贵州中烟工业有限责任公司项目“烟叶醇化过程质量研究”（12121）；

本校为第一机构

为探究不同仓贮环境及不同产地片烟蛋白质及氨基酸含量的变化规律,以位于贵州兴义、贵阳和贵定的3个醇化库中6个产地片烟为材料,对醇化片烟的蛋白质、游离氨基酸和游离脯氨酸含量进行了动态变化分析。结果表明:(1)片烟醇化过程中,3个醇化库不同产地片烟的蛋白质含量持续下降,游离氨基酸含量在醇化12个月内上升,但醇化12个月后下降;(2)醇化过程中片烟游离脯氨酸含量持续升高,与游离氨基酸总量呈现不同的变化趋势,所以醇化片烟中脯氨酸氧化分解较少。(3)醇化6~18个月时,清香型和中间香型片烟蛋白质含量的变化幅度存在显著差异,但浓香型片烟的蛋白质含量变化幅度均差异不显著;醇化12~18个月时,浓香...

The dynamic changes of proteins, free amino acids and proline in tobacco strips from six producing areas located in three aging storehouses of Xingyi, Guiyang and Guiding, which belong to China Tobacco Guizhou Industrial Co., Ltd, were analyzed to study the patterns of changes of protein and free amino acid contents of tobacco strips under different storing conditions and from different producing areas. The results showed that: (1) During the aging process, the protein content of tobacco strips in different producing areas of three aging storehouses declined consistently. The content of free a...
