Abstract

Flavors and fragrances in special active materials are applied widely in daily life, which can bring pleasant olfactory and gustatory sensations. However, their many ingredients are chemically unstable and susceptible to deterioration and loss when the flavor and fragrance are exposed to oxygen, light and heat. Nano and micrometer size capsules with a hollow core domain and a shell can effectively protect the stability of the flavor and fragrance and control their release. The structures and properties of flavor and fragrance capsules can be interestingly tailored by choosing a variety of shell materials. In this review, we give a brief overview with regard to the different preparation methods of flavor and fragrance capsules based on the type of wall material, including polymeric, inorganic and polymeric–inorganic materials. Besides, the application of flavor and fragrance capsules in food, tobacco, care products, textiles, leather and paper is briefly summarized. Moreover, the development trends of flavor and fragrance capsules are prospected.
