Description
Technical field:
The present invention relates to utilize biological enzyme technology to handle upper tobacco leaf, particularly relate to a kind of exogenous enzymes treated flue-cured tobacco upper tobacco leaf, to improve the method for upper tobacco leaf quality.
Background technology:
The employed raw material of cigarette enterprise is the sheet cigarette basically at present.The production of sheet cigarette need be passed through processes such as plantation, baking and beating and double roasting; Cycle is longer; Because aspects such as various places ecology, field farming measure and processing technology all exist problem more or less, the sheet cigarette also just exists little or big defective when calling in tobacco productive corporation.At present tobacco productive corporation can only remedy these defectives through the method for the nature ageing in the storehouse basically, and it is satisfied fully that effect can not be made us, and simultaneously because natural ageing generally needed for 2-3 years, also has this mouldy and risk that damage by worms at tobacco leaf during this period of time.Therefore each cigarette enterprise is all eliminated the mass defect of sheet cigarette trying to explore various novel means, and wherein biological enzyme technology is the focus of research.
Publication number is the method that the Chinese patent of CN1030862 discloses a kind of processing inferiority tobacco leaf using microbial compound enzyme; Be sprayed onto the complex microorganism enzyme liquid that contains cellulase, pectase, ligninase and protease on the discarded tobacco leaf after the moisture regain; In humidity 60-70%; Handle 22-26h under 30-50 ℃ of conditions of temperature, the inherent quality of tobacco leaf can promote 0.5-1 level; Publication number is that the Chinese patent of CN1593268 discloses a kind of cigarette with the immobilization biological additive; The emulsion that has prepared the immobilised enzymes that contains degrading proteinase, amylase, pectase, polysaccharide degrading enzyme and cellulase; And be applied in the middle of the ageing processing of redried leaf tobacco; The addition of enzyme is 8%-12%, and degradation temperature is 35-50 ℃, and degradation time is 15-18h; Publication number is that the Chinese patent of CN1723811 discloses a kind of additive for flue-cured tobacco; Be dissolved into PD enzyme, starch degrading enzyme, pectin degrading enzyme, polyphenol oxidase, cellulase, vitamin C and potassium tartrate in the water; Just formed described additive for flue-cured tobacco after the filtration; Before tobacco first baking, under the normal temperature, spray additive for flue-cured tobacco by 0.2%-5% of tobacco leaf weight, the tobacco leaf grade can improve 1-2 levels; Publication number is the method that the application of CN101040723A China discloses a kind of tobacco leaf high-activity bio-enzyme regulator and raising quality of tobacco thereof; Utilize the microbial compound enzyme and the multienzyme active regulator of the plurality of enzymes system of starch-containing enzyme, protease, cellulase and pectase; Handle the discarded tobacco leaf of roasting front and back just with this bio-enzyme regulator, inherent quality can improve 1-2 levels.Above-mentioned disclosed literature content shows the inherent quality of utilizing biological enzyme technology can improve tobacco leaf, becomes enzyme liquid but need prepare when being to use, and the method for using more complicated has increased the water content of tobacco leaf simultaneously, has also just increased the risk of tobacco mildew.
Flue-cured tobacco upper tobacco leaf cell wall substance content is higher; When sucking, be easy to generate withered and burnt smell, flue gas is coarse, excitant is bigger; Regulate the cell wall substance content of upper tobacco leaf if can utilize modern biology enzyme to learn a skill; Promote the Degradation and Transformation of cell wall substance and macromolecular substances, can reduce the assorted gas and the excitant of upper tobacco leaf; Through adding the exogenous enzymes preparation, promote the non-enzyme browning reaction that tobacco leaf is inner, improve the fragrance of tobacco leaf, further improve the industrial applicability of upper tobacco leaf.
Summary of the invention:
For overcoming the defective of prior art; The object of the present invention is to provide a kind of employing mixing enzyme preparation to improve the upper tobacco leaf method for quality; Mainly be to handle the flue-cured tobacco upper tobacco leaf, thereby improve the quality of upper tobacco leaf, improve its use value through the mode of adding enzyme preparation.
