低温挤压加酶脱胚玉米粉生产酒精试验（Experiment on Productive of Ethanol for Extruded Corn Grist Degermed with Enzyme Preparation at Low Temperature）
脱胚玉米粉 挤压 低温
2009/11/24
研究低温挤压加酶脱胚玉米粉，直接液化、糖化、发酵、蒸馏生产酒精技术，并考察了脱胚玉米粉挤压前耐高温α淀粉酶添加量、挤出物糖化时糖化酶添加量、糖化时间、液化时耐高温α淀粉酶添加量、发酵时酵母添加量对醪液的主要考察指标（醪液的酒精度、淀粉出酒率、残总糖）的影响规律。结果表明，本研究的挤压-糖化-发酵系统主要参数优化值对应的醪液发酵48h的酒精度、淀粉出酒率分别为13.45%和59.21%，高于对照挤压...
