摘　　要：目前,植物油脂大多采用己烷溶剂浸出法,或预榨-己烷溶剂浸出法制取;然而,从安全及环境方面而言,人们对替代己烷浸出法技术日益寄予更多期待。完全压榨法和超临界二氧化碳流体浸出法已在小规模生产中得以利用,异丙醇浸出、酶法浸出研究也在进展之中;但这些替代技术在大豆油、菜籽油等一般油脂大量生产中仍尚未实用化,为此,有必要进一步研究提高收率,降低生产成本。Currently, a majority of vegetable oil extracted from various oil-bearing materials by either hexane extraction or a process that combines pressing and hexane extraction. In terms of the safety and environmental issues. An expectation for developing an alternative process of hexane extraction gets bigger as time goes by. Full pressing and supercritical carbondioxide extraction have alreadybeen applied for a small scale production, isopropyl alcohol extraction, enzymatic aqueous extraction is also investigated. But these alternative processes are not relevant for alarge scale production of commodity oils, such as soybean, Canola and so on. Further studies to increase oil yield and reduce operational cost are required.
