Preparation method of chitosan/agarose xerogel particles and application of chitosan/agarose xerogel particles in cigarette filter tip

Abstract

The invention provides a preparation method of chitosan / agarose xerogel particles and an application of the chitosan / agarose xerogel particles in a cigarette filter tip. The preparation method comprises the following steps: adding chitosan and agarose to a citric acid solution, conducting heating and stirring so as to obtain a clear solution, and cooling the clear solution to room temperature, so that a transparent hydrogel is obtained; and freeze-drying the transparent hydrogel so as to obtain a xerogel, conducting mechanical crushing and screening so as to obtain xerogel powder, conducting uniform mixing and implementing a high-speed stirring granulating method so as to obtain chitosan xerogel particles, drying the chitosan xerogel particles at constant temperature and sieving the particles so as to obtain target particle samples which are 20-40 meshes. A composite filter tip, which is added with the particles, can effectively improve a moisture content in smoke; and meanwhile, smoking quality of cigarette can be enhanced. In addition, the method is simple and easy to implement and is applicable to large-scale industrial production.

Description

technical field [0001] The invention belongs to the field of moisture-retaining materials for cigarette filters, in particular to the preparation of chitosan / agarose xerogel particles and their application in cigarette filters. Background technique [0002] With the development of the national economy, consumers and the market have higher and higher requirements for the quality of cigarettes, especially the quality of smoking. As the core competitiveness of Chinese-style cigarettes, the research and development of cigarette moisture retention technology has been highly concerned by the cigarette industry. But the traditional moisture retention technology has become more and more difficult to meet the requirements of improving the smoking quality of cigarettes. Improving the moisture retention performance of cigarettes, that is, the moisture content in the smoke during smoking can effectively improve the smoking taste and quality of cigarettes, thereby enhancing the core com...
