Problems solved by technology

On the one hand, this method will cause damage to the respiratory tract and eyes, and it is difficult to use it in large quantities. On the other hand, it will produce uncoordinated breath on the sensory quality of recombined tobacco leaves, so it is not suitable for popularization.
The recombined tobacco leaves produced by the above two methods will have various defects such as uneven coloring, poor solubility, brittle tobacco dry board, uncoordinated chemical indicators and smoke indicators, and serious pollution.
[0004] With the improvement of production technology, the comprehensive use performance of natural pigments has been higher than that of synthetic pigments, but the natural pigments of natural monomers are relatively rare, and most of the single natural pigments are raw material colorants, which are not suitable for adding directly to tobacco Coloring, which requires the use of various shades of natural pigments for debugging and compounding to achieve the desired effect
[0005] Currently, there are no natural color modifiers available on the market specifically for the coloration of reconstituted tobacco leaves

Embodiment 1

[0047] A color regulator specially used to change the appearance of recombined tobacco leaves, which contains the following substances in mass percentage: 10% natural β-carotene, 20% natural lycopene, 0.1% citric acid, 0.01% tannic acid, 0.15% soda ash, 0.2 % guar gum, 0.05% potassium acetate and 69.49% caramel, the natural β-carotene and natural lycopene are modified through the following supercritical extraction, membrane reverse osmosis technology separation and purification and emulsification embedding:

[0048] (1) Put the preliminarily processed tomatoes and carrots into the extraction kettle respectively, use a booster pump to increase the pressure to 14.7-16.2Mpa, and adjust the temperature to 35.5-41.5°C at the same time, and the carbon dioxide gas is condensed into a liquid through a heat exchanger. Use a booster pump to raise the pressure to the pressure required for the process (should be higher than the critical pressure of carbon dioxide), and at the same time adj...

Embodiment 2

[0053] A color regulator specially used to change the appearance of recombined tobacco leaves, which contains the following substances in mass percentage: 45% natural β-carotene, 35% natural lycopene, 0.5% citric acid, 0.2% tannic acid, 0.5% soda ash, 0.45% % guar gum, 1.0% potassium acetate and 17.35% caramel, the natural β-carotene and natural lycopene are through the same supercritical extraction as in Example 1, the reverse osmosis technology separation and purification of the membrane and the emulsification package Buried modified, the difference is that in the step (4), the following substances are compounded according to the following mass percentages: 45% natural β-carotene, 35% natural lycopene, 0.5% citric acid, 0.2% Tannic acid, 0.5% soda ash, 0.45% guar gum, 1.0% potassium acetate and 17.35% caramel are stirred and mixed evenly for deployment.

Embodiment 3

[0055] A color regulator specially used to change the appearance of recombined tobacco leaves, which contains the following substances in mass percentage: 30% natural β-carotene, 30% natural lycopene, 0.3% citric acid, 0.1% tannic acid, 0.5% soda ash, 0.3% % guar gum, 0.5% potassium acetate and 38.3% caramel, the natural β-carotene and natural lycopene are through the same supercritical extraction as in Example 1, the reverse osmosis technology separation and purification of the membrane and the emulsification package Buried modified, the difference is that in step (4), the following substances are compounded according to the following mass percentages: 30% natural β-carotene, 30% natural lycopene, 0.3% citric acid, 0.1% Tannic acid, 0.5% soda ash, 0.3% guar gum, 0.5% potassium acetate and 38.3% caramel are stirred and mixed evenly for deployment.

Abstract

The invention discloses a color regulator special for improving appearance of recombinant tobacco and a preparation method of the color regulator and belongs to the technical field of preparation of food colorants. The color regulator is prepared by mixing three natural pigments including beta-carotene, lycopene and caramel and five additive aids including guar gum, tannic acid, citric acid, sodaand methyl acetate according to a certain ratio, wherein the natural pigments are separated and purified by a supercritical CO2 extraction technology and a reverse osmosis technology; and oil-solublebeta-carotene and lycopene are modified into water-soluble pigments by an emulsification embedding technology. The preparation method is simple and easy to implement. The color regulator has the advantages of high water solubility, strong coloring power, stable performance and safety and no toxicity in combustion. High-quality recombinant tobacco can be prepared by the color regulator.

Description

technical field [0001] The invention relates to a pure natural food coloring, which belongs to the technical field of food coloring preparation, in particular to a color regulator specially used for improving the appearance of recombined tobacco leaves and a preparation method thereof. Background technique [0002] In the existing recombined tobacco leaf production technology, there are two main types of coloring methods. The first type is to utilize the ratio liquid of synthetic pigment to carry out coloring. Synthetic pigments are made from coal tar, and the country allows limited use, but a large number of research reports point out that almost all synthetic pigments cannot provide nutrients to the human body, and some synthetic pigments may even endanger human health. The former Soviet Union conducted long-term animal experiments on synthetic pigments from 1968 to 1970, and found that the carcinogenic rate was as high as 22%; researchers in the United States, Britain an...
