Problems solved by technology

These methods mainly change the air permeability of paper by adding exogenous substances through physical methods, and provide "oxygen source" to oxidize CO into CO. 2 Or it can act as an adsorption function to reduce the release of CO, and the introduction of alkali metals, chloride ions, and nanomaterials may not only affect the quality of the product, but also pose a problem for safety.

Embodiment 1

[0016] The lignin compound enzyme is prepared, and its component and mass ratio is lignin peroxidase (Lip): manganese peroxidase (Mnp): laccase (Lac)=1:1:2. Add lignin compound enzyme to the pulping section of tobacco pulp produced by papermaking method to reconstitute tobacco leaves to enzymatically hydrolyze the pulp. The enzymatic hydrolysis conditions are: the concentration of tobacco pulp is 3% (100kg dry weight), and the degree of beating is 25. ° SR, the amount of enzyme added is 300u / g, the enzymolysis temperature is 35°C, and the reaction is carried out under stirring for 0.5 hours, 1 hour, and 2 hours (i.e. the enzymolysis time). The lignin compound enzyme slurry was used as a parallel control sample. The slurry with low lignin content obtained after enzymatic hydrolysis is copied into a substrate according to the prior art method, and then coated and dried to obtain a low-CO reconstituted tobacco product, which is cut into shreds and rolled into reconstituted tobacc...

[0020] The lignin compound enzyme is prepared, and its component and mass ratio is lignin peroxidase: manganese peroxidase: laccase=1:3:0.5. Add lignin compound enzyme to the pulping section of tobacco pulp produced by papermaking method to reconstitute tobacco leaves to enzymatically hydrolyze the pulp. The enzymatic hydrolysis conditions are: the concentration of tobacco pulp is 1% (absolute dry weight 100kg), and the degree of beating is 32. ° SR, the amount of enzyme added is 300u / g, 600u / g, 900u / g respectively, the enzymolysis temperature is 25°C, and the reaction is stirred for 2 hours. After the reaction, the slurry is dried to measure the lignin content. The material is a parallel control sample. The slurry with low lignin content obtained after enzymatic hydrolysis is made into a substrate, coated and dried to obtain a low-CO reconstituted tobacco leaf product. Shred the reconstituted tobacco leaf products, roll them into reconstituted tobacco leaf cigarettes (the we...

Embodiment 3

[0024] The lignin complex enzyme is prepared, and its component and mass ratio is Lip:Mnp:Lac=1:5:4. Add lignin compound enzyme to enzymatically hydrolyze the pulp of tobacco pulp produced by papermaking reconstituted tobacco leaves. The enzymatic hydrolysis conditions are: the concentration of tobacco pulp is 5% (100kg dry weight), and the degree of beating is 18. ° SR, the amount of enzyme added is 600u / g, and the reaction is stirred at 25°C, 35°C, and 45°C respectively. The reaction time is the enzymolysis time of 2 hours. The compound enzyme slurry was used as a parallel control sample. The slurry with low lignin content obtained after enzymatic hydrolysis is made into a substrate, coated and dried to obtain a low-CO reconstituted tobacco leaf product. Shred the reconstituted tobacco leaf products, roll them into reconstituted tobacco leaf cigarettes (the weight of a single cigarette sample is 0.8±0.03), equilibrate overnight at a constant temperature of 23±1°C and a cons...

Abstract

The invention discloses a method for reducing the smoke CO (carbon oxide) release amount of paper-making reconstituted tobaccos. The method comprises the steps as follows: a lignin complex enzyme is added in either processing period of a tobacco pulping period and pulp forming period during paper-making reconstituted tobacco production to perform enzymolysis on pulp, so that pulp with lower lignin content is obtained; the pulp with low lignin content after enzymolysis is subjected to paper making to form substrates, coated and dried to obtain a reconstituted tobacco product with low CO; the lignin complex enzyme contains Lip, Mnp and Lac, a complex enzyme mass ratio of Lip, Mnp to Lac is 1: (1-5): (0.5-4); and the enzymolysis condition is that the dosage of complex enzyme is 300 u / g-900 u / g in terms of oven dry of tobacco pulp, the enzymolysis temperature is 25-45 DEG C, the enzymolysis time is 0.5-2 hours, the tobacco pulp concentration is 1%-5%, and the beating degree of the pulp ranges from 18-degree SR to 32-degree SR. According to the invention, the ligninase enzymolysis method is adopted to degrade lignin which is a CO precusor substance in tobacco fiber, so that the reconstituted tobacco smoke CO release amount and influence of offensive lignin odor to reconstituted tobacco smoking quality can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of tar reduction and harm reduction of reconstituted tobacco leaves by a papermaking method, and in particular relates to a method for reducing the content of lignin, a precursor of CO, to reduce CO emission. Background technique [0002] At present, more and more attention has been paid to the safety of smoking in the society. As an important means of reducing tar and harm, reconstituted tobacco leaves are gradually increasing in cigarettes. Therefore, the development of reconstituted tobacco products with low hazards has gradually attracted attention. At present, reconstituted tobacco leaves have the characteristics of high carbon monoxide (CO) and low tar. Even if more of this product is used in cigarette formula to reduce tar, it may still cause the CO emission of cigarettes to exceed the industry's limit standard. CO is a major harmful component in cigarette smoke and belongs to one of the harmful compo...
