Emulsions delivery systems of functional substances for precision nutrition.

Many functional substances are chemically unstable and exhibit variable water/oil solubility, reducing their bioavailability and efficacy. It is necessary to devise effective measures to improve the unfavorable properties of functional substances and maximize their potential benefits in nutritional interventions. Therefore, the development and application of edible emulsion-based delivery systems for these functional substances using food-grade materials would be highly beneficial for the food industry. In recent years, Pickering emulsions have garnered significant attention in the scientific community due to their characteristic of being free from surfactants. This section focuses on emphasizing the design and preparation of emulsion delivery systems based on functional substances. Additionally, we summarize the current applications of emulsion delivery systems in functional substances. This chapter also discusses the potential advantages of Pickering emulsion systems in the precise nutrition field, including high targeting specificity and nutritional intervention for various diseases. Well-designed Pickering emulsion delivery carriers for functional substances can enhance their stability in food processing and in vivo digestion. To meet the nutritional needs of specific populations for functional foods, utilizing emulsion delivery systems to improve the bioavailability of functional substances will provide a theoretical basis for the precise nutrition of functional substances in functional foods.
