摘要
Abstract
Chlorophyll-a and chlorophyll-b content and the dynamic of lipoxygenase activity, which are important to sensory quality of yellow sun-cured tobacco, were studied by using different curing methods. Results indicated that flue-curing measure could increase Lipoxygenase activity and bulking measure could extend effective time of Lipoxygenase. There was a significant negative correlation between lipoxygenase activity and chlorophyll-a, chlorophyll-b content respectively. Degradation rate of chlorophyll reached up to 90%when treated with yellow sun-curing, flue-curing and bulking measures. Bulking measure was the best as chlorophyll content reached 0.05 mg•g-1DW and its degradation rate was 97.73%.关键词
