摘要/Abstract

摘要： 为提高大豆皮中水不溶性膳食纤维的利用率，本研究采用气流粉碎得到不同粒度的超微型大豆皮水不溶性膳食纤维，分别测定了超微型大豆皮水不溶性膳食纤维的体积平均粒径、比表面积、持水力、持油力、黏度曲线、阳离子交换能力等理化性质，同时分析了处理后的水不溶性膳食纤维对油脂、胆固醇、胆酸盐、葡萄糖和重金属的吸附能力。结果表明：体积平均粒径为16.24 μm的大豆皮水不溶性膳食纤维其持水力、持油力分别达到2.31、 5.27 g/g，比61.21 μm的提高了1.07、2.53 g/g；黏度和阳离子交换能力也有了显著性改变；超微粉碎改性大豆皮水不溶性膳食纤维对油脂、胆固醇、胆酸盐、葡萄糖和重金属的吸附能力有明显增强，在体积平均粒径为28.27 μm和 40.17 μm时吸附能力较高。超微粉碎对大豆皮水不溶性膳食纤维的理化和吸附特性均有明显改良作用，这为大豆皮的深加工提供了理论参考。

Abstract: The effect of ultrafine comminution on physicochemical and adsorption properties of insoluble dietary fiber (IDF) from soybean hull was studied. The physicochemical properties included particle size, specific surface area, water-holding capacity, oil-holding capacity, viscosity curve, and cation-exchanging capacity. The in vitro adsorption capacity for fats, cholesterol, bile salts, glucose and heavy metals of IDF samples were determined. The results showed that the water-holding capacity and oil-holding capacity of IDF powder with a particle size of 16.24 μm were 2.31 and 5.27 g/g, respectively, which were 1.07 and 2.53 g/g higher than those of the sample with a particle size of 61.21 μm, respectively. The viscosity value and cation exchange capacity also showed significant changes. The adsorption capacity for fat, cholesterol, bile salt, glucose and heavy metals of ultrafine IDF were significantly increased especially for samples with a particle size of 28.27 and 40.17 μm. Conclusively, ultrafine comminution could significantly improve physicochemical and adsorption properties of insoluble dietary fiber from soybean hull, which would provide a theoretical reference for intensive processing of soybean hull.
