中文摘要:

      油莎豆油是一种富含单不饱和脂肪酸、蛋白质等多种营养物质的优质食用油。本文对油莎豆油主要提取技术(超临界CO2萃取法、亚临界流体萃取法、压榨法、浸出法、水酶法、水代法、超声波辅助法和微波辅助萃取法)的近年研究进行了综述, 通过总结分析不同提取技术在实际操作中的特点和对油莎豆油基本理化性质、脂肪酸、甾醇、维生素E和挥发性化合物的影响, 建议未来油莎豆油发展可集中在优化传统榨油技术(压榨法、水代法和浸出法)的关键机械设备来提升油脂品质和降低新型榨油技术(水酶法、超临界CO2萃取法、超声波萃取法、亚临界萃取法、微波辅助萃取法)的生产成本来增加推广可行性、加强对高油酸油莎豆新品种的培育和加大油莎豆油功能研发力度3个方面, 以期为油莎豆油的产业化可持续发展提供理论支撑。

英文摘要:

      Cyperue esculentust L. oil was a kind of high-quality edible oil rich in monounsaturated fatty acids, protein and other nutrients. This paper reviewed the main extraction technologies of Cyperue esculentust L. oil (supercritical CO2 extraction, subcritical butane extraction, pressing, leaching, aqueous enzymatic extraction, aqueous extraction, ultrasonic-assisted extraction and microwave-assisted extraction) in recent years. By summarizing and analyzing the characteristics of different extraction technologies in practical operation and their effects on the basic physical and chemical properties, fatty acids, sterols, vitamin E and volatile compounds of Cyperue esculentust L. oil, it was suggested that the development of Cyperue esculentust L. oil in the future could focus on 3 aspects: Optimizing the key machinery and equipment of traditional oil extraction technologies (pressing, aqueous extration and leaching) to improve the quality of oil and reducing the production cost of new oil extraction technologies (aqueous enzymatic extraction, supercritical CO2 extraction, ultrasonic-assisted extraction, subcritical butane extraction and microwave-assisted extraction) to increase the popularization feasibility, strengthening the cultivation of new varieties of Cyperue esculentust L. oil with high oleic acid and increasing the research and development of its functions, so as to be beneficial to the industrialization of Cyperue esculentust L. oil.
