Embodiment 1

[0059] In the process of paper-making tobacco flakes, tobacco stem extracts are used as the main raw material to biosynthesize natural pigments through microbial fermentation, and then the prepared natural pigments are added back to tobacco flakes to obtain tobacco flake products with enhanced color and flavor. Specifically include the following steps:

[0060] (1) Preparation of tobacco stem extract medium

[0061] Directly take the primary tobacco stem extract produced in the raw material extraction process of the papermaking tobacco sheet processing process. The primary tobacco stem extract is generally extracted at 60°C with 3 to 10 times the weight of water to extract the tobacco stem 5 ~30min to obtain, usually sent to the sewage treatment system as waste liquid for processing; in the present embodiment, 1% sucrose by weight, 0.8% NaH 2 PO 4 , natural pH, prepared tobacco stem extract culture medium, sterilized at 110°C for 20 minutes and then used for later use;

Embodiment 2

[0072] In the cut stem processing technology, the present invention uses tobacco stem extract as the main raw material, biosynthesizes natural pigment through microbial fermentation, and then adds the prepared natural pigment back into the cut stem to obtain a cut stem product with enhanced color and flavor. Specifically include the following steps:

[0073] (1) Preparation of tobacco stem extract medium

[0074] Take the tobacco stem extraction liquid produced in the raw material extraction process in the cut stem processing process. The tobacco stem extraction liquid is generally obtained by extracting the tobacco stems with 3 to 10 times the weight of water for 5 to 60 minutes at 40-80 ° C. Usually Treat as waste liquid; In the present embodiment, add the sucrose of 0.5% by weight, the NaH of 0.5% with tobacco stem extract 2 PO 4 , natural pH, to prepare the tobacco stem extract medium, which is sterilized for subsequent use;

Embodiment 3

[0085] In the tobacco threshing and redrying process, the tobacco stem extract is used as the main raw material, and the red yeast pigment is biosynthesized through microbial fermentation, and then the prepared red yeast pigment is added back to the tobacco sheet to obtain a color-enhancing and flavor-enhancing tobacco sheet. products, including the following steps:

[0086] (1) Preparation of tobacco stem extract medium

[0087] Take the tobacco stems produced in the process of tobacco threshing and re-baking, add 10 times the weight of water, and extract at 30°C for 12 hours to fully dissolve the soluble matter; then separate the solid and liquid to obtain the tobacco stem extract and solid-phase stem Slag; add 1% by weight soluble starch, 0.3% NaH to the extract 2 PO 4 , the tobacco stem extract medium was obtained, and it was sterilized at 100°C for 30 minutes for later use; the solid-phase stem residue was used for fermentation to produce peat;

Abstract

The invention provides a biological coloring and flavoring method for tobacco products. In the tobacco processing procedure, tobacco or tobacco extract liquid is used as a main raw material, the main raw material undergoes microbial fermentation to biosynthesize natural pigment, and the natural pigment is added back to the tobacco products to obtain colored and flavored tobacco products. The method includes the steps of tobacco extract liquid culture medium preparation, fermentation seed liquid preparation, natural pigment synthesis, pigment extraction and back adding of the pigment to the tobacco products. The method is suitable for coloring and flavoring of the tobacco products in the technology of flavoring of tobacco sheets, cut stems, flue-cured tobacco laminas and cigarettes. According to the method, tobacco waste is converted into the natural pigment in a biological mode, the natural pigment is used as a coloring adjunct to be used in the tobacco products and replaces chemical pigment, color and flavor are enhanced at the same time, and the two purposes are achieved; on-line digestion and utilization of the tobacco waste and liquid waste can be achieved, pollutant discharge is reduced, and good social benefits, environment benefits and economic benefits are generated.

Description

technical field [0001] The invention relates to the fields of tobacco processing and resource utilization of tobacco waste, in particular to a method for biologically enhancing color and aroma of tobacco products. Background technique [0002] The appearance color of tobacco products is one of the important aspects of tobacco quality. Golden and orange tones are the appearance characteristics of high-quality tobacco. Therefore, maintaining and improving the appearance color of tobacco during tobacco processing and highlighting golden and orange tones are the processing technology must pay attention to quality standards. During the processing of tobacco flakes, shredded stems, tobacco leaves, and shredded tobacco, food coloring is usually added to improve the appearance and luster of tobacco products. However, at present, the food colorings added in tobacco processing are often chemically synthesized pigments. Because the molecular structure and properties of chemically synt...
