Problems solved by technology

[0009] The purpose of the present invention is to overcome the sensory quality problems such as low internal quality, insufficient aroma, heavy miscellaneous gas, and large irritation that are common in the existing domestic papermaking reconstituted tobacco leaves, and to provide a method for reconstituted tobacco using microbial fermentation of crude enzyme liquid. Tobacco leaf raw materials and slurry, and a biological treatment method for improving the sensory quality of reconstituted tobacco leaves by papermaking method, the finished product of reconstituted tobacco leaves by papermaking method after treatment by this method has good internal quality, less miscellaneous gas, and less irritation; Enzymatic refining and enzymatic beating are carried out through the synergistic action of two kinds of biological enzymes, the fiber characteristics of the pulp, the physical properties of the sheet base and the energy consumption of refining have all been improved.

Embodiment 1

[0054] Weigh 50 parts of tobacco stems and 50 parts of tobacco dust (including 40 parts of tobacco leaf fragments and 10 parts of tobacco dust) according to the absolute dry weight (ie weight), and perform a water extraction respectively. The technical conditions for primary extraction of tobacco stems are solid-liquid ratio of 1:8, temperature of 70°C, and time of 50 minutes. The primary extraction process conditions of tobacco raw materials such as tobacco leaf fragments and tobacco powder are as follows: temperature 60°C, solid-liquid ratio 1:5, and time 50 minutes. The dryness after one-time extraction and squeezing of tobacco stems is 25%, the dryness of tobacco leaf fragments and tobacco dust after one-time extraction and squeezing is 30%, the yield of tobacco stem extract is 45%, and the extraction of tobacco leaf fragments and tobacco dust The yield of the product is 50%.

[0055] After the tobacco stems are extracted once, they are processed by rubbing. After rubbing...

Embodiment 2

[0062] Compared with Example 1, only the following treatment methods are changed in this embodiment, and other treatment conditions are unchanged: the amount of fermented crude enzyme liquid of white rot fungus is changed to 25 IU / g, and the amount of fermented crude enzyme liquid of Schizophyllum fermented to 50 IU / g. Except for the above-mentioned changes in the treatment conditions, other treatment conditions remained unchanged, and the scheme of Example 1 was repeated, and the final sensory evaluations obtained are shown in Table 2. After adopting the two biological treatment schemes of this example, the cigarette has a sufficient aroma, with a roasted aroma, a slight woody smell mixed into the aroma, a better sweetness, a more transparent smoke aroma, and a cleaner mouth.

Embodiment 3

[0064] Change the amount of white rot fungus fermented crude enzyme liquid to 50IU / g, the amount of Schizophyllum fermented fermented crude enzyme liquid to 10IU / g, and other treatment conditions remain unchanged, that is, the same as Example 1, repeat the scheme of Example 1, and finally obtain See Table 2 for sensory evaluation.

Abstract

The invention discloses a biological treatment method of papermaking-method reconstituted tobacco raw materials and pulp, biological treatment is conducted twice on the papermaking-method reconstituted tobacco raw materials and pulp by means of the crude enzymes obtained through microbial fermentation, the object for the first biological treatment is materials which are extracted and tread rolled, and biological enzymes degrade cell wall substances and plays a role of enzymatic pulping; the second biological treatment is conducted in the potential elimination process after high consistency pulping is conducted and before low consistency beating is conducted, and the biological enzymes are acted on pulp fibers, further efficiently degrades macromolecular substances such as lignin, cellulose, hemicellulose, pectin and protein, conducts decoration or modification on the fiber surfaces, and plays the role of enzymatic beating. After the biological treatment is conducted twice, the cell wall substances in the materials and the pulp and undissolved macromolecular substances are degraded effectively, and the sensory quality of papermaking-method reconstituted tobaccos is promoted obviously.

Description

technical field [0001] The invention relates to the technical field of papermaking reconstituted tobacco production technology, in particular to a biological treatment method for papermaking reconstituted tobacco raw materials and slurry. Background technique [0002] Papermaking reconstituted tobacco, originally a recycling of tobacco waste, has been developed as a way to improve the chemical and taste qualities of cigarettes. With the increase in the blending ratio of reconstituted tobacco leaf products in Chinese-style cigarette formulas, the comprehensive effect of paper-making reconstituted tobacco leaves on reducing harm, reducing coke, reducing consumption and improving quality of Chinese-style cigarettes has become increasingly prominent. The manufacturing process of reconstituted tobacco leaves by papermaking method at home and abroad includes raw material extraction, concentration, pulping, papermaking, coating, drying and other processes. Although domestic produc...
