【摘要】 以带皮豆渣为原料,分别通过正交实验、Box-Behnken实验方法对改性大豆纤维粉制备工艺中的脱腥、酶法改性工序进行参数优化,确定的脱腥工艺参数为:液料比1∶1,反应温度60℃,反应时间40min,pH5·0;采用纤维素酶进行酶法改性工艺参数为:酶浓度1·57%,酶解时间3·02h,酶解温度50·35℃,酶解pH5·13。更多还原

【Abstract】 With skin soybean dregs as raw material,the deodorization and enzymatic modification process parameters were optimized through orthogonal test and Box-Behnken experimental design for preparation of modified soybean dietary fiber powder,respectively. The deodorization process parameters were:liquid material ratio of 1∶1,reaction temperature 60℃,reaction time 40min,pH5.0. The enzymatic modification process parameters were:enzyme concentration of 1.57%,hydrolysis time 3.02h,hydrolysis temperature 50.35℃ and enzyme pH5. 13.更多还原
