摘要: 本研究利用动态超高压技术研制纳米级膳食纤维,并对纳米级膳食纤维的比表面积、持水力和膨胀率等性质进行研究。结果表明:制备纳米级豆渣膳食纤维的最佳压力为90MPa,纳米级豆渣膳食纤维比表面积达到1.8189m2/g,约是普通纤维的2倍,纳米级豆渣膳食纤维持水力和膨胀率分别达到15.3265g/g和21.5017g/g,均约是普通纤维的3倍。

Abstract: The research on preparation of nano dietary fiber by Microfluidizer homogenizer, and characteristics of T nano dietary fiber, such as surface areas, expansion ratio, water-retaining capability. The results show that the optimal homogenization pressure is 90MPa; surface area is 1.8189m2/g, and it is twice higher than normal fiber; and expansion ratio is 15.3265g/g, water-retaining capability is 21.5017g/g, both of them were three times higher than normal fiber.

Key words: nano dietary fiber, granularity, surface area, expansion ratio, water-retaining capability
