Abstract:Flaxseed oil is rich in α-linolenic acid and linoleic acid，making it one of the most important plantderived sources of omega-3 polyunsaturated fatty acids，with high nutritional value and health benefits. However，its susceptibility to oxidation limited its practical applications. This paper reviewed recent research progress on the application of delivery systems in the stabilization of flaxseed oil，focusing on the nutritional value of flaxseed oil，its digestion and oxidation mechanisms，as well as the advantages and potential of emulsion systems，microcapsules，liposomes and hydrogel beads. It also highlighted the application prospects of various delivery systems in the encapsulation and stabilization of flaxseed oil，providing theoretical support and technical references for the design of functional flaxseed oil delivery systems and research on their stabilization protection.
