Problems solved by technology

An important factor affecting the final effect of microcapsules is the wall material used, especially the microcapsules used in tobacco. When the protein and lipid substances are burned, they usually have obvious odors, which seriously affect the smoking quality of cigarettes. Not suitable for the preparation of tobacco flavor and fragrance microcapsules;

Abstract

The invention relates to a microcapsule, which comprises a core material and a wall material, wherein the core material is tree moss absolute; the wall material is a konjac glucomannan and chistan compound. The microcapsule has the advantages that (1) because of the synergistic function of polysaccharides, the film-forming property is better after the konjac glucomannan and the chistan are compounded, and the core material can be well protected; (2) because the physical and chemical properties of the microcapsule are stable, when a cigarette is burnt, the wall material is damaged, the core material is released, the fragrance increasing function is realized, and the purpose of improving the quality of the cigarette is realized; (3) the technology of a preparation method is simple, the environment-friendly effect of a selected reagent is realized, and the obtained product is safe and poisonless.

Description

technical field [0001] The invention relates to the technical field of essence and fragrance microcapsules, in particular to a microcapsule used in cigarettes and a preparation method thereof. Background technique [0002] Treemoss Absolute is derived from the spice plant Treemoss, which has a unique natural fragrance of liverwort plants and a strong resinous smell, with a long-lasting fragrance and a good fragrance-fixing effect. In the prior art, it is often used in cigarettes to enhance the fragrance and natural flavor, cover up the bad smell and earthy smell of tobacco, and improve the quality of cigarette smoke; , resulting in shortened cigarette life, insufficient aroma when smoking, so that it cannot be directly used in cigarettes. [0003] Microcapsule technology uses natural or synthetic polymer materials (wall materials) to encapsulate solids, liquids or gases (core materials) in a tiny, semi-permeable or closed membrane using specific equipment and methods. Micr...
