摘要/Abstract

摘要：以橘皮为原料，稀盐酸为溶剂，超声萃取、乙醇沉淀法提取果胶.探讨了温度、液料比、pH值和超声提取时间等因素对果胶提取率的影响.通过正交实验确定的最佳工艺条件是：pH值为2.0，温度70 ℃，超声提取时间30 min，浸提液料比为40 mL/g.果胶提取率最高达到13.9%.

关键词： 橘皮, 果胶, 浸提, 超声辅助溶剂法, 正交试验

Abstract: Extracting pectin from orange peel with ultrasonic-assistant solvent method was studied,hydrochloric as solvent and ethanol as precipitator.The influencing factors including temperature,liquid-to-solid ratio,pH value of the solution and extracting duration are studied.The optimal process conditions were obtained by orthogonal analysis as follows:pH value 2.0,temperature 70 ℃,extracting duration 30min,the liquid-to-solid ratio was 40 mL/g，and at the condition the extracting rate of pectin was 13.9%.

Key words: orange peel, pectin, extraction, ultrasonic-assistant solvent method, orthogonal experiments
