| 摘 要： | 以玉米皮为原料,分别制备A(玉米皮水不溶性膳食纤维)和B(混合玉米皮膳食纤维)。通过对比A和B的持水力、膨胀力、吸油力以及对胆固醇、亚硝酸根离子的吸附能力这些指标来研究玉米皮膳食纤维的性质。试验结果表明:B的性能优于A。B的持水力和吸油力比A分别高出20.21%和9.87%;A的膨胀力比B高出4.14%;随着pH值的不断增大,膳食纤维对胆固醇的吸附能力增强,在pH7时B对胆固醇的吸附能力比A提高了约33.33%;溶液中残余亚硝酸根离子的浓度随着时间延长而呈下降趋势,并且pH值对样品吸附亚硝酸根离子的能力有较大的影响,在60 min时A和B在pH2时吸附亚硝酸根离子的浓度均比在pH7时高出46.72μmol/L。

| Abstract: | Using corn bran as raw material,A(corn bran insoluble dietary fiber) and B(hybrid corn bran dietary fiber) were prepared respectively.By comparing the indicators of water holding capacity,swelling capacity,oil absorption ability as well as cholesterol,nitrite ion adsorption capacity of A and B,the properties of corn bran dietary fiber were studied.The results showed that: the properties of B were superior to A.The water holding capacity and oil absorption ability of B were both higher than these of A by 20.... |
