Abstract

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.

Description

Utilize the method that cigar tobacco is prepared in compounded enzyme preparate fermentation
Technical field
The present invention relates to cigar manufacture field, utilize compounded enzyme preparate to ferment in particular to one The method preparing cigar tobacco.
Background technology
Cigar tobacco leaf raw material has sugared nitrogen than low feature, the meeting when burning and sucking of usual glucide Producing acidic materials, nitrogen substance can produce alkaline matter when burning and sucking, and cigar is when burning and sucking Owing to acid base imbalance can produce the most pungent, pained sensation, affect product sales volume.
The ultimate constituent of raw tobacco material contains cellulose, pectin, starch, protein, but It is that the sucking quality of tobacco product is adversely affected by the most to a certain extent.Enzyme Cellulose, pectin, starch, protein degradation can be little molecule thing by preparation under suitable conditions Matter, such as monosaccharide, oligosaccharide, enzyme preparation, peptides.These catabolites the most inherently wind Taste material, on the other hand can be converted into flavor components by Maillard reaction.There are some researches show, In cigarette combustion process, unreacted saccharide completely can be transferred directly in main flume, and this Transfer likely can bring " sweet ", " promoting the production of body fluid " and the mouthfeel of " aftertaste " for Medicated cigarette.Nicotiana tabacum L. During modulating, be aged, process and burning and sucking, all along with non-enzymatic brown in various degree Change reaction, produce many flavor components.
Biological enzyme technology has been widely applied to each neck such as medicine, food fermentation and feedstuff at present Territory.But, the most do not utilize enzyme preparation to improve grinding of cigar raw material this respect Study carefully.
Summary of the invention
The technical problem to be solved is just to provide one and utilizes compounded enzyme preparate to ferment The method preparing cigar tobacco.The method prepares cigar tobacco and overcomes because of cigar cigarette Leaf raw material sugar nitrogen than low, alcoholization the cycle long;Sugar nitrogen than low Nicotiana tabacum L. when burning and sucking due to soda acid not Balance can produce pungent, pained sensation, and the shortcoming affecting product sales volume, by compound enzyme system Agent fermentation reduces the content of unfavorable composition in Nicotiana tabacum L., is allowed to be converted into beneficially Nicotiana tabacum L. and inhales the thing of taste Matter, Balancing degree, effectively improves the quality that burns and sucks of Nicotiana tabacum L., improves the use value of Nicotiana tabacum L..
For achieving the above object, the one that the present invention provides utilizes combined enzyme fermentation preparation snow The method of eggplant Nicotiana tabacum L., comprises the following steps:
1) under field conditions (factors), the former Nicotiana tabacum L. of cigar is refined, and under vacuum to former Nicotiana tabacum L. Carry out moisture regain process;
2) 15~the fiber of the α-amylase of 25%, 15~25% are weighed than meter by weight percent Element enzyme, 15~the peroxidase of the pectase of 25%, 1~5%, remaining is flavor protease; Mix homogeneously, obtains compound enzymic preparation, standby;
3) by step 2) compound enzymic preparation that obtains is dissolved in water or lemon that pH value is 6.0~7.0 In lemon acid-sodium citrate buffer solution, it is uniformly mixed, obtains compound enzymic preparation solution;
4) by step 1) moisture regain process Nicotiana tabacum L. petiole end be placed in compound enzymic preparation aqueous solution Leaching handle 10~30min, then by weight 1 5~15 by compound enzymic preparation solution spray On Nicotiana tabacum L., obtain the Nicotiana tabacum L. containing compound enzymic preparation;Standing makes water balance in Nicotiana tabacum L., then The moisture content of regulation Nicotiana tabacum L. is to 25 ± 1%;
5) Nicotiana tabacum L. that moisture content is 25 ± 1% is placed in temperature be 45~55 DEG C, humidity be Ferment 10~60 days under conditions of 65~75%;Obtain cigar tobacco.
Leaching handle will be immersed in the water by Nicotiana tabacum L. pommel, and Nicotiana tabacum L. is vertically placed, and water flows to cigarette by petiole Leaf offshoot, enters inside Nicotiana tabacum L..Cigar tobacco first soaks handle in the solution, opens from petiole in Nicotiana tabacum L. Beginning to grow and have the vein led to everywhere, solution enters inside Nicotiana tabacum L. from Nicotiana tabacum L. shank, enters it deep Place reacts;Tobacco leaf surface spray solution later, the solution of tobacco leaf surface is from Nicotiana tabacum L. outer surface Pore enters inside Nicotiana tabacum L., will react through Surface absorption.During two kinds of Nicotiana tabacum L. solution process: Leaching handle contact range is little, but solution can reach Nicotiana tabacum L. vein depths;Surface sprinkling makes Nicotiana tabacum L. contact Solution range is big, but processes only Nicotiana tabacum L. top layer and cannot arrive depths.By Nicotiana tabacum L. first carry out soak handle, Spraying on surface, the two combines and makes solution by Nicotiana tabacum L. either range or the degree of depth again All fully absorb.
Further, described step 2) in, compound compound enzymic preparation is by weight percent than meter α-amylase by 20%, the cellulase of 20%, the pectase of 20%, the peroxidating of 5% Thing enzyme, the flavor protease of 35%.
Yet further, described step 3) in, water is deionized water or pure water.
Yet further, described step 4) in, the content of each component enzymes in detection Nicotiana tabacum L., and Make in every gram of Nicotiana tabacum L. containing compound enzymic preparation, α-amylase, cellulase, pectase, wind The enzymatic activity of taste protease and peroxidase be respectively 3~7.5U, 15~60U, 50~100U, 100~150U and 0.4~0.6U.
Yet further, described step 4) in, compound enzymic preparation aqueous solution and the weight of Nicotiana tabacum L. Ratio is 1 10.
Yet further, described step 4) in, every gram contains in the Nicotiana tabacum L. of compound enzymic preparation, The enzymatic activity of α-amylase, cellulase, pectase, flavor protease and peroxidase is divided Wei 5U, 45U, 75U, 120U and 0.5U.
Yet further, described step 4) in, the time of standing is 12~24h.
The beneficial effects of the present invention is:
The present invention uses biological enzyme formulation and cigar tobacco raw material co-fermentation, is not using tradition Change product quality on the premise of perfuming mode, the Nicotiana tabacum L. after processing by processing technique of the present invention, Bitterness improves substantially, obtains in odor characteristic, smoke transportation, taste characteristics, flammability and Lycoperdon polymorphum Vitt Being improved on Fen, quality significantly improves.
