Abstract

The invention discloses a slowly-released filter stick essence microcapsule and a preparation method thereof. The slowly-released filter stick essence microcapsule is prepared from the following raw materials in parts by weight: 12-18 parts of sodium alginate, 6-12 parts of Arabic gum, 15-25 parts of emulsifier and 10-15 parts of filter stick essence. The preparation method comprises the following steps: firstly, respectively preparing an Arabic gum solution and a sodium alginate solution; then, injecting the sodium alginate solution into the Arabic gum solution proportionally to obtain a mixed wall material solution; in the stirring process, successively adding the emulsifier and the filter stick essence to obtain emulsion; standing; and carrying out high-voltage electrostatic treatment after foam is eliminated to obtain the microcapsule. The slowly-released filter stick essence microcapsule prepared by the invention has the advantages that the embedding rate is more than 80%, the particle diameter uniformity is good, the essence retention rate is more than 85% after the microcapsule is stored for 6 months at 20 DEG C, and the release rate of the essence microcapsule at 40 DEG C is about 6 times of the release rate of the essence microcapsule at 20 DEG C.

Description

technical field [0001] The invention relates to a slow-release filter stick essence microcapsule and a preparation method thereof, belonging to the technical field of tobacco. Background technique [0002] Adding essence to the filter rod is a new cigarette flavoring method. Compared with adding essence to shredded tobacco, it can not only cover up the pungent taste produced during the burning process of tobacco, but also prevent the generation of peculiar smell of essence under high temperature conditions and maintain the aroma of cigarettes. pure. However, the volatility of filter stick essence is extremely high, and the volatilities of various volatile components vary greatly. The volatilization of components not only causes the loss of essence, but also has a short fragrance retention period, and easily distorts the fragrance type of essence. Immobilizing or microencapsulating the fragrance is a better way to solve the problem. [0003] The paper "Application of Microe...
