摘要: 本文采用酸提取方法对大豆种皮果胶的提取工艺条件进行研究,考察了温度、pH、料液比、提取时间等因素对果胶收率的影响。确定了酸提取大豆种皮果胶的最佳工艺条件:pH1.5、提取温度为85℃、提取时间30min、料液比为1:8。

关键词: 大豆种皮, 果胶, 酸提取工艺

Abstract: Acid-extraction of pectin from soybean hull was studied. The effects of temperature, pH, ratios of soybean hull to extraction solvent, extraction time on the yields of soybean hull pectin prepared were measured. The results showed that the optimum conditions were: extraction temperature 85℃, pH1.5 and ratios of soybean hull to extraction solvent 1:8, extraction time 30min.

Key words: soy hull, pectin, acid-extraction
