亚临界低温萃取技术装备和应用研究进展 Advance in equipment and application of subcritical low-temperature extraction technology

20世纪90年代初亚临界低温萃取油脂技术工业化装备诞生于中国，30年来已建成90多套科研装置和200多套工业化生产装备,因其具有投资小、生产成本低、规模化等优势，在天然产物脂溶性成分保质提取方面发挥了较好的作用。简述了亚临界低温萃取技术的历史与工业化装备的诞生、所用溶剂及性质、技术优势与食品安全性，综述了亚临界低温萃取工业化生产装备的发展历程、应用领域、发展创新，以期为油脂低温加工、实现饼粕高值化利用装备的选择提供参考。Subcritical low-temperature extraction oil technology industrial equipment was born in China in the early 1990s, more than 90 sets of scientific research equipment and more than 200 sets of industrial production equipment have been built in the past three decades. Because of its small investment, low production costs, scale and other advantages, it has played a better role in the preservation of natural products fat-soluble components extraction. The history of subcritical low-temperature extraction technology and the birth of industrial equipment, solvents and properties, technical advantages and food safety were briefly described, and the development process, application fields and innovative development of subcritical low-temperature extraction industrial production equipment were summarized, so as to provide reference for the selection of equipment for low-temperature oil processing and high-value utilization of cake and meal
