Effect of Different Air-curing Humidity on Organic Acid Content of Burley Tobacco
-
摘要: 在白肋烟的晾制过程中设置不同的湿度环境,探究调制环境对白肋烟有机酸含量的影响,为提高白肋烟的内在品质提供基础。试验设置4个不同的湿度条件,结果表明:在低湿条件下20种有机酸总含量最高,除去柠檬酸,其余19种有机酸的总量在中湿条件下为最大。半挥发性有机酸以及高级脂肪酸的含量,随着晾制湿度从低湿—中湿—高湿—对照(比高湿湿度还大)的变化逐渐降低;某些挥发性有机酸随着湿度的升高难以测定出来;非挥发性有机酸除苹果酸和柠檬酸以外,以中湿晾制条件下最高。柠檬酸以中湿处理最低,苹果酸以低湿处理最高。Abstract: Four humidity levels were applied to air-curing of burley tobaccoto for comparing the effect of curing environment on organic acid content in burley tobacco.The results showed that the highest content of total 20 organic acids was in the lowest humidity level,while with exception of citric acid,the highest content of rest organic acids was found in the middle level of humidity.The content of semi-volatile organic acids and aliphatic acids were decreased following the humidity level increased from low,middle and high to control as the highest humidity applied in air-curing.Some volatile organic acid were undetectable concomitant with the humidity increasing.The content of nonvolatile organic acids was detected the highest in middle humidity of air-curing but the content of citric acid was the lowest.In addition,the highest of malic acid content was found in low humidity curing.
