优化柚皮苷酶对橘红的脱苦工艺,确定最佳脱苦条件为:酶解温度60℃、酶解时间2 h、酶用量为0.8%、pH值为4~5,在此条件下脱苦率可达25.1%。Pummelo Peel was debitterized by naringinase treatment.The response surface method was used for optimizing the conditions of debitterizing based on single factor experiment with the index of debitterizing rate.The results showed that the optimum conditions were as follows:enzyme treatment temperature was 60℃,enzyme treatment time was 2 h,enzyme dosage 0.8%,soaking solution pH was 4~5.Under this condition,the debitterizing rate reached 25.1%.
