Tangeretin is one of the most abundant polymethoxyflavones in citrus peel and its pharmacological effects are extremely rich. However, due to its poor solubility, bitter taste and poor oral bioavailability, the oral administration of tangeretin is still limited, which seriously limits its application in industrial production. The establishment of encapsulation and delivery systems to improve bioavailability is an effective method. This paper reviewed the research progress of the structure and properties, pharmacological effects and main methods to improve bioavailability of tangeretin, including emulsion delivery, lipid encapsulation, microencapsulation and other delivery and utilization research and application. The article aims to provide theoretical basis for the high-value application of tangeretin in functional food and pharmaceutical industry.
