Abstract
[Objective] The study aimed to discuss the change law of protein degradation and neutral aroma component in upper leaves of flue-cured tobacco after spraying microbial preparation.[Method] The self-made curing barn with automat-control of temperature and humidity was used to research the effect of spraying microbial preparation with 3 treatments as 40 U/g neutral protease(T1),40 U/g αamylase + glucoamylase+ neutral protease(T2) and 30 U/g special made fermentation liquid(T3) on solubility protein degradation and neutral aroma component in upper leaves in the flue-cured tobacco during baking prophase.[Result] Spraying some dosages of special in 12 h before baking made fermented liquid,neutral protease and the mixture of neutral protease,α-amylase and glucoamylase on the upper leaves of flue-cured tobacco could decrease the solubility protein content in the upper leaves,especially the T2 and T3 had a better results.All the treatments could increase the content of neutral aroma component to some degree,but there was a great difference among the treatments.[Conclusion] T1 and T3 were better on the total amount of neutral aroma component,but T3 was the best on comprehensive effect.
