摘　　要：为了明确在不同地域气候环境条件下自然醇化和密封降氧醇化的规律及差异,将云南普洱2个等级片烟分别放置在广州和昆明两地同步醇化,在广州采用自然醇化和2%以下氧体积分数密封降氧醇化,在昆明仅采用自然醇化的方式。通过定期取样,分析两地醇化片烟的外观质量、感官质量和化学成分的差异。结果表明:(1)在醇化处理的23月内,广州自然醇化和密封降氧处理的普洱烟叶总植物碱、总糖、多酚和氨基酸的质量分数均随醇化的进行而下降,两糖比升高,片烟品质在醇化的第10~13月达到最佳。(2)昆明自然醇化的片烟在整个试验期内,各化学成分的变化幅度较为平缓,片烟品质随醇化时间的延长逐步上升。(3)广州储存库的高温环境有利于片烟快速醇化,密封降氧处理能在一定程度上提高片烟的品质;而昆明储存库更适合片烟缓慢醇化,片烟在醇化过程中化学成分的变化明显慢于广州。In order to clarify the rules and differences of natural aging and sealed aging at lower oxygen concentration under different regional climatic conditions,tobacco strips of two varieties from Pu’er region in Yunnan Province were synchronously aged in Guangzhou and Kunming.In Guangzhou,natural aging and sealed aging at less than 2%oxygen concentration were used,while only natural aging was used in Kunming.The differences in leaf appearance,sensory quality and chemical components of the strips aged in the two cities were analyzed by periodic sampling.The results showed that:1)The mass fractions of total alkaloids,total sugars,polyphenols and amino acids of the naturally and sealed aged Pu’er tobacco in Guangzhou decreased over the 23-month aging period,the reducing sugar/total sugar ratio increased,and the optimum quality of the strips reached after aging for 10-13 months.2)The variations in the chemical components of the naturally aged strips in Kunming were relatively small throughout the experimental period,and the quality of the strips gradually increased with the progress of aging.3)The high-temperature environment of the warehouses in Guangzhou was conducive to the rapid aging of the tobacco strips,and the sealed deoxidization treatment improved the quality of the tobacco strips to a certain extent.The warehouses in Kunming were more suitable for the slow aging of tobacco strips,and the variations in the chemical components of tobacco strips during aging were significantly smaller than those in Guangzhou.
