| 摘 要： | 抗坏血酸与瓜尔豆胶按照一定的比例混合后,与适量的玉米淀粉配制成淀粉水溶液。充分糊化后,放置不同时间,测定并分析淀粉溶液在回生过程中溶液透光率、脱水率、结晶度及焓变等相关参数的变化情况。研究结果表明,抗坏血酸和瓜尔豆胶按不同比例混合,对淀粉的回生具有不同程度的抑制作用。在相同条件下,二者配比为2∶1时抑制效果最好。

| Abstract: | Ascorbic acid and guar gum are mixed according to certain proportion,mixed the right amount of corn starch into starch solution.After fully gelatinization and placing different time,solution light transmittance,dehydration rate,crystallinity and enthalpy variation of starch solution in retrogradation are analyzed.The results show that ascorbic acid and guar gum mixed according to different proportions restrain the retrogradation of starch with different degree.Under the same conditions,the inhibitory effect... |
