为提高晒黄烟的品质和安全性, 全面系统地把握氮代谢在调制过程中的变化规律, 研究了不同调制措施对晒黄烟调制期间主要含氮化合物变化规律的影响.结果表明:总氮含量在晒制的前9 d呈下降趋势, 9 d之后稍有上升, 总体上变化不大;可溶性蛋白主要在晒制前期和中期发生降解;游离氨基酸含量呈先增加后降低的“单峰曲线”, 积累速度表现为“快-慢-快”的变化规律;晒制期间生物碱含量变化不大, 硝酸盐最终含量低于开始晒制时.不同调制措施相比, 划筋处理水分散失较快, 有助于可溶性蛋白的充分降解, 游离氨基酸的积累和硝酸盐的合理转化.“,”In order to improve the quality and safety of yellow sun-cured tobacco, and grasp the change rule of nitrogen metabolism comprehensively and systematically in the curing process, this paper studied the effects of different curing methods on nitrogen compounds in yellow sun-cured tobacco during curing stage. The results showed that the total nitrogen content declined 9 d ahead of curing process, then slightly increased, but there were not many changes. Soluble protein was degraded mainly during the prophase and metaphase of the curing. The content of free amino acid increased first then decreased, and the accumulation speed showed the changing rule of“fast-slow-fast”.The content of alkaloids changed a little during the curing process. The final content of nitrate was lower than that in the beginning of curing. Compared with different curing measures, the treatment of water loss contributed to the full degradation of soluble protein, accumulation of free amino acids and rational transformation of nitrate.
