中草药提取液及酶制剂在烟叶中的应用

Application of Chinese Herbal Extracts and Enzyme Agents to Tobacco Leaf

为改善烟叶的燃吸品质,考察了槐米、金针花等20余种中草药浸膏,以及纤维素酶、木瓜蛋白酶和中性蛋白酶3种酶制剂对B3F烟叶的处理效果。结果表明:①槐米浸膏、金针花浸膏和中性蛋白酶处理的烟样香气质提高,香气量增加,余味改善;②槐米浸膏0.03%、金针花浸膏0.01%、纤维素酶0.1%和中性蛋白酶0.2%的混合物处理的B3F烟叶样品于自然条件下放置1个月,其总糖、总氮和烟碱的含量分别与未处理的对照样品自然醇化1年、3个月和9个月的相当。

In order to improve the smoking quality of tobacco leaf, the effects of concretes of more than 20 kinds of Chinese herb, such as Flos Sophorae immaturus, day-lily, etc. , and 3 enzyme agents, including cellulase, papain, and neutral proteinase, on the chemical compositions and smoking quality of flue-cured tobacco leaf, B3F, were studied. The results showed that： 1 ） the flavor quality, flavor concentration and taste of B3F were obviously improved by the addition of Flos Sophorae immaturus concrete, day-lily concrete or neutral proteinase; and 2）the contents of total sugar, total nitrogen, and nicotine in B3F treated with the mixture of 0.03% Flos Sophorae immaturus concrete, 0.01% day-lily concrete, 0.1% cellulase and 0.2% neutral proteinase and stored at room temperature for one month were close to their contents in untreated B3F aged for one year, three months and nine months, respectively.
