【摘要】 对荸荠果皮不溶性膳食纤维的化学法提取工艺进行了研究。通过对氢氧化钠浓度、处理时间、处理温度与原料颗粒大小等影响因素进行单因素及正交实验,获得最佳工艺条件为氢氧化钠浓度4%、处理温度40℃、处理时间1h、原料过40目筛。在此条件下不溶性膳食纤维的提取率为85.5%,产品纯度为30.2%。更多还原

【Abstract】 Study on the extraction of insoluble dietary fiber from Chinese water chestnut pericarp by chemical method. The optimum processing conditions were made through the single factor and orthogonal experiments: adopt 4% NaOH solution to handle 1h at 40℃, the granularity of material is lower than 40-eyes-sieve. At this condition, the extraction efficiency of insoluble dietary fiber is 85.5%, the product with purity 30.2%.更多还原
