摘要: 本实验采用酸解铁盐沉析法,从三叶木通果皮中提取到了质量较高的果胶。结果表明,酸解法提取果胶的最佳工艺参数为:温度95~100℃,pH1.0,时间2.0h,固液比1:25~1:30。在此条件下测得果胶的提取率为11.08%;活性炭脱色工艺为:温度65℃,35min,0.7~0.9g活性炭/100ml浸提液;沉析工艺为:在每100ml果胶溶液中,加入20%FeCl35ml,pH为4.0左右,沉析时间3h以上;脱盐工艺为:每2g果胶盐置于150ml脱盐液(65%乙醇+4%盐酸+31%水(V/V))中,时间25min左右。

Abstract: Extraction technology of pectin from Akebia trifoliate koiaz peels was studied by acid in this study. The optimal extracting technics were: 95~100 ℃, pH1.0, 2.0 h and the ratio of peel materials to water 1:25~1:30. With this way, the extraction rate of extracted and unrefined pectin was up to 11.08%. The decoloring technics were: 0.7~0.9 g active carbons mixed into 100 ml pectin extracting solutions for 35 min about 65 ℃; The optimal precipitant technics were: 5 ml 20% FeCl3 (pH 4.0, adjusted with ammonia water) added into 100 ml pectin extracting solution, and precipitated over 3 h. And the desalting technics were: 2 g pectins put into 150 ml desalting solutions (65% ethanol + 4% hydrochloric + 31% distilled water). After 25 min, pectins were carefully washed with 100% ethanol.
