Application of flavourzyme for fermenting and upgrading a cigar

Abstract

The invention discloses an application of flavourzyme for fermenting and upgrading a cigar. The process of the application comprises following steps: a. humidifying naturally-aged cigar tobacco until the water content of the cigar tobacco reaches 15-16%, and soaking the petiole of the cigar tobacco into an enzyme solution prepared from the flavourzyme and water or a buffer solution for 10-30 minutes, wherein the flavourzyme activity in the enzyme solution is 1250-1750 U / ml; b. uniformly spraying the enzyme solution on the cigar tobacco, wherein the mass ration of the enzyme solution to the cigar tobacco is 1:8-12; and c. allowing the cigar tobacco to stand for 12-24 hours, adjusting the water content of the cigar tobacco after water balance is achieved, and then fermenting the cigar tobacco. After the cigar tobacco is processed through the process provided by the invention, the bitter taste of the cigar is obviously improved, the fragrance, the smoke component, the taste, the combustion performance and the grayness of the cigar are improved, and the quality of the cigar is improved.

Description

technical field [0001] The invention relates to the field of tobacco processing, in particular to the application of a flavor protease in the fermentation and quality improvement of cigar tobacco. Background technique [0002] Protein is the basic component of tobacco leaves. Its hydrolyzed products and further transformed products are the original substances of many tobacco aroma substances, but high protein content will produce a protein odor like burning feathers when smoking, and will also reduce the quality of tobacco leaves. Combustibility, and is the precursor of harmful substances in the smoke, including quinine, HCN and other nitrogen-containing compounds, which seriously affect the flavor quality and safety of tobacco leaves. [0003] At present, the most reported method for degrading excess protein in tobacco leaves is enzyme treatment. The enzymes used include neutral protease, acid protease, alkaline protease, papain, etc., among which neutral protease has a bet...

AI Technical Summary

Problems solved by technology

Because cigar tobacco leaves have the characteristics of low sugar-to-nitrogen ratio and high protein content, ordinary protease treatment methods are not suitable, and cannot fully decompose the protein in cigar tobacco leaves

Moreover, at present, almost all proteases act on tobacco leaves by making a solution and spraying them directly. The enzyme in the solution enters the tobacco leaves through the pores on the surface of the tobacco leaves, and can only process the surface protein of the tobacco leaves but cannot reach the depth. Due to the high protein content of cigar leaves The particularity of tobacco leaves, a large amount of protein deep inside the tobacco leaves cannot be decomposed into small molecules, which will affect the aroma and taste, make the aroma quality worse, and increase the irritation
