| Abstract： | The supercritical fluid extraction(SFE) is a new technology which extracts and separates mix materials taking the supercritical fluid as the solvent, and uses high seepage ability and high dissolving capacity under this condition. The supercritical fluid technology does not cause pollution, has good selectivity and operates simply, so it has been used in medicine, food, environmental protection and chemical industry and demonstrates the broad application prospect. This paper introduced the characteristics of supercritical fluid, principles, fundamentals and technology of supercritical fluid extraction. Furthermore, the extraction of natural perfume and flavor material, natural pigment and each kind of natural chemical additive, zoology and botany fat, zoology and botany biological activity ingredient; separation of deleterious substance; analysis of pesticide residue and the research and application in food biology industry by SFE were also summarized. this paper is purposed to to provide people with reference and promote popularization and application of the supercritical fluid extraction technology in food industry. |
