【摘要】 以干橙皮为原料，研究了离子交换树脂法提取果胶的多种影响因素、工艺条件以及除杂问题．结果表明，以离子交换树脂法提取橙皮果胶的最佳条件为：水料比为 ３０∶１， ０．０１×７阳离子交换树脂的用量为５％，在７５℃、ｐＨ为２．０下处理９０ｍｉｎ，其果胶得率高，果胶质量优于酸法提取所得果胶，产品质量指标达到或优于国家标准．更多还原

【Abstract】 The ion exchange resin (IER)has been used to investigate the influencing multifactors,pectin extraction technique from orange peel and pectin purification in this paper. As a result the optimal extrac tion condition is that the ratio of raw material to the added water keeps 30∶1 with 0.05 part IER(0.01 ×7)at 75℃,pH 2.0 for 90 minutes. The recovery ratio of pectin and its quality with IER treatment are superior to those with the acid extraction method. The quality indexes of the product reach or surpass those formulated in China’s nation standard.更多还原
