Problems solved by technology

[0003] In the currently published patents, many paper-making tobacco sheet manufacturing technologies use direct solvent extraction methods. However, tobacco stems and other substances in the raw materials contain more difficult-to-extract harmful substance precursors than tobacco leaves, including protein , pectin, cellulose, lignin and other macromolecular substances will produce a strong irritating feeling during the combustion process
During the burning process of protein, alkaline substances such as pyrrole, pyridine, alkaloid, ammonia and other irritating and pungent substances will be produced, which will bring irritating and spicy feeling to cigarettes; Irritant, carcinogenic methanol, formaldehyde and other substances; lignin not only seriously affects the color of the flakes, but also produces phenolic compounds during the combustion process, which brings acrid and burning sensations to the mouth, making the taste worse
At present, there are patents that use acid protease, cellulase and pectinase to degrade macromolecular substances in raw materials through enzymatic hydrolysis and extraction. However, the enzyme itself remains as a protein macromolecule in the enzymolysis solution and becomes an exogenous impurity protein, which affects Tobacco flake quality

Abstract

The invention discloses a method for preparing a tobacco sheet through an enzymolysis extraction-Maillard reaction composite technology. The method comprises the following specific steps: carrying out enzymolysis extraction simultaneously on tobacco powder in water, carrying out solid-liquid separation, concentrating the enzymolysis liquid, adding with reducing sugar and amino acid and carrying out Maillard reaction at 70 DEG C, uniformly coating paper base with the reaction liquid, drying, and shredding, and thus obtaining the tobacco sheet. With the adoption of the enzymolysis extraction-Maillard reaction composite technology, the advantages of the preparing process of the tobacco sheet through the paper-making process are exerted, meanwhile, the two technological means of the enzymolysis and the Maillard reaction are comprehensively utilized, so that the extraction efficiency of the tobacco aroma materials is improved, and moreover, the chemical components of tobacco are selectively changed, so that the purposes of aroma enhancement and harm reduction are achieved, and therefore, the method has the incomparable advantages.

Description

technical field [0001] The invention belongs to the technical field of tobacco sheet production, and in particular relates to a method for preparing tobacco sheet by enzymolysis extraction-Maillard reaction composite technology. Background technique [0002] Tobacco sheet is a product of tobacco resources recycling, and it is a cigarette filler made by recycling tobacco processing waste. The papermaking method is an important method for the production of tobacco flakes. The paper base is made through the steps of extraction, concentration, separation, beating, refining, papermaking, and drying, and then tobacco flavor is coated on the paper base to make tobacco flakes. . Paper-making tobacco sheet not only has advantages in improving the structural strength and combustion performance of tobacco leaf products and reducing the amount of nicotine and tar in cigarette smoke, but also reduces the unit consumption of tobacco leaves and saves production costs. [0003] In the cur...
