用超声波、盐析法提取仙人掌果胶的研究

主要研究了用超声波辅助盐析法从仙人掌中提取果胶,通过正交实验,对其工艺条件进行探讨,得出最佳的条件及产率。对于间接超声波作用,其最佳提取条件是提取功率40%,提取时间15min,提取温度75,提取液为15mL,即1倍的提取液;对于直接超声波作用,其最佳提取条件是提取功率60,提取时间15min,间歇比60%,提取液37.5mL,即2.5倍的提取液,此时果胶沉析的最佳条件是PH值为4.5,温度60,铝盐量9mL,得出的果胶产率是9.15%。

Study of the Extracting Pectin from Cactus by Ultrasonic Wave and Salt

This paper mainly study the method of extracting pectin from cactus by ultrasonic wave supporting the salting-out way. After orthogonal design and many times of approaches its technical conditions, we conclude the best environments for extracting and the rate of production. For the indirect ultrasonic wave function, its best extracting environments are the power 40%,the time 15 min, the temperature 75  , the liquid 15 ml. , namely 1 withdrawing of times liquid; For the direct ultrasonic wave function, its best extracting environments are the power 60, withdrawing time 15 min, intermittent ratio 60%, withdrawing the liquid 37.5 ml., namely 2.5 withdrawing of times liquid; And in the conditions, the best withdrawing environments of pectin are pH 4.5 ,temperature 60 , aluminum salt measure 9 ml. .The rate of production is 9.15%.
