Abstract:
Application of bioactive phytochemicals in foods, supplements, and pharmaceuticals is often limited because of their poor solubility, stability, and bioavailability. Phytochemical oral delivery systems (PODS), consisting of phytochemical-loaded nanoparticles or microparticles, can overcome these challenges. PODS can be produced in liquid, gel, paste, or solid forms. They must be carefully formulated to be compatible with the product matrix, economical, robust, and maintain phytochemical bioactivity. This review evaluates recent advances in the development of PODS, including microemulsions, nanoemulsions, emulsions, solid lipid nanoparticles, liposomes, and biopolymer microgels. Properly designed PODS will increase phytochemical applications in commercial products.
