探讨了以红江橙皮渣为原料用盐析法提取果胶的工艺条件，讨论了各种因素对果胶质量和提取率的影响，找到了较佳的提取工艺条件，为批量生产提供了依据。
对用红江橙皮渣提取果胶的最佳工艺条件进行了研究，所得最佳工艺条件为：选取Al2(SO4)3作为果胶沉淀剂，酸提取条件为水料比20:1，pH值为2.0，温度85℃，时间120min；盐析条件为加盐量5mL，pH值为7.0，时间60min，温度75℃；脱盐步骤中以脱盐液组合为3%HCl、50%乙醇、47%水，脱盐液用量为150mL，脱盐时间30min,果胶得率为6.70%。

关键词：果胶；皮渣；盐析法；酸水解法；提取

This paper explores the Red River to hesperidin salt slag as raw material extraction of pectin analysis, the conditions, discussion of various factors on the quality of pectin extracted and the impact of the rate found better conditions for the extraction process, To provide a basis for mass production. Jiang's right to use the orange peel extract pectin slag the optimum conditions for the study, obtained optimum conditions : To Al2 (SO4) 3 as the precipitating agent pectin, acid extraction ratio of water to 20 : 1. pH 2.0, temperature 85 ° C, 120 min time; Analysis of salt and salt conditions volume 5 mL, pH 7.0, for 60 min, temperature 75 ° C; Desalination steps to desalination liquid composition of the 3% HCl, 50% ethanol, 47% water, Desalination liquid dosage of 150 mL, desalination time 30 min, pectin yield of 6.70%.

Keywords : pectin; PEEL; Analysis of salt; Acid Hydrolysis; Extraction
