Background: Curcumin (Cur) is a natural pigment containing a diketone structure, which has attracted extensive attention due to its strong functional activities. However, the low solubility and poor stability of Cur limit its low bioavailability and multi-function. It is essential to develop effective measures to improve the unfavorable nature of Cur and maximize its potential benefits in nutritional intervention.
Scope and approach: The focus of this review is to emphasize the construction of lipo-solubility delivery vehicles for Cur, including emulsion, nanoliposome and solid liposome. In addition, the potential benefits of vehicles-encapsulated Cur in the field of precise nutrition were summarized, including high targeting properties and multiple disease interventions. Further, the deficiencies and prospects of Cur encapsulated in vehicles for precise nutrition were discussed.
Key findings and conclusions: The well-designed lipo-solubility delivery vehicles for Cur can improve its stability in food processing and the digestion in vivo. To meet the nutritional requirements of special people for Cur-based products, the improvement of the bioavailability by using delivery vehicles will provide a theoretical basis for the precise nutrition of Cur in functional food.
