摘要
采用酒精沉淀法从柚皮中分离果胶,以促进柚子的综合利用开发。得出在酸水解提取果胶的工艺中提取液酸度是影响果胶收率的主要因素,并取得了果胶提取的最优提取条件为酸度为pH=2,提取温度为95℃,提取时间为70min,液固比为201∶,在该条件下果胶收率最高。
The alcohol precipitating method is adopted to separate pectin from pomelo peel to promote the pomelo's comprehensive utilization and development. The major affecting pectin yield is the extaet acidity. The optimum parameters of extraction are gained as follows: acidity pH = 2, temperature 95℃, time 70min, the ratio of liquid to solid 20:1.
