摘要
豆渣中含有丰富的纤维素,从中可以提取出水溶性大豆多糖,该多糖特性优良。对该多糖进一步改性修饰之后,将其与淀粉作用,通过DSC实验发现:水溶性大豆多糖能显著降低老化淀粉的吸热焓,有效延缓淀粉的老化作用。水溶性大豆多糖的这种延缓淀粉老化的作用,可以延长食品货架期,对食品加工业有着重要意义。
Soluble soybean polysaccharides （SSPS） were extracted from bean curd waste, because there were abundant nutritional components in bean curd waste. SSPS were modified by chemical. The resultant material was confirmed by DSC. When they interacted with starch, they could decrease decalescence enthalpy of starch, and slow aging process of starch. This property of modified SSPS （SSPS-G） could prolong shelf life of food, and be applied to food manufacturing industry.
