摘要:

探讨亲水胶体的种类和添加量对面包品质、面粉糊化特性和面团流变学特性的影响。结果表明:添加亲水 胶体能改善面团的抗拉伸强度,增强面团弹性,但降低了面团的延伸性。添加适量的亲水胶体能有效改善面包的焙 烤品质,增大面包的比容、面包心的弹性,降低面包心的硬度。黄原胶、羧甲基纤维素钠(CMC)、魔芋胶、瓜尔豆 胶、谷朊粉的添加量分别为0.1%、0.5%、0.3%、0.15%、0.5%时,面包的焙烤品质最好。

Abstract:

The effect of hydrocolloid type and amount on bread quality, pasting properties of flour, and rheological
properties of dough were investigated. The results showed that tensile strength and elasticity of dough were improved by
addition of hydrocolloids, while dough extension was decreased. By addition of proper amount of hydrocolloids, bread
quality was improved effectively, showing higher specific volume and elasticity and lower hardness of bread core. The
best bread quality was obtained by addition of 0.1% xanthan gum, 0.5% CMC, 0.3% konjac gum, 0.15% guar gum and
0.5% gluten.

Key words: hydrocolloids, bread, pasting property, rheological property
