Method for preparing cigar tobacco leaves by means of fermentation effect of compounded enzyme preparation

The invention discloses a method for preparing cigar tobacco leaves by means of the fermentation effect of a compounded enzyme preparation. Petioles, of tobacco leaves, which are subjected to a moisture regaining process are arranged in a compounded enzyme preparation aqueous solution for 10-30 minutes, the compounded enzyme preparation aqueous solution is sprayed on the tobacco leaves, the weight ratio of the compounded enzyme preparation aqueous solution to the tobacco leaves is 1:5-15, the tobacco leaves the water content of which is 25+/-1% are fermented for 10-60 days under the conditions that the temperature is 45-55 DEG C and the humidity is 65-75%, and the cigar tobacco leaves are obtained. According to the invention, the biological enzyme preparation and the raw materials of the cigar tobacco leaves are fermented at the same time, on the premise that a traditional flavouring manner is not used, the product quality is changed, and the tobacco leaves processed by the above processing technology are advantaged in that the bitter taste is obviously reduced, the characteristics such as flavor, smoke, taste, combustibility and grayness are all improved, and the quality of the cigar tobacco leaves is improved.
