摘要
通过在烟草水提液中加入乙醇,选择性地去除烟草水提液中对再造烟叶感官品质产生不利影响的物质,提高烟草水提液中有效成分相对含量,实现从烟草水提液制备烟草浸膏。考查了乙醇终体积分数和烟草水提液初始密度这2个重要因素对烟草水提液醇沉效果的影响。结果表明,①烟草水提液醇沉过程中大分子物质(蛋白质、果胶和淀粉)去除率达到90%以上,烟碱和总糖保留率为70%以上,中性致香成分保留率达90%以上;②制备的浸膏中中性致香含量相对于烟草水提液为4~6倍。研究可为造纸法再造烟叶生产过程中过剩烟草水提液制备烟草浸膏提供参考依据。
In order to improve the relative content of effective components in tobacco water extract,ethanol was added into tobacco water extract to selectively remove the substances that had adverse effects on the sensory quality of reconstituted tobacco,and then tobacco extrat was prepared.In this study,the final concentration of ethanol and the initial density of tobacco water extract were investigated.The results showed that:①the removal rate of macromolecular substances(protein,pectin and starch)was more than 90%,the retention rate of nicotine and total sugar was more than 70%,and the retention rate of neutral aroma components was more than 90%.②The neutral aroma content of the extract was 4~6 times as much as that of the tobacco water extract.In conclusion,the research above provided a reference for the preparation of tobacco extract from excess tobacco water extract in the production of paper-making process reconstituted tobacco.
