Abstract:

Chemical constitutions and its physical and chemical properties of capsaicinoids were described in this paper. 10 Methods for capsaicin's purification at home and abroad in recent years were also reviewed, which contained Sodium-hydroxide method, Ion exchange process, Solvent extraction, Supercritical carbon dioxide extraction (SFE), Enzymatic extraction, Ultrasonic extraction, Microwave extraction, Pressure-shear Induced Chemical Transitions (PICT), Biological method, Chemical synthesis. The different extracting methods were compares. Finally, a study of capsaicin application prospect was also presented.
