Synthesis of Mint-flavor Microcapsules and Its Application in Cigarettes

Abstract

By using microcapsule technology, the components that may react with each other can be made into microcapsule products respectively, so that they can be stabilized in a system, and each effective component can be released in an orderly manner and act at the corresponding time, thus improving the flavor and nutrition of the products. In order to further find an efficient and reasonable cigarette flavoring process, this study used gelatin and Arabic gum as composite wall materials to synthesize mint-flavored microcapsules by complex coacervation. Firstly, gelatin-Arabic gum dispersed peppermint oil in water medium to form micro-droplets, then the pH value of the system was adjusted, the solubility was reduced and condensed into capsules, and then glutaraldehyde was added for curing reaction. The test results show that the embedding efficiency of microcapsules is the highest when the mass ratio of mint essence to two sustained-release materials is 1:9. When the dosage of mint-flavor microcapsules is 10 ~ 15 mg/ cigarette, the aroma of cigarettes increases obviously, the irritation decreases, and the aroma of wild mint essential oil can also be coordinated with the cigarette aroma. The results show that the samples of mint-flavor microcapsules synthesized in this study greatly improve the aroma characteristics and smoking characteristics of cigarettes, which lays a foundation for the brand development of cigarettes and has a good application prospect.
