Research Progress on Embedding Flaxseed Oil in Emulsion System

Abstract

Flaxseed oil is rich in polyunsaturated fatty acids and has a variety of physiological functions, at the same time, flaxseed oil has poor oxidation stability, low water solubility and low bioavailability, which seriously limits its application in food and other fields. Embedding flaxseed oil in emulsion system is a potential approach to address these deficiencies. This paper summarizes the characteristics of different emulsion systems, such as ordinary emulsion, microemulsion, nanoemulsion, Pickering emulsion, multiple emulsion and gelled emulsion, as well as the research status of embedding flaxseed oil. Based on the reasons of oxidative stability and bioavailability, the application status of flaxseed oil after embedding in emulsion system is reviewed, aiming to provide some theoretical reference for the in-depth study of emulsion system and the wide application of flaxseed oil.
