Citrus is the largest fruit in the world and in China,and its fruits are rich in flavonoids.Citrus flavonoids possess various beneficial biological activities,including antioxidant,anti-inflammatory,lipid-lowering,anticancer,bacte-riostatic,and neuroprotective properties,which contribute to human health.However,citrus flavonoids face challenges such as poor solubility,stability,and low bioavailability,which restrict their application in industrial production.The development of a stable encapsulation has emerged as an effective approach to overcome these limitations.This paper aims to provide a comprehensive review of the research progress regarding the structure,types,and main encapsulation methods for citrus flavonoids,which have been investigated and will be analyzed in terms of their advantages and disad-vantages.The effects of citrus flavonoids encapsulation on physiological activities will be summed up.Additionally,the effects and application of encapsulation on the main citrus flavonoids(naringin,hesperidin,neohesperidin,etc)will be summarized.The findings are expected to provide theoretical basis for the high-value utilization of citrus flavonoids in functional food,cosmetics,pharmaceuticals,and other related industries.
