摘要
采取酶解法辅助水蒸汽蒸馏法提取桔皮中精油,探索了纤维素酶用量、酶解处理时间、酶解温度、蒸馏时间等工艺条件对桔皮中精油提取率的影响。通过正交实验,酶解-水蒸汽蒸馏法提取桔皮中精油的最佳条件为:酶用量是2000 U/g,酶解温度是55℃,酶解时间是140 min,蒸馏时间是2 h。采用此工艺条件,桔皮中精油的提取率是3.14%。
Extracted essential oil from orange peel by enzymatic auxiliary steam distillation, the rate of enzymatic hydrolysis of cellulase dosage, treatment time, hydrolysis temperature, time of distillation process conditions on the extraction of essential oil from orange peel. Through orthogonal experiments, the best conditions for enzymolysis auxiliary steam distillation extraction of essential oil from orange peel： enzyme dosage is 2 000 U/g, enzymolysis temperature is 55 ℃, enzymolysis time is 140min, extraction time is 2 h. Under such conditions, the extraction rate of orange peel oil is 3.14%.
