摘　　要：超临界CO2脂肪酶酯交换反应是一种新型、绿色、高效的方法,在富集浓缩DHA、EPA等多不饱和脂肪酸方面具有很好的发展前景。本文对目前多不饱和脂肪酸的生产现状、传统酶法及以超临界CO2流体为介质的非水相脂肪酶法在多不饱和脂肪酸方面的应用进行综述,通过对比传统工艺并结合国内外最新研究进展,探讨超临界CO2脂肪酶酯交换反应在分离富集不饱和脂肪酸中的优势与应用前景,为相关研究提供依据。Supercritical CO2 lipase transesterification is a new, green and efficient method, which has a good development prospect in the enrichment and enrichment of DHA, EPA and other polyunsaturated fatty acids. In this paper, the current production status of polyunsatu-rated fatty acids and the application of traditional enzyme and non-aqueous lipase method using supercritical CO2 fluid as medium in polyunsaturated fatty acids were reviewed. By comparing the traditional separation process and combining with the latest research progress at home and abroad, to explore the advantages and application prospects of supercritical CO2 lipase transesterification in separation and enrichment of unsaturated fatty acids, and to provide basis for related research.
