利用复合酶制剂改善烟叶枯焦气的研究

Study on Using the Compound Enzyme Preparation for Improving the Tobacco Burnt Gas

为降低烟叶枯焦气,增加烟香,改善余味,通过单酶特性梯度试验和正交试验,利用复合酶制剂能有效改善烟叶枯焦气。结果表明,在试验范围内:(1)对复烤山东TBO片烟(2009)改善效果为,蛋白酶>酸性木聚糖酶、纤维素酶>淀粉-1,4-葡萄糖苷酶、脂氧合酶;(2)按在线添加量0.4%计算,改善烟叶枯焦气的复合酶制剂配比比例为,蛋白酶(30%),淀粉-1,4-葡萄糖苷酶(20%),酸性木聚糖酶(20%),脂氧合酶(2%),纤维素酶(5%),纯净水(23%)。由此可见,复合酶制剂可以针对性解决烟叶的质量缺陷,提高烟叶的感官质量。

In order to reduce the tobacco burnt gas, increase smoke flavor and improve taste, By means of study on characteristics of single enzyme gradient test and orthogonal experiment, the redrying Shandong tobacco（2009） burnt gas could be improved by using compound enzyme preparation. The results showed that, in the experimental range：（1）the effect of compound enzyme preparation on the improvement of burnt gas were proteaseacidic xylanase, cellulosestarch-1, 4-glucosidase,lipoxygenase;（2）According to calculation of online 0.4% additive amount, the formulation of compound enzyme were protease（30%）, starch-1, 4-glucosidase（20%）, acidic xylanase（20%）, lipoxygenase（2%）, cellulose（5%） and water（23%）. It could be seen that, the quality defects of tobacco could be solved by compound enzyme preparation, and the sensory quality of tobacco could be improved.
