摘要:本研究对板栗乙醇发酵的几种主要影响因素进行了研究,并对发酵工艺进行了探讨。实验结果可知,板栗乙醇发酵的较优工艺为:板栗粉碎颗粒大小为60目,料水比为1:3.5,液化酶(耐高温α-淀粉酶)添加量为20U/g原料,液化温度90℃,液化时间60min;糖化酶添加量为120U/g,糖化温度60℃,糖化时间30min,糖化PH为5.0;使用酵母为耐高温酿酒高活性干酵母,接种量为0.02%,发酵温度30℃,发酵时间72h。板栗含有40%~60%的淀粉,用板栗淀粉发酵生产乙醇,不仅开拓了板栗的应用范围,提高了其经济价值,促进山区的经济发展,也为乙醇生产提供了很好的原料资源,为生物质能源利用提供新的途径与方法。
Factors influencing the experimental technology the ethanol fermentation by and conditions. The results using chestnut starch were showed that the optimum in vestigated to probe conditions of ethanol fermentation by using chestnut starch were as follow: the granule 60 meshes the ratio of chestnut starch to water 1 : 3.5 α-amylase 20 U/g time and temperature of liquefaction:60 min , 90℃, saccharificafion temperature and time: 60℃, 30 min, glucoumylase 120 U/g, before saccarificafion, using sulfuric acid to regu- late pH5. 0, fermentation temperature 30℃ the quantity of the temperature tolerant active dry yeast 0.02%, and the time of fermentation 72 h. The contents of starch in chestnut fruit ranged from 40% to 60 %. The technique not only enlarges chestnut's application, improves its economic value, but also offers the enough materials to produce ethanol, and provides a new approach to the utilization of biomaterial resource.
