采收时期及调制方式对万源晒烟调制前后氨基酸含量变化的影响
Effect of harvesting time and curing means on variation of amino acid content in Wanyuan sun-cured tobacco before and after curing
摘要
Abstract
Wanmao 3, a major sun-cured tobacco cultivar in Wanyuan of Sichuan, was used in experiments to investigate effects of different harvesting time and curing means on variation of amino acid content in tobacco leaves before and after curing. Amino acids content in tobacco leaf samples were detected before and after curing. Results showed that the total amount of amino acids in tobacco leaves was 147.9 mg/g before curing. Glutamic acid and aspartic acid content were the most abundant, accounting for 12.5% and 10.7% of the total amino acids, respectively. Total amount of amino acids in tobacco leaves decreased by 29.7% to 104.0 mg/g after curing. Aspartic acid content increased significantly, an increase of 28.9%, accounting for 23.6% of the total amount of amino acids. Glutamic acid and other amino acids decreased significantly. Harvesting time and curing means were proved to have significant effect on amino acids content. Under air-curing conditions, the total amount of amino acids continued to increase with delayed harvesting time, while under sun-cured conditions amino acid content first increased and then decreased. Curing means had significant influence on aspartic acid content. When the maturity of tobacco was low, the content of aspartic acid in sun-cured tobacco leaves was higher than that in air-cured tobacco leaves, while when the maturity was high, the opposite trend was observed.关键词
