| 摘 要： | 以马铃薯渣为原料,研究粉碎粒度对生物酶法处理产物的持水力、持油力、溶胀性的影响,以及生物酶处理后粉碎与生物酶处理前粉碎,对产物以上性质的影响.结果表明,随粒度的减小,以上性质都呈下降趋势;生物酶处理后粉碎与生物酶处理前粉碎相比,以上性质有所上升.确定了用200 μm～150 μm(80～100目)原料进行马铃薯渣生物酶法提取膳食纤维实验,制备的产品粉碎为200μm(80目)是最合适的工艺条件.

| Abstract: | Using potato pulp as raw materials, the effects of particle sizes of dietary fibre crushed before or after enzymatic treatment on water-holding capacity (WHC), oil-binding capacity(OBC), and swelling capacity(SC) were studied. Results showed that the WHC, OBC and SC of the product were reduced by enzymatic treatment, but these properties of the dietary fibre crushed after enzymatic were higher than those of the enzymatic treated crushed product. For extraction of dietary fibre from potato pulp, the best par... |
