摘　　要：以干橘皮粉为原料,对橘皮油溶性色素的提取工艺进行研究。结果表明,其最佳提取工艺条件是:以pH3.5的稀盐酸为酸解液,按料液比为1:10(w/V)的比例投料,在80℃下酸解2h,将滤渣烘干,加入0.8%(以底物质量计)果胶酶,按料液比1:11(w/V)添加pH4的盐酸,在50℃水浴下水解80min,将滤渣烘干,以石油醚为浸提剂,按料液比1:12(w/V)的比例投料,在25℃下浸提7h,重复浸提3次。油溶性色素得率1.8%。Liposoluble pigment in tangerine peel is a dark yellow-brown ointment with its maximum absorbance of 330rim by UV-spectrophotometer. In this paper, extraction of liposoluble pigment from dry powder of tangerine peel was studied. The best acid hyrolysis conditions were determined as follows： hydrochloric acid （pH 3.5） as acid solution, ratio of acid solution to the dry powder of tangerine peel of 1：10 （V/W）, hydrolysis time of 2h an temperature of 80℃. Then the residues were dried for further treatment. For the following enzymatic hydrolysis progress, the best pectic enzyme dosage, ratio of dried extracts to acid solution （pH 4）, extraction temperature and lime were 0.8%, 1：11, 50 ℃ and 80min, respectively. The achieved residues was further dried and extracted by oil aether with solid-liquid ratio of 1：12 （V/W） for 7 hours at 25℃. The extraction was then repeated for 3 times. Under the above-mentioned conditions, yield of liposoluble pigment was 1.8%.
