Description

Technical Field

[0001] The invention belongs to the technical field of tobacco modified raw materials and additives, and particularly relates to a tobacco moisturizing agent and application thereof. Background Art

[0002] Tobacco is a smokeable consumer product, and its standards are similar to those of food. Due to various factors such as my country's vast territory and complex and diverse climate, most domestic cigarettes are prone to moisture loss and weakened flavor after being stored for a period of time, greatly reducing consumers' experience and comfort. The importance of tobacco moisture retention technology research has been widely recognized by the academic community. Improving the moisture retention performance of tobacco can not only improve the sensory comfort of cigarettes, but also improve its competitiveness in the tobacco market.

[0003] Today, the most common means of improving the moisturizing properties of tobacco is to add humectants to tobacco. Humectants are usually chemicals added to tobacco to keep the tobacco moist and improve its taste. These humectants can be natural, such as glycerol or propylene glycol, or synthetic compounds, such as polyethylene glycol. The selection of suitable humectants requires consideration of their impact on tobacco quality and health effects, as well as availability and cost during the production process. The main purpose of humectants is to stabilize the moisture content of tobacco during processing. At the same time, humectants also have an important impact on the quality of cigarettes and cigarette rods. Humectants play an important role in stabilizing the moisture content of tobacco leaves and improving the comfort of smoking cigarettes under different climatic conditions, especially under low humidity climatic conditions. It can significantly increase the equilibrium moisture content and reduce the dryness and irritation of cigarettes.

[0004] The existing humectants have the problem of insufficient moisture retention in low humidity environments, resulting in a strong dry and pricking sensation when smoking cigarettes, which affects smoking. However, polyhydroxy alcohol humectants have poor moisture-proof effects in high humidity environments. After absorbing moisture, moisture is transferred to the cigarette paper, increasing the possibility of yellow spot defects on the surface of cigarettes, which not only affects the appearance quality of the cigarettes, but also affects the sensory quality of cigarettes. Humectants such as glycerin and propylene glycol have good moisture retention and absorption capabilities in low humidity environments, but in high humidity environments, more moisture is absorbed, resulting in a decrease in the moisture-proof ability of tobacco leaves. At the same time, propylene glycol produces acetaldehyde and acetone during cigarette smoking, which increases the content of harmful substances in the smoke. Summary of the invention

[0005] The purpose of the present invention is to provide a tobacco moisturizer and application, which can simultaneously improve the physical moisturization and sensory moisturization of tobacco and improve the smoking quality, so as to solve the problems existing in the above-mentioned background technology.

[0006] To achieve the above objectives, this application is implemented through the following technical solutions:

[0007] A tobacco humectant, which is glyceride.

[0008] Furthermore, the glyceride is one or more of monoacetin, diacetin or tripropionin. If there are two glycerides, the weight ratio of monoacetin to diacetin is 1-3:1, the weight ratio of monoacetin to tripropionin is 1-3:1, the weight ratio of diacetin to tripropionin is 2:3, and if there are three types of monoacetin, diacetin and tripropionin, the weight ratio of monoacetin, diacetin and tripropionin is 3:1:2.

[0009] An application, using any of the above tobacco humectants on tobacco leaves.

[0010] Furthermore, the tobacco leaves are tobacco leaves without added spices, and the tobacco stems are removed.

[0011] Further, the application method adopts the following steps:

[0012] S1. Weigh a set weight of tobacco humectant and dissolve it in a solvent to obtain a tobacco humectant solution;

[0013] S2, spraying the tobacco humectant solution evenly on tobacco leaves of a set weight;

[0014] S3. Place the tobacco leaves sprayed with tobacco moisturizer in a constant temperature and humidity chamber for 48 hours to balance the moisture.

[0015] Furthermore, the solvent is deionized water.

[0016] Furthermore, the amount of humectant added is 0.5-3% of the weight of the tobacco leaves.

[0017] The beneficial effects of the present invention are:

[0018] 1. The tobacco humectant of the present invention can maintain physical humectancy and sensory humectancy at the same time without affecting the smoking quality of the cigarette.

[0019] 2. The method for improving the moistness of tobacco of the present invention is easy to operate, has high working efficiency, and saves the working cost of moisturizing.

[0020] 3. The present invention discloses a new use of glyceride for physical and sensory moisturizing of tobacco, providing a new path for improving the moisturizing feel of tobacco. BRIEF DESCRIPTION OF THE DRAWINGS
