摘要
为探索烘烤后烟叶最佳储藏醇化技术和改善烟叶品质,进行了不同储藏醇化措施对保山龙川江流域烟包内温湿度及烟叶外观品质、化学成分和感官品质的影响试验。结果表明:1黑膜覆盖+喷施混合酶制剂(T6)处理、黑膜覆盖(T5)和白膜覆盖(T4)处理的烟包内烟叶含水率和湿度显著低于不覆盖(CK,T1)、麻片覆盖(T2)和草席覆盖(T3)处理,烟包内温度略高于CK,T2和T3处理。2烟叶经过90 d储藏醇化后,T6处理的烟叶表现为颜色略有加深,青色略微减弱,色度增强,外观品质有所改善。3T6处理烟叶化学成分在混合酶制剂催化作用下,总糖、总氮、蛋白质含量(质量分数)略有降低,还原糖含量(质量分数)略微升高,烟叶化学成分趋于协调。4T6处理90 d后,烟叶香气质、香气量、杂气、余味等指标明显优于CK,T2和T3处理,烟叶感官品质明显提高。
To explore the optimal storage and aging measures for flue-cured tobacco leaves and improve tobacco quality, an experiment was carried out to study the effects of different storage and aging measures on the temperature and humidity inside tobacco bales and the appearance quality, chemical composition and sensory quality of tobacco at Longchuan River basin in Baoshan. There were six treatments： Treatment 1, uncovered tobacco leaves （CK, T1）; Treatments 2, 3, 4, 5, tobacco leaves packed by linen cloth （T2）, straw mat （T3）, white film （T4） and black film （TS）; Treatment 6, tobacco leaves sprayed with a mixed enzymatic agent and packed by black film （T6）. The results showed that： 1） The moisture content in leaves and the humidity inside bales of T6, T5 and T4 were significantly lower than those of T1, T2 and T3, while the temperature inside bales of T6, T5 and T4 was slightly higher than that of the other three treatments. 2） After treatment for 90 days, the leaf color of T6 turned dark slightly, green faded somewhat, chromaticity enhanced, and appearance quality was improved to a certain extent. 3） Under the catalysis of mixed enzymatic agent, the contents of total sugar, total nitrogen and protein in leaves of T6 reduced slightly, while reduce sugar increased somewhat, and chemical composition tended to be harmonious. 4） After treatment for 90 days, the aroma quality, aroma quantity, offensive odor and aftertaste of leaves of T6 were obviously better than those of T1, T2 and T3; the sensory quality was obviously improved by T6.
