| 摘 要： | 以3种不同筋力小麦粉为原料,研究了抗性淀粉(Resistant Starch,RS)对小麦粉凝胶质构特性的影响。结果表明:抗性淀粉不能形成凝胶,添加5%～20%抗性淀粉的小麦粉配粉可形成凝胶。抗性淀粉RS3和RS2对强筋、中筋和弱筋小麦粉凝胶的影响趋势相同,随着配粉中抗性淀粉的比例逐渐增加,各凝胶的硬度、黏着性和胶着性显著降低,中筋粉的硬度、黏着性和胶着性值最高,弱筋粉次之,强筋粉最低;3种筋力小麦粉及其抗性淀粉配粉的弹性和凝聚性差异很小。

| Abstract: | In this research,the effect of resistant starch on gel textural properties of wheat flour was investigated.The results show that all the wheat flour and RS-wheat flour mixtures with 5% ～20% RS were able to form gels except resistant starch.The influential tendencies of RS3 on control wheat gels and RS-wheat mixed gels were consistent with RS2.The hardness,adhesiveness and gumminess for RS-wheat mixed gels decreased as the RS proportion in the gel increasing,and the values for RS-intermediate gluten wheat flour mixed gels were the highest,followed by RS-weak gluten wheat flour gels and then RS-strong gluten wheat flour gels.The springiness and cohesiveness for control wheat flour gels and RS-wheat flour mixed gels were observed to be almost the same. |
