Description

一种鲜烟叶生产酒精的方法
技术领域
 本发明属于化工领域，涉及一种鲜烟叶生产酒精的方法。
背景技术
烟草是我国农业经济的主导产业之一。据统计，全国烟草种植面积达1500多万亩，除去可用于深加工的正常烟叶外，还剩有烟秆、烟梗、烟花、烟杈、底脚叶和部分顶叶等数量巨大的烟草废弃物，其中废弃鲜烟叶每年约有180万吨。废弃鲜烟叶含有碳水化合物4-5%、还原糖2.5-3%，纤维素1.5-2%，还有少量的蛋白质、烟碱及挥发酸、矿物质等，废弃了十分可惜，不但浪费了资源，有时还会造成环境污染。
发明内容
本发明提供了一种鲜烟叶生产酒精的方法。
本发明的目的是按下述方式实现的：鲜烟叶，破碎，打浆，加入干烟叶粉20%、果胶酶0.15%、纤维素酶0.1%，混合均匀，50℃，酶解90min，加入盐酸2%，140-145℃水解60min，冷却至80℃，离心，得上清液；加入硫酸铵0.1%、磷酸二氢钾0.1%、硫酸镁0.05%，调pH值至5.0-5.5，85℃杀菌5min，冷却至30℃，接种酒精活性干酵母0.1%、果胶酶0.1%、纤维素酶0.05%，28-32℃发酵60h，在发酵至24h、40h时分别添加干烟叶粉10%、8%，发酵结束后进行蒸馏，即得酒精。
所述的干烟叶粉是指鲜烟叶经烘干、粉碎、过40目筛制得的干烟叶粉。
经过检测，鲜烟叶成分如下：水分85%、水溶性总糖4.48%、还原糖3.98%、纤维素1.87%、蛋白质0.08%、总氮0.03%；干烟叶粉成分如下：水溶性总糖29.85%、还原糖26.50%、纤维素12.46%、蛋白质0.92%、总氮0.37%。由成分分析可以见，鲜烟叶中含有可发酵糖、蛋白质和氨基酸，但总糖含量偏低。为了提高生产效率和酒精收率，并充分利用烟叶资源，本发明将鲜烟叶经烘干、粉碎制成干烟叶粉，其水溶性总糖接近30%，再加回到配料中，解决了初始总糖偏低的问题；同时为了有效利用烟叶含有的纤维素，采用酶水解加酸水解的双重水解方式，来提高利用率。本发明为大量废弃烟叶的综合利用提供了一条有效途径。
四、具体实施例
实施例1
具体实施方式：称取鲜烟叶1000g，破碎，打浆，加入干烟叶粉200g、果胶酶1.5g、纤维素酶1g，混合均匀，50℃，酶解90min，加入盐酸20mL，140-145℃水解60min，冷却至80℃，离心，得上清液；量取上清液500mL，加入硫酸铵0.5g、磷酸二氢钾0.5g、硫酸镁0.25g，调pH值至5.0-5.5，85℃杀菌5min，冷却至30℃，接种酒精活性干酵母0.5g、果胶酶0.5g、纤维素酶0.25g，28-32℃发酵48h，发酵24h时添加干烟叶粉50g，发酵至40h时再添加干烟叶粉40g，发酵结束后进行蒸馏，即得酒精。
