从苹果渣中提取果胶的工艺研究

Study on extraction process of pectin from apple pomace

以苹果渣为原料,探讨了盐析法提取果胶的最佳工艺条件。结果表明,水解部分:料液比为1∶13(g/mL),不同酸对提取率影响不大,可选用常用酸(如盐酸、硫酸)作水解剂;盐析部分:pH值为2.0,盐析温度为85℃,盐析时间为2 h。

By using dried pomace as the raw material, probed the optimal extraction process：The result shows that ：①Hydrolysis, solid-liquid ratio 1 ： 13 （g/mL） ,different ratio of acid in extraction system had no effect on extraction yield; ②Salt precipitation, pH 2.0, temperature 85 ℃, salt precipitation time 2.0h.
