应用复合酶工艺技术提高烟梗浸膏品质的研究

为了改善烟梗浸膏的品质,在造纸法再造烟叶生产中应用了复合酶工艺技术。结果表明:淀粉酶、果胶酶和木聚糖酶的最适用量分别为0.5%、0.5%和1.0%;复合酶的最佳使用条件为:pH 4.91、温度55℃;洗梗液在生产中可实现恒pH值、恒温控制和过滤;经复合酶处理的烟梗、梗膏和再造烟叶的水溶性糖含量有较大的变化;复合酶洗梗技术可明显提高再造烟叶的内在品质。

Study on Applying Complex Enzyme Technology to Improve Quality of Tobacco Stem Concentrated Solution

In order to improve the quality of tobacco stem concentrated solution,the complex enzyme technology was applied to the reconstituted tobacco leaves produced by paper-making process.The results showed that the optimum dosages of amylase,pectinase and xylanase were 0.5%,0.5% and 1.0%,respectively.The optimum conditions for the application of complex enzymes were pH 4.91 and temperature 55 ℃.The pH-value and temperature of stem-washing solution could be constantly controlled,and the stem-washing solution could be filtrated.The water soluble sugar content in the tobacco stem,stem cream and reconstituted tobacco leaf changed greatly after the application of complex enzymes.The stem-washing technology by using complex enzymes could obviously improve the inherent quality of the reconstituted tobacco leaves.
