Preparation method of endogenous oily humectant for tobaccos

Abstract

The invention discloses a preparation method of an endogenous oily humectant for tobaccos. The preparation method comprises the steps of adding a solvent into a tobacco raw material, extracting by heating, carrying out suction filtration, concentrating filtrate to form paste, settling the paste by using ethanol, regulating the acid value by using NaHCO3 and hydrochloric acid, desalting, and carrying out static microwave vacuum drying on a sediment to obtain crude polysaccharide; primarily purifying the crude polysaccharide, and dialyzing to remove small-molecular impurities after separating and purifying by sequentially using a DEAE-cellulose column, a SephadexG column and a Sephrose column to obtain pure tobacco endogenous polysaccharide; adding a solvent into the tobacco raw material to carry out cold extraction, carrying out suction filtration, concentrating filtrate until no solvent is separated out, adding a solvent to dissolve, carrying out suction filtration, and removing the solvent to obtain tobacco oil substances; and dissolving the pure tobacco endogenous polysaccharide by using a solvent to obtain a solution with the mass concentration of 50%, then, mixing the solution and the tobacco oil substances to 100 parts according to the mass part of (1-99):(1-99), homogenizing at high pressure, and uniformly mixing to obtain the endogenous oily humectant for tobaccos. After the humectant is added into cut tobaccos, the smoking quality of cigarettes can be ensured, and the moisture retention and moisture-proof effects are remarkable.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and relates to the preparation and application method of a humectant for cigarettes. Background technique [0002] The flavor-enhancing and moist-retaining technology of Chinese-style cigarette products is a widely concerned issue in the tobacco industry. Due to the characteristics of easy dehydration and hygroscopicity of shredded tobacco, domestic cigarette products are generally easy to dehydrate and dry under dry climate conditions, and easy to absorb moisture and become moldy under humid conditions. These characteristics are closely related to the physical and chemical structure of shredded tobacco. . Fluctuations in the moisture content of shredded tobacco can significantly affect the stability of the shredded shredded process and the changes in the chemical composition of smoke, thereby affecting the sensory comfort of cigarette products and the stability of product quality. ...

Chinese patent CN101658323 discloses a wax ester tobacco humectant and its preparation method. The tobacco humectant is mainly formed by emulsifying wax, emulsifier and water at high temperature. It is a kind of blocking tobacco humectant. Its function is to form a closed barrier on the surface of shredded tobacco to prevent the evaporation and loss of internal moisture. It also has two functions of moisturizing and moisture-proof. However, the tobacco humectant needs to be produced by high-temperature emulsification, and the emulsifier content used is high, and the smoking quality will be affected. influential

Chinese patent 201210292418.5 discloses a vegetable oil tobacco humectant and its preparation method. The humectant is mainly prepared from vegetable oil, a small amount of emulsifier and auxiliary agent. Since it is an exogenous additive, it will be inferior in compatibility. There is a certain influence
