The present invention will be described in more detail below.
At present some area institute tobacco leaves that produce are burnt fragrant and sweet too outstanding, affect the harmony of mouthfeel and integral body, study to show in this and tobacco leaf that total sugar content is too high and have a direct relation.
The present invention proposes a kind of method that reduces tobacco leaf total reducing sugar, and the step of described method is as follows:
A, at 35～90 ℃ of temperature, tobacco leaf is processed 1-35min according to the volume ratio 1:20 of its weight and water～240g/ml, obtains the solidliquid mixture that a kind of pH value is 5.5～6.0.
According to the present invention, described tobacco leaf obtains after just roasting, redrying, alcoholization, for example, buy the tobacco leaf product from Yunnan.
Described tobacco leaf process at 35～90 ℃ is soaked (or spray), if this temperature, lower than 35 ℃, will be unfavorable for the stripping of total reducing sugar in tobacco leaf; If described tobacco leaf soaks or sprays treatment temperature higher than 90 ℃, the excessive stripping of total reducing sugar in tobacco leaf, other solable matter of while is a large amount of strippings thereupon also, thereby destroy the fragrance of tobacco leaf itself.
Particularly preferably, described tobacco leaf immersion (or spray) temperature is 40～60 ℃.
Suitable soak time is conducive to the total sugar substance in stripping tobacco leaf.If the processing time of steps A is too short, in tobacco leaf, total reducing sugar is difficult for stripping; If described tobacco leaf soaks or the spray processing time is long, also can cause the excessive stripping of total reducing sugar in tobacco leaf, and a large amount of strippings of other solable matter, thereby the fragrance of destruction tobacco leaf itself.Particularly preferably, described tobacco leaf immersion or spray processing time are 8～12min.
In this step, pH value during immersion treatment is not very crucial, and the normally used pH value of the art is 5.5-6.0, can add citric acid to regulate by the solidliquid mixture to steps A, when citric acid adds when too much, can be by adding NaOH to regulate pH value.。
According to preferred embodiment a kind of, in steps A, the weight of tobacco leaf and the volume ratio of water can be 1:20～1:50g/ml.
