摘　　要：通过温度、时间、果胶酶用量、溶剂流量为因素的正交试验,研究果胶酶对胡萝卜可溶性固形物连续逆流浸取浸汁的影响,以浸汁浓度与浸取率为参数优选最佳浸提工艺。结果表明:添加果胶酶后浸汁浓度和浸取率都有明显提高,在50℃条件下,果胶酶用量300μL/L,溶剂流量10L/h,浸提时间55min,浸取率为88.3%;在50℃条件下,果胶酶添加量300μL/L,溶剂流量6L/h,浸提31min,浸汁浓度为4.5°Brix。Throughout the orthogonal experiments of temperature, time, content of peetinase and the solvent flow, the effect of the pectinase to the carrot soluble solid content was studied the optimum extraction technology was obtained. The results showed that the extracting density and the extracting efficiency were both obviously approved in addition of the pectinase. The extracting efficiency could be 88.3 % when 50 %, 10 L/h, the pectinase content 300 uL/L and the extracting time 55 min. The extracting density could be 4.5°Brix when 50℃, 6 L/h, the pectinase content 300 uL/L and the extracting time 31 min.
