利用微乳技术从植物油料中同步提取油脂及天然活性成分的研究进展

微乳液是不需外界能量推动,就能自发形成的一种呈透明状态、各向同性并且具有热力学稳定的分散体系。因为水相和混表面活性剂可以与植物油料中所含的油相构建形成稳定的、具有双亲性的微乳体系,所以可利用微乳技术从植物油料中同步提取出油脂与天然活性成分,且达到简易、高效、无毒无害的目的。本综述概述了微乳体系特性与形成理论,以及利用微乳技术同步提取出植物油料中所包含的油脂及天然活性成分的研究进展,为未来微乳技术在提取植物油料中的发展提供参考。

Advances in the simultaneous extraction of oils and natural active ingredients from vegetable oils by microemulsion technology

Microemulsion (ME) is a transparent, isotropic and thermodynamically stable dispersion that spontaneously forms without external energy. Because the aqueous phase and the mixed surfactant can be constructed with the oil phase contained in the vegetable oil to form a stable, amphiphilic microemulsion system, the microemulsion technology can be used to simultaneously extract the oil and the natural active ingredient from the vegetable oil. And achieve the purpose of simple, efficient, non-toxic and harmless. This review summarizes the characteristics and formation theory of microemulsion system, and the research progress of simultaneous extraction of oils and natural active ingredients contained in vegetable oils by microemulsion technology, which provides a direction for the future development of microemulsion technology in extracting vegetable oil.
