Study on the pyrolysis characteristics of cyclodextrin coated flavor

Abstract: As a kind of important and direct means, the flavor coating technology has been developed in the field of domestic and foreign related fields in recent years. In recent years, the research work on the modification of β-Cyclodextrin has been paid more attention, and has made a breakthrough. Believe that with the further promotion of β-Cyclodextrin and its derivatives, they will become a new type of raw materials service Yu Guomin economic construction. This paper focuses on the study on pyrolysis characteristics of the product with β-Cyclodextrin as the wall material, coating flavor formation of mainly includes for β-Cyclodextrin coated essence of process optimization, and the product of thermal gravimetric analysis and infrared analysis to product qualitative properties. In this paper, the optimum processing scheme and the physical and chemical data analysis of β-Cyclodextrin inclusion compound were determined by measuring the embedding rate of β-Cyclodextrin in the condition of different temperature and reaction time.

Key words：β-Cyclodextrin；Coated；Process optimization；Thermogravimetry。
