【摘要】 用水提取的仙人掌多糖常含有蛋白质,实验以多糖损失率和脱蛋白率为衡量指标,选用了3种方法:Sevag法、三氯乙酸法和酶法对仙人掌多糖提取物进行脱蛋白处理。实验结果表明:酶法、三氯乙酸法和Sevag法的脱蛋白率分别为89.6%、56.2%和45.5%,多糖损失率分别为7.2%、9.5%和13.6%。经比较认为:酶提取法是替代常规方法的一种有效方法。更多还原

【Abstract】 In order to obtain the purified polysaccharide from cactus,the effects of three methods for removing protein from the extracted polysaccharide from cactus was studied by comparing the percentage of the decomposed polysaccharide (PDP) and the removed protein (PRP). The results showed that the PRP for the method of using enzyme、using CCl3COOH and using Sevag were listed as follows: 89.6%、56.2% and 45.5%,whilie the PDP for three methods were 7.2%、9.5% and 13.6%,respectively. Compared with normal method,the application of enzymatic removal of protein was an effective and alternative method.更多还原
