Problems solved by technology

However, the above-mentioned patents are all based on directly adding substances with coloring function in the production process, including a large amount of synthetic pigments and a small amount of natural pigments, which not only increases the production process, but also inevitably changes the coloring process due to the re-introduction of foreign substances. The taste of tobacco flakes makes it more difficult to adjust flavors

preparation example Construction

[0025] figure 1 A schematic flow chart showing the preparation method of the tobacco coating solution containing natural pigments of the present invention. Such as figure 1 Shown, the preparation method of this tobacco sheet coating liquid, comprises the steps:

[0026] Primary extraction step S1100: Extract 10-50 parts by weight of the raw material of the appearance improving agent with an extraction solvent to obtain an extract A;

[0027] Secondary extraction step S1200: Dilute the extraction solution A with the extraction solvent to form a diluted extraction solution A, and use the diluted extraction solution A to extract 60-120 parts by weight of tobacco fragments and / or tobacco stems to obtain an extraction solution B ;

[0028] Concentration treatment step S1400: Concentrate the extract B to a density of 1.0-1.5g / cm 3 ;

[0029] Wherein, in the primary extraction step S1100, it is preferable to pulverize the raw material of the appearance improving agent into a pow...

Embodiment 1

[0044] Weigh 50 kg of dried gardenia fruit and 600 kg of tobacco leaf fragments, crush the dried gardenia fruit to a powder with a particle size of less than 10 mm, and crush the tobacco leaf fragments to a powder with a particle size of less than 1.5 mm. Place the crushed dried gardenia fruit in 500kg of water, heat at 40°C, stir and extract for 3 hours, and obtain the extract A containing the appearance improving agent. Add 5000 kg of water to the above extract A to obtain 5400 kg of diluted extract A, put the crushed tobacco leaf fragments in the diluted extract A, heat at 60°C, and stir for 2 hours to obtain mixed extract B. Concentrate the above extract B in vacuum at 45°C until the density is 1.1g / cm 3 Left and right, the tobacco sheet coating liquid is obtained.

[0045] Based on the weight of the tobacco sheet coating liquid, the coating liquid is diluted with 1.4 times of water, and then saturately coated on the paper-making tobacco sheet by a rolling coating method....

Embodiment 2

[0047] Weigh 100 kg of dried gardenia fruit and 1200 kg of tobacco leaf fragments, crush the dried gardenia fruit to a powder with a particle size of less than 10 mm, and crush the tobacco leaf fragments to a powder with a particle size of less than 1.5 mm. Put the crushed dried gardenia fruit in 500kg of water, heat at 70°C, stir and extract for 0.5h, filter to obtain the extract A1 containing the appearance improving agent and dried gardenia pomace; add 500kg of water to the dried gardenia pomace, heat at 70°C , stirring and extracting for 0.5h, and filtering to obtain the extract A2 containing the appearance improving agent. The extracts A1 and A2 were mixed to obtain the extract A. Add 5200 kg of water to the above extract A to obtain 6000 kg of diluted extract A, put the pulverized tobacco leaf fragments into the diluted extract A, heat at 40°C, and stir for 2 hours to obtain mixed extract B. Concentrate the above extract B in vacuum at 45°C until the density is 1.1g / cm ...

Abstract

The invention discloses a method for preparing tobacco sheet coating liquid containing natural pigment. The method includes the following steps of (1) primary extraction, wherein 10-50 parts by weight, of appearance modifying agent raw materials are extracted through an extraction solvent to obtain extraction liquid A, (2) secondary extraction, wherein the extraction liquid A is diluted through the extraction solvent to form diluted extraction liquid A, and 60-120 parts, by weight, of tobacco debris and / or tobacco stems are extracted through the diluted extraction liquid A to obtain extraction liquid B and (3) concentration treatment, wherein the extraction liquid B is concentrated till the density ranges from 1.0 g / cm<3> to 1.5 g / cm <3> , and the appearance modifying agent is made of natural yellow pigment raw materials and / or natural red pigment raw materials. The invention further discloses tobacco sheet coating liquid prepared through the method. By means of the preparing method, the tobacco sheet coating liquid with the function of coloration can be produced, and thus plain yellow, lemon yellow and orange tobacco sheets can be produced.

Description

technical field [0001] The invention relates to the technical field of tobacco sheet processing, in particular to a method of mixing and extracting raw materials of an appearance improving agent with tobacco fragments or tobacco stems to improve the appearance of the tobacco sheet without changing the smell of the sheet. Background technique [0002] The production and processing technology of paper-making tobacco flakes (that is, artificial reconstituted tobacco leaves) is a paper-like reconstituted tobacco leaf technology formed by mixing tobacco chips or tobacco stems that have been extracted from the coating solution with wood pulp fibers and adhesives. With the increasing demand for low-tar cigarettes in the international and domestic cigarette markets, paper-making tobacco sheets are becoming more and more important in cigarette formulations. At the same time, with the continuous improvement of modern people's living standards, people's consumption demand is also gettin...
