Fragrance and Flavor Microencapsulation Technology

Abstract

Fragrance and flavor are valuable ingredients in toiletries, cosmetics and foods. They play a very important role in these products. However, fragrances and flavors are complex mixtures of comparatively volatile substances and labile components of which the sensory perception can be changed as a result of heating, oxidation, chemical interactions or volatilization. Microencapsulation technology is an effective method to minimize the harm of these problems. Encapsulation of fragrances or flavors has been attempted using various methods. In this paper, the chemical and engineering processes for encapsulation of fragrance and flavor are discussed. The different coating materials and their application are depicted.
