摘要
本文采用正交试验的方法研究了酸解法从豆腐柴叶中提取果胶的最佳提取工艺条件 :萃取温度 90～ 95℃、溶液pH值 1 5、萃取时间 5 0～ 6 0min、料液比 1∶2 0 ,在此条件下豆腐柴叶果胶的提取率为14 %～ 17%。
The process conditions of extracting pectin from premna microphylla with acid solution by means of orthogonal design were studied in this paper.It is concluded that the optimum conditions are extraction temperature is 90～95℃,pH is 1 5,extraction time is 50～60 min,the rate of solid to solution is 1∶20.In such conditions the ratio of pectin gained is 14%～17%.
