摘要: 本实验以沂州木瓜为原料,采用盐酸浸提、乙醇沉淀法进行果胶提取的工艺试验研究。单因素试验的研究结果表明,提取液pH值为2.0左右,提取液温度为80~90℃,提取的液料质量比在4左右,提取时间在1~1.5h时,果胶提取效果较好;在单因素试验的基础上,通过正交试验,优化果胶提取的工艺参数,得出了从沂州木瓜中提取果胶的最佳工艺条件为:提取液pH2.0,提取液温度90℃,液料质量比4,提取时间1h。

Abstract: The experiments of pectin extraction from Yizhou Chaenomeles sinensis were carried out by the hydrochloric acid extraction method and the ethanol deposition method.Results showed that the extraction rate of pectin is higher when the pH of extraction solution was around 2.0,the extraction temperature was 80 to 90℃,the ratio of extraction solution to material was around 4,and the extraction time was 1 to 1.5 h.On the base of single factor test,the orthogonal test was used for optimization of technological parameters.The optimal technological conditions are pH value 2.0,temperature 90 ℃,extraction solution-material ratio 4,and time 1 h.
