中文摘要: 以火龙果皮干粉为原料，采用超声波-纤维素酶法辅助乙醇提取火龙果色素，通过单因素试验和正交试验考察纤维酶添加量、乙醇浓度、超声功率和提取时间对红龙果皮中的色素甜菜红素提取率的影响。结果表明最佳提取工艺条件为：纤维酶添加量为1%、乙醇浓度为30%、超声功率50 W和提取时间20 min，在此条件下火龙果皮中的甜菜红素提取率达70.06%，制备的火龙果皮色素粉末的色价为2.071。
Abstract:Ultrasonic-enzymatic hydrolysis assisted extraction process of pigment from pitaya peel was optimized by single factor and orthogonal experiment method.The effects of fibrinase addition，alcohol concentration，ultrasound power and extraction time on the extraction yield were investigated.The results showed that the optimized extraction conditions were：fibrinase addition 1%，alcohol concentration of 30%，ultrasonic power of 50 W and extracted for 20 min.Under this condition，the extraction rate reached to 70.06%，the color price of thepitaya pigment powder was 2.071.
