【摘要】 首先研究了吸油率作为考察淀粉成孔指标的可行性;研究酶解工艺时,在单因素实验基础上再进行正交实验,得到最佳酶解工艺条件为:温度55℃,时间28h,pH5.6,淀粉浆浓度60％,加酶量50％,并进一步把此条件运用到放大实验中,取得了较好结果。更多还原

【Abstract】 The oil adsorption rate was used as the index to evaluate the porous starch, and the optimal conditions for porous starch production were obtained by single factor and orthogonal experiment: the reaction temperature was 55℃, the reaction time was 28h, the pH was 5.6, the solid concentration was 60%(w/v), the amount of complex enzymes was 50% of what can hydrolyze raw starch theoretically. A good result was also obtained in scale up experiment.更多还原
