中文摘要:

      超临界二氧化碳萃取技术作为一种独特、清洁、高效、节能的分离方法, 可以解决传统提取技术中存在的诸多缺陷, 如使用有毒的有机试剂、高能源的使用以及低萃取得率等, 因此在食品加工中有较好的应用前景。油脂作为人体的3大营养素之一, 在维持人体正常生理机能的同时, 也具有诸多有益的生理功能, 对改善人体健康、预防疾病具有重要价值。因此本文聚焦超临界二氧化碳萃取技术, 系统地总结了超临界二氧化碳萃取的概念、作用机制、工艺流程及特点和影响因素, 以及近几年在如小麦胚芽油、米糠油、大豆胚芽油等植物油脂和鱼油、昆虫油等动物油脂方面应用的研究现状, 旨在为超临界二氧化碳萃取技术在科学研究和食品加工应用提供一定的理论参考。

英文摘要:

      Supercritical carbon dioxide extraction technology, as a unique, clean, efficient, and energy-saving separation method, can solve many defects in traditional extraction techniques such as the use of toxic organic reagents, high energy consumption, and low extraction yield. Therefore, it has good application prospects in food processing. As one of the 3 kinds of major nutrients of human body, oil not only maintains the normal physiological function of human body, but also has many beneficial physiological functions, which is of great value to improve human health and prevent diseases. Therefore, this article focused on supercritical carbon dioxide extraction technology, systematically summarized supercritical carbon dioxide extraction’s concept, mechanism, process flow, characteristics and influencing factors, as well as the research status in recent years regarding its application in plant oils such as wheat germ oil, rice bran oil, and soybean germ oil, as well as animal fats like fish oil and insect oil, aimed to provide a theoretical reference for the scientific research and food processing applications of supercritical carbon dioxide extraction technology.
