[0032] The preparation method of the heated cigarette tobacco sheet of the present disclosure comprises the following steps:

[0033] Step (1): Prepare a medium containing glucose, peptone, yeast powder and citric acid monohydrate, inoculate Gluconacetobacter sp. ZT-01 with the preservation number CGMCC NO.21544, and culture it for a period of time with constant temperature and shaking , to obtain the seed solution.

[0034] The Gluconacetobacter sp. ZT-01 used in this disclosure is now preserved in the General Microbiology Center (CGMCC) of the China Microbiological Culture Collection Management Committee (CGMCC), the preservation number is CGMCC NO.21544, and the strain name is Gluconic Acid Acetobacter, the strain number is ZT-01, the classification is named Gluconacetobacter sp., the preservation time is December 23, 2020, and the preservation address is No. 3, No. 1, Beichen West Road, Chaoyang District, Beijing. The nicotine concentration that the gluconacetobacter ZT-0...

Embodiment 1

[0059] Pick a single colony of Gluconacetoacetobacter ZT-01 from the slope and inoculate it into 50mL medium (20g / L glucose, 5g / L peptone, 5g / L yeast powder, 1g / L citric acid monohydrate). Constant temperature shaking culture at 30°C for 48 hours to obtain seed solution;

[0060] Dilute the tobacco sheet concentrate with water to 10% mass fraction, and sterilize at 121°C for 15 minutes to obtain a tobacco culture medium;

[0061] The seed liquid is inoculated into the tobacco medium according to the weight ratio of 6%, and the inoculated solution is poured into 75cm 2 In the cell tissue culture bottle, the liquid level height is 2mm, and the culture is kept at a constant temperature for 5 days to grow into a bacterial cellulose film;

[0062] Add (dry weight content) 30% glycerol, 2% spices (tobacco extract: blueberry extract: the mass ratio of phenylethyl alcohol is 7:2:1) to the smoke powder with a particle diameter of 50 μm and mix evenly to obtain smoke powder;

Abstract

The invention discloses a preparation method of a heated cigarette tobacco sheet, which comprises the following steps: preparing a culture medium, inoculating gluconacetobacter ZT-01 with the preservation number of CGMCC NO.21544, and carrying out constant-temperature shake culture to obtain a seed solution; diluting the reconstituted tobacco concentrated solution, and sterilizing to obtain a tobacco culture medium; inoculating the seed solution into a tobacco culture medium according to a mass ratio of (6-15): 100, and culturing to obtain a bacterial cellulose membrane; preparing tobacco slurry according to the mass ratio of the tobacco culture medium to the tobacco powder material of (3-10): 1, and inoculating the seed solution into the tobacco slurry according to the mass ratio of (6-15): 100; flatly laying the inoculated tobacco pulp on a bacterial cellulose membrane at the height of 2-4 mm, and obtaining the heated cigarette tobacco sheet through constant-temperature standing culture. According to the preparation method of the heated cigarette tobacco sheet, the tobacco aroma can be improved and offensive odor can be reduced without adding wood fibers and adhesives, and the bacterial cellulose can be tightly captured on the tobacco sheet, so that the tobacco sheet has high smoke amount and good sensory quality.

Description

technical field [0001] The invention relates to the field of reconstituted tobacco leaves, in particular to a method for preparing heated cigarette tobacco sheet. Background technique [0002] Tobacco flakes, also known as reconstituted tobacco leaves, are an important form of tobacco waste reuse and have great environmental and economic value. Depending on the type, tobacco flakes can be added to traditional cigarettes or used in heat-not-burn cigarettes. There are three main production techniques: rolling method, thick pulp method and papermaking method. Among them, the reconstituted tobacco leaves produced by the thick pulp method and the rolling method have low elongation and low tensile strength, and are easily broken and broken when shredded or gathered. However, the papermaking method has a low effective load dry matter content due to the influence of the spread rate. [0003] Bacterial cellulose (BC) is a reticular natural nanocellulose produced by some microorgani...
