摘要:

为研究不同酶制剂对发酵烟叶的影响,以云南烟叶为试验材料,采用多种酶制剂对烟叶进行酶解处理,并利用葡萄酒果酒酵母菌发酵技术,旨在制备出风味更为丰富饱满的烟叶产品。实验分析了不同酶制剂处理对烟叶常规化学成分、挥发性风味物质及感官品质的影响。结果表明,经过酶解处理,各组烟叶的水分含量和含氮量无较大变化,含氮量大致在0.98%~1.18%,其中100 U·g-1风味蛋白酶处理组烟叶中可溶性总糖和还原糖含量最高,分别为12.11%和5.93%。各组烟叶中挥发性风味物质总量均有所提升,最高为180.029 μg·g-1,而且各组烟叶中主要特征性风味物质含量也得到提升,如新植二烯、苯乙醇、茄酮和巨豆三烯酮等,各组烟叶经酶解处理后感官品质也得到提升。综合分析发现,利用70 U·g-1风味蛋白酶和50 U·g-1 α-淀粉酶复配对烟叶进行酶解处理,可以使烟叶的化学成分更协调,香气成分更充足,感官指标也更好。因此,通过酶解发酵的方式可以提升烟叶的品质,为烟叶的进一步商业化应用提供了依据。

Abstract:

The research aimed to study the influence of different enzyme preparations on fermentation of tobacco. In this experiment, tobacco produced in Yunnan Province were used as materials. Different enzyme preparations were applied to enzymatically treat tobacco, followed by fermentation using wine yeast. The aim was to prepare tobacco products with richer and fuller flavor. The effects of different enzyme treatments on the conventional chemical composition, volatile flavor substances, and sensory quality of tobacco were analyzed. The results showed that, there was no significant change in moisture content and nitrogen content of tobacco after enzymatic treatment, with nitrogen content ranging from approximately 0.98% to 1.18%. The group treated with 100 U·g-1 flavor protease exhibited the highest content of soluble total sugars (12.11%) and reducing sugars (5.93%). The total amount of volatile flavor substances in all groups of tobacco increased, with the highest being 180.029 μg·g-1. Moreover, the content of characteristic flavor substances in each group of tobacco, such as neophytadiene, phenylethanol, solanone, and megastigmatrienone, also increased. The sensory quality of tobacco improved after enzymatic treatment. Comprehensive analysis revealed that enzymatic treatment using 70 U·g-1 flavor protease and 50 U·g-1 α-amylase resulted in a more balanced chemical composition, abundant aroma components, and better sensory indicators of tobacco. Therefore, enzymatic fermentation can improve the quality of tobacco leaves, providing a basis for further commercial development of tobacco leaves.
