摘要:  采用化学法合成淀粉魏酸酯,观察它的理化和营养特性。结果表明,淀粉阿魏酸酯比原淀粉具有更低的粘度和更强的吸水性,在低温下产生凝沉淀粉量很少。它不易被淀粉酶水解,在结肠微生物作用下,阿魏酸的释放率和释放速度大大高于麦膳食纤难,发酵至16h时释放率达94.5%,24h达98.2%。淀粉阿魏酸酯发酵液对亚硝酸盐具有较强而快速的清除作用。采用淀粉阿魏酸酯培养乳酸菌发现,它能促进保加利亚乳杆菌和嗜热链球菌的繁殖,并使之在贮藏过程中维持较高活力。

Abstract: Ferulic acid starch esterified starch(starch ferulate)was synthesized and its funcfional and biological properties were determined.Starch ferulate showed lower viscosity,higher water-holding capacity,and much less retrogradation during low temperature storage than its native one.It was only partly hydrolyzed(lower than 10%)by diastase and the bound ferulic acid was largely released by colon micro biota.The rate and extent of released ferulic acid were higher than dietary fibres from wheat bran.Also,it prologed the activity two yogurt strains during storage.
