摘要: 对大麦β-淀粉酶水解蜡质玉米淀粉制备的β-限制糊精的颗粒形态、结晶性及特性进行研究。结果表明:β-限制糊精颗粒有棱角、呈不规则状,非结晶结构,β-限制糊精糊凝沉性弱,溶解度与膨润力、透明度和冻融稳定性均较原蜡质玉米淀粉有明显的改善,吸湿性比蜡质玉米淀粉略小。β-限制糊精具备的这些优良的性质和良好的加工性能,使其在食品加工业中有广阔的应用前景和很大的开发潜力。

Abstract: The particle morphology, crystallinity and some properties of β-limit dextrin prepared by enzymatic hydrolysis of waxy cornstarch with β-amylase were studied. The results showed that the particles of β-limit dextrin were angular, irregular and non-crystal. The dextrin revealed low retrogradation and more remarkable improvement on solubility, swelling power, transparency and freeze-thaw stability when compared with raw waxy cornstarch. Its hygroscopicity was a little lower than that of raw waxy cornstarch. Due to its unique properties and excellent processing performance, the application prospect ofβ-limit dextrin in the food processing industry is promising.

Key words: β-limit dextrin, morphology, crystallinity, properties
