Problems solved by technology

In addition, paper-making tobacco flakes also have the advantages of low density, high filling value, and good combustibility. However, in the traditional paper-making flake production process, in order to ensure that the flake has a basic skeleton structure, a large proportion of wood pulp fibers, which will reduce the smoking quality of the sheet, such as increasing the irritation of the sheet, aggravating the prickly feeling and miscellaneous gas, etc., thus limiting the large-scale application of paper-making sheets in cigarettes

Embodiment 1

[0066] Embodiment 1: Water-soluble low degree of polymerization biological polysaccharide

[0067] The steps of preparing water-soluble low degree of polymerization biological polysaccharide are as follows:

[0068] (1) After cleaning the lobster shrimp skin, dry it at a temperature of 100° C. for 30 minutes, then select the DJ-02 type crushing equipment produced by Shanghai Dianjiu Traditional Chinese Medicine Machinery Manufacturing Co., Ltd. to crush it to 50 mesh, and soak it in 6% by weight hydrochloric acid aqueous solution for 30 minutes , then washed with water until neutral, dried, and then placed in a RAT type double-layer glass reactor produced by Shanghai Yuhua Instrument Co., Ltd., with a reactor capacity of 10L. The deproteinization treatment was carried out at a temperature of 80-110° C. with a 5% by weight NaOH aqueous solution, and the insoluble matter thus obtained was washed with water and dried.

[0069] (2) Add 3% by weight hydrochloric acid solution to t...

Embodiment 2

[0072] Example 2 : Preparation of paper-making tobacco sheet with low fiber content

[0073] Its papermaking method tobacco sheet preparation steps are as follows:

[0074] 1) 50g of crushed tobacco powder and 60g of tobacco stems were leached with water under the conditions of solid-liquid mass ratio of 1:7 and 1:9, temperature of 65°C and stirring rate of 200rpm respectively, filtered with gauze after leaching, and the filtrate After centrifugation, the supernatant was taken, and the crushed tobacco powder and the tobacco stem filter residue were repeatedly leached twice with water, and the water volume was half of the previous water volume; all the supernatants were combined, and the combined supernatant was concentrated to 110g. Obtain the coating solution 1 for tobacco sheet; the concentrated, for example, use the R-201 type rotary evaporator produced by Shanghai Shensheng Biotechnology Co., Ltd., and the SHB-III type circulating water type multi-purpose vacuum pump pro...

Embodiment 3

[0087] Example 3: Preparation of paper-making tobacco sheet with low fiber content

[0088] Its papermaking method tobacco sheet preparation steps are as follows:

[0089] Proceed in the same manner as in Example 2, except that the addition of the water-soluble biopolysaccharide of the present invention is increased to 1.5%, and the addition of wood pulp is reduced to 4%.

[0090] The smoking evaluation team is composed of 10 cigarette sensory evaluation experts, and uses the nine-degree scale method to compare the smoking of the original sheet and the new sheet with low fiber content. The results are shown in the following table:

Abstract

The invention relates to a water-soluble biological polysaccharide with low polymerization degree, a method for preparing papermaking tobacco sheets with low fiber content by using the polysaccharide and a product obtained by the method. The water-soluble biological polysaccharide with low polymerization degree is obtained by hydrochloric acid solution immersion of aspergillus niger or shrimp bran, protein removal treatment, calcium removal, decoloration, acetyl removal treatment, depolymerization and oxidative cutting. The papermaking tobacco sheets are prepared by substituting partial wood pulp fiber for the prepared water-soluble biological polysaccharide with low polymerization degree, and the novel papermaking tobacco sheets with low fiber content has better smoking quality besides the physical properties of the original products.

Description

【Technical field】 [0001] The invention belongs to the technical field of tobacco processing. More specifically, the present invention relates to a method for the preparation of paper-based tobacco sheets with low fiber content, and to the products obtained by said method. 【Background technique】 [0002] At present, the production of tobacco flakes is mainly based on papermaking flakes, because this method has better flexibility, filamentation rate and utilization rate than the rolling method and the thick pulp method. In addition, paper-making tobacco flakes also have the advantages of low density, high filling value, and good combustibility. However, in the traditional paper-making flake production process, in order to ensure that the flake has a basic skeleton structure, a large proportion wood pulp fibers, which will reduce the smoking quality of the sheet, such as increasing the irritation of the sheet, aggravating the prickly feeling and miscellaneous gas, etc., there...
