Changes of Physical and Chemical Properties and Color of Different Varieties of Cigar Leaves during Air-Curing
In order to understand the differences in leaf color change of different varieties of cigar tobac-co during air-curing,this experiment was conducted taking Dexue 1(D1),Dexue 3(D3),Dexue 5(D5)and Chuanxue 3(C3)as the objects.The change characteristics of moisture content,related enzymes activi-ties,plastid pigment content and polyphenol content in leaves of the four varieties of cigar tobacco during air-curing and their effects on the color and quality of tobacco leaves were studied.The results showed that the comprehensive quality of Dexue 3 leaves was the best that had higher enzymes activities,sufficient degradation of polyphenols and plastid pigments,good color and sufficient aroma components after air-curing,which was followed by Dexue 1 and Chuanxue 3.The leaves of Dexue 1 could be used as wrapper.The comprehensive quality of Dexue 5 leaves was the worst.
