摘要: 选择3种清香型产地复烤烟叶,分别用2%以下氧浓度、6%~8%氧浓度和21%氧浓度气调养护醇化,分析烟叶采用3种气调方式醇化时化学成分的含量变化差异。结果表明,随着醇化进行,总植物碱含量变化较小,pH、多酚含量、氨基酸含量呈下降趋势,两糖比逐步上升;3种气调方式中,pH下降幅度、多酚消耗率和氨基酸消耗率均表现为21%氧浓度>6%~8%氧浓度>2%以下氧浓度,21%氧浓度气调的化学成分变化波动最大,2%以下氧浓度气调波动相对平缓;在高温季节,pH变幅、多酚消耗率、氨基酸消耗率都有一个加速变化的过程;3种清香型烟叶因为产地不同,常规化学成分差异较大,云南普洱B1F(A)烟叶、四川西昌B1F烟叶的pH、多酚含量和氨基酸含量明显大于福建龙岩B1F(A)烟叶。

Abstract: Three fresh-flavor tobacco leaves were selected and alcoholized by below 2% oxygen concentration, 6%~8% oxygen concentration and 21% oxygen concentration, respectively. The difference in the content of chemical composition of tobacco leaves were analyzed. The results showed that, with the alcoholization, the content of total alkaloids changed little, pH, polyphenols and amino acids decreased, and the ratio of two sugars increased gradually. Among the three controlled atmosphere methods, pH decline range, polyphenol consumption rate, amino acid consumption were manifested as 21% oxygen concentration>6%~8% oxygen concentration > below 2% oxygen concentration. The chemical composition change of 21% oxygen concentration controlled atmosphere was the largest, and the fluctuation of below 2% oxygen concentration controlled atmosphere was relatively gentle. In high temperature season, pH, consumption rate of polyphenols and amino acids all had a process of accelerating change. Because of the different producing areas, the conventional chemical composition of the three kinds of fresh-flavor tobacco leaves were quite different, pH, polyphenol content and amino acid content of B1F (A) tobacco leaves from Pu’er city of Yunnan province and Xichang city of Sichuan province were significantly higher than those from Longyan city of Fujian province.

Key words: controlled atmosphere and alcoholization, fresh-flavor tobacco leaf, oxygen concentration, chemical composition
