摘要: 本实验探索了超高压处理对小麦膳食纤维性质的影响。分别考察了处理前后样品的持水率、膨胀率、黏度和纤维结构的变化。结果表明:处理后样品的持水率和膨胀率都有较大的提高;黏度没有明显变化;处理后样品的组织结构更加疏松,空隙增多增大,但是其片层状空间结构没有改变。本实验为小麦膳食纤维的改性研究奠定了基础。

Abstract: The influences of ultra high pressure treatment on wheat insoluble dietary fiber’s characteristics were studied.The change of sample’s water retention capacity(WRC),swelling capacity(WSC),viscosity and structure was inspected respectively.The result showed that the treated sample’s WRC,WSC and viscosity increased and it’s texture became loose and porous without space structure change.The research laied base for wheat dietary fiber modification study.
