摘要:

提出了一种不使用酒精的果胶生产工艺——离子交换法制备果胶。以苹果渣为原料,以酸提液中果胶收率为指标,通过单因素和正交试验确定了最佳提取工艺参数。以透光率和收率为指标,完成了离子交换除杂工艺中树脂的选型以及工艺参数条件的优化选择。实验表明,阴离子树脂D290 和阳离子树脂D061 为最佳选择,上柱过程的最佳流速为1BV/h,新工艺不仅克服了传统工艺大量使用乙醇的弊端,而且产品的主要性能指标均优于传统工艺。

Abstract:

A new preparation technology of pectin from apple pomace without ethanol-ion exchange method was proposed in this study. The optimized extracting conditions were determined by single-factor and orthogonal test with pectin yield as value index, while the optimized processing parameters and the choice of resin in removing impurities by ion exchange were discussed with transmittance and pectin yield as value indexes. The results showed that anion resin-D290 and cation resin-D061 are the best choice and the optimal rate is 1 BV/h for the column process. This new method overcomes the disadvantage of the traditional preparation technology by using mass ethanol with the better main indexes of products.

Key words: ion exchange method, pectin, apple pomace
