Conventional techniques of extracting oil using organic solvents pose health, safety, and environmental concerns. In modern extraction methods, green solvents such as water, ethanol, ethyl acetate, carbon dioxide, ionic liquids, and terpenes are currently gaining prominence. These green solvents present no signs of pollution and remain in liquid form over a temperature range of 0 to 140 °C. Other techniques covered in this review include microwave‐assisted enzymatic extraction, ultrasound‐assisted extraction, supercritical fluid technology, high pressure–assisted extraction, and pulse electric field–assisted extraction. These techniques are considered environmentally friendly because they exhibit less hazardous chemical synthesis, use renewable feedstock, and reduce the chemical load and emissions generated by organic solvents. Aqueous enzymatic extraction is a novel technique that uses enzymes as the medium for extraction of oil. Selection of the enzymes solely depends on the structure of the oilseed and the composition of the cell wall. Studies reveal an enzyme to substrate ratio of 1% to 8%, the temperature of 40 to 55 °C, and a pH of 4 to 8 to be typical for enzymatic extraction of oil from different oilseeds. Microwave‐assisted extraction has proven to impart significant effects on mass transfer and offers high throughput and extraction efficiency. A microwave power of 275 to 1,000 W and a temperature range of 30 to 60 °C are noticed in the different studies. The review presents a comprehensive account of the modern extraction techniques, the parameters responsible for yield and quality, and their industrial applications. Besides, the review highlights the optimized parameters for oil extraction from different oil‐bearing materials.

新型采油技术:工艺条件,质量参数和优化

使用有机溶剂提取油的常规技术带来了健康,安全和环境方面的问题。在现代提取方法中,绿色溶剂(例如水,乙醇,乙酸乙酯,二氧化碳,离子液体和萜烯)目前正日益受到关注。这些绿色溶剂没有污染迹象,并且在0至140°C的温度范围内保持液态。本文中涉及的其他技术包括微波辅助酶提取,超声辅助提取,超临界流体技术,高压辅助提取和脉冲电场辅助提取。这些技术被认为是环境友好的,因为它们具有较低的化学合成危险性,使用可再生原料,并减少了有机溶剂产生的化学负荷和排放。水性酶提取是一种使用酶作为提取油的介质的新技术。酶的选择仅取决于油料种子的结构和细胞壁的组成。研究表明,酶与底物的比例为1%至8%,温度为40至55°C,pH为4至8,这是从不同油料中酶法提取油的典型方法。事实证明,微波辅助萃取可对传质产生重大影响,并具有高通量和萃取效率。在不同的研究中发现微波功率为275至1,000 W,温度范围为30至60°C。该综述全面介绍了现代提取技术,负责产量和质量的参数及其工业应用。除了,
