Problems solved by technology

However, the various components contained in the tree moss extract have the characteristics of strong volatility. If it is directly used in tobacco, the aroma of cigarettes is easy to volatilize and lose during storage, and the aroma loss is serious, resulting in shortened cigarette life and insufficient aroma when smoking.

Abstract

The invention discloses a tree moss extract microcapsule and its preparation method. The tree moss concrete microcapsule is prepared by using chitosan and sodium carboxymethylcellulose as main components of a wall material, using tree moss extract as a main component of a core material, using tea polyphenol as a cross-linking agent and using surfactants Tween 80 and Span 80 as auxiliary materials. As chitosan and sodium carboxymethylcellulose respectively carry positive charge and negative charge in a specific pH environment, a capsule wall is formed through electrostatic force. And tea polyphenol is used as a cross-linking agent to solidify envelope. Thus, the prepared microcapsule has good stability, and the core material is not easy to leak. During tobacco combustion, the wall material of the microcapsule is damaged and the core material is released so as to have a fragrance-enhancing effect and achieve the purpose of improving cigarette quality. By addition of tea polyphenol, smoke injury can be reduced, and the tea polyphenol has a certain health-care function. The preparation method provided by the invention has characteristics as follows: the technology is simple; operation condition is mild; reagents used in the invention are environmentally-friendly; and the product is safe and nontoxic.

Description

technical field [0001] The invention belongs to the field of flavor and fragrance components and tobacco ingredients, and in particular relates to a tree moss extract microcapsule and a preparation method thereof. Background technique [0002] Tree moss extract is a paste-like substance extracted from spice plant tree moss by benzene or petroleum ether. It has a unique natural fragrance of liverwort plants and a strong resinous smell. It has a long-lasting fragrance and has a good fragrance-fixing effect. It plays an important role in the deployment of various flavors such as tobacco additives and daily cosmetics. The tree moss extract has been widely used in tobacco companies, and its use in cigarettes can enhance the fragrance and natural flavor, cover up the bad smell and earthy smell of tobacco, and improve the quality of cigarette smoke. However, the various components contained in the tree moss extract are highly volatile, and if it is directly used in tobacco, the ar...
