Problems solved by technology

Since the types and contents of endogenous enzymes in flue-cured tobacco are relatively small, the tobacco leaves cannot be fully alcoholized in a short period of time, so the purification period is long, the warehouse area and human resources are more occupied, and the additives extracted from fresh tobacco leaves contain a large amount of endogenous enzymes. Source enzymes, treat tobacco leaves to promote the alcoholization process of flue-cured tobacco, in order to further improve the quality of tobacco leaves

Embodiment 1

[0052] A method for preparing a tobacco additive derived from fresh tobacco leaves includes the following steps:

[0053] Pick the mature middle tobacco leaves, wash the surface of the tobacco leaves and remove the main veins of the tobacco leaves, and then mix the tobacco leaves from which the main veins have been removed with a phosphate buffer solution at a temperature of 6°C in a mass-volume ratio of 1:8 to obtain a mixture; the phosphoric acid The pH of the buffer is 7, and the concentration is 0.03M;

[0054] Afterwards, the mixture is crushed by a crusher at 6°C until the diameter of the crushed residue is less than 2mm;

[0055] The crushed mixture is filtered through 5 layers of sterile gauze and the residue is discarded. The filtrate is filtered and concentrated with a 0.22um hollow fiber column, and concentrated to 18% of the original volume;

[0056] Then the concentrate is naturally settled at 3°C ​​for more than 10 hours until it is divided into 3 layers. The middle laye...

[0060] A method for preparing a tobacco additive derived from fresh tobacco leaves includes the following steps:

[0061] Pick the mature middle tobacco leaves, wash the surface of the tobacco leaves and remove the main veins of the tobacco leaves, and then mix the tobacco leaves with the main veins removed with a phosphate buffer solution at a temperature of 10°C in a mass-volume ratio of 1:8 to obtain a mixture; the phosphoric acid The pH of the buffer is 7, and the concentration is 0.05M;

[0062] Afterwards, the mixture is crushed by a crusher at 10°C until the diameter of the crushed residue is less than 2mm;

[0063] The crushed mixture is filtered through 5 layers of sterile gauze and the residue is discarded. The filtrate is filtered and concentrated with a 0.22um hollow fiber column, and concentrated to 22% of the original volume;

[0064] Then the concentrate is naturally settled at 8°C for more than 8 hours until it is divided into 3 layers. The middle layer material and th...

[0068] A method for preparing a tobacco additive derived from fresh tobacco leaves includes the following steps:

[0069] Pick the mature middle tobacco leaves, wash the surface of the tobacco leaves and remove the main veins of the tobacco leaves, and then mix the tobacco leaves with the main veins removed with a phosphate buffer solution at a temperature of 4°C in a mass-volume ratio of 1:12 to obtain a mixture; the phosphoric acid The pH of the buffer is 7, and the concentration is 0.01M;

[0070] Afterwards, the mixture is crushed by a crusher at 4°C until the diameter of the crushed residue is less than 2mm;

[0071] The crushed mixture is filtered through sterile gauze and the residue is discarded. The filtrate is filtered and concentrated with a 0.22um hollow fiber column, and concentrated to 20% of the original volume;

[0072] Then the concentrate is naturally settled at 4°C for more than 5 hours, and then it is divided into three layers by natural settlement. The middle laye...

Abstract

The invention relates to a tobacco additive prepared from fresh tobacco leaves as well as a preparation method and application of the tobacco additive, and belongs to the technical field of cigarette essence and spices. The method comprises the following steps: picking ripe middle tobacco leaves; washing the surfaces of the tobacco leaves and then removing main veins of the tobacco leaves; mixing the tobacco leaves with a phosphate buffer solution at the mass-volume ratio of 1 to 12; crushing an obtained biological mixture at 4 to 10 DEG C through a crusher; filtering the crushed mixture through a sterile gauze and removing filtered residues; filtering and concentrating filtrate with a hollow fiber column with the size of 0.22 micron; naturally depositing a concentrate at 4 DEG C to form three layers; uniformly mixing a middle-layer substance and a lowest-layer substance at the mass ratio of (2:1) to (1:2) to obtain the product. The preparation method is simple and the prepared additive is safe and pollution-free; any chemical substance, which is harmful to human bodies, does not need to be added; the additive does not weaken the fragrance when the content of tar of cigarettes is reduced, and is easy to popularize and apply.

Description

Technical field [0001] The invention belongs to the technical field of cigarette flavors and fragrances, and in particular relates to a tobacco additive derived from fresh tobacco leaves and a preparation method and application thereof. Background technique [0002] China is a big country in the tobacco industry, with its tobacco planting area and output ranking first in the world, and sales volume ranking first in the world. Tobacco planting and production play an important role in the national economy. Everyone knows that tar and other substances in tobacco are harmful to human health, but smoking has become a part of people's lives and it is difficult to change. At the same time, with the need of economic development, people have begun to accept smoking and shifted their focus to research on how to reduce tar and harm. It is not difficult to reduce the tar content. However, the large amount of flavor substances contained in tobacco reduces the tar while also greatly reducing i...
