摘要
采用电热式温湿自控密集烤烟箱对烤烟上部烟叶在烘烤中细胞壁水解酶和主要组分随温湿度的变化进行了研究。结果表明:果胶甲酯酶(PME)、多聚半乳糖醛酸酶(PG)和纤维素酶在38～48℃酶活性较高。相关性分析表明:PME与纤维素酶呈极显著正相关。烘烤中可溶性果胶含量不断增加,原果胶、总果胶和纤维素含量不断降低,其中果胶(总果胶、原果胶及可溶性果胶)与PG的关系比果胶与PME的关系更密切。
The change pattern of major components and hydrolase in the cell wall of upper tobacco leaves with temperature and humidity during the bulk flue-curing process was studied by using the electric-heated flue-curing barn designed by Henan Agricultural University.The results showed that pectin methylesterase（PME）,polygalacturonase（PG） and cellulase were highly active at 38 to 48 oC.Correlation between PME and cellulase was highly positive significant.During curing,leaf soluble pectin content increased continuously while protopectin,total pectin and cellulose contents decreased continuously.Correlation analysis showed that the relationship of pectin（total pectin,protopectin and soluble pectin） with PG was more closely than that with the PME.
