Embodiment 1

[0017] Prepare 1 L of 0.5% sodium alginate and polyethylene glycol solution, the molecular weight of polyethylene glycol is 400kDa, and the weight ratio of sodium alginate to polyethylene glycol is 1:10. Stir to mix evenly and remove air bubbles, place in a container connected to the outer tube of the concentric discharge port, and set aside. Dissolve 5.6g of menthol in 100 mL of glycerin, place it in a container connected to the inner tube of the concentric outlet, and squeeze the menthol solution and the polymer solution from the inner and outer tubes of the outlet at the same time to form a concentric Linear fluid, while rotating blades at 100 rpm to cut concentric linear fluid into fine particles, and solidify in 20% calcium chloride solution, after drying, menthol flavor microcapsules are obtained. The particle diameter of the obtained microcapsule is 1 mm, the thickness of the capsule material is 50 microns, and the menthol content is 10%.

Abstract

The invention discloses a temperature-sensitive micro capsule as well as a preparation method and application of the temperature-sensitive micro capsule. The temperature-sensitive essence micro capsule consists of essence for cigarette as core materials and high-molecular materials as capsule materials, wherein the high-molecular materials consist of sodium alginate and polyethylene glycol. The preparation method comprises the following preparation steps that water solution of the sodium alginate and the polyethylene glycol is prepared, the stirring is carried out so that the uniform dispersion is realized, and air bubbles are removed; the prepared solution of essence for cigarette is extruded out from an inner pipe of a concentric material outlet, meanwhile, the water solution is extruded out from an outer pipe of the concentric material outlet, concentric linear fluid is cut through a rotary blade, fine particles are formed, and curing and drying are carried out in calcium ion salt solution. The temperature-sensitive micro capsule has the beneficial effects that the temperature-sensitive micro capsule has the advantages that the prepared essence for cigarette can be sealed in the capsule, and the essence is not released at the room temperature, so the essence can be stored for a long time without invalidation. The temperature-sensitive micro capsule has the advantages that the resources of used raw materials are wide, the price is low, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to an essence microcapsule, and also relates to a preparation method and application of the essence microcapsule. technical background [0002] Flavor and fragrance technology is one of the core technologies of the cigarette industry. Adding flavors and fragrances to cigarettes can coordinate the aroma of cigarettes, improve the taste of smoking, and increase the sensory acceptance of cigarettes. The commonly used way of adding flavor to cigarettes at present is to add flavors and fragrances in shredded tobacco. However, since flavors and fragrances are highly volatile and lost, this leads to short shelf life and changes in smoking flavor of cigarette products. To this end, researchers have adopted a variety of ways to improve. One way is to add low-volatility flavoring substances to cigarettes. U.S. Patent No. 3312226 uses esterification to synthesize menthol lat...
