Biopolymer microgels have considerable potential for their ability to encapsulate, protect, and release bioactive components, such as vitamins, nutraceuticals, enzymes, and antimicrobials.  Biopolymer microgels consists of small particles (typically 100 nm to 1000 mm) whose interior consists of a three-dimensional network of cross-linked biopolymer molecules that traps a considerable amount of solvent. Biopolymer microgels are typically prepared using a two-step process involving particle formation and particle gelation.  This presentation reviews the design, fabrication and utilization of biopolymer microgels as delivery systems in foods.  The major constituents and fabrication methods that can be used to prepare microgels are discussed.  The most important characteristics of microgel particles that can be designed to alter their functional attributes are reviewed (such as size, shape, structure, composition, and electrical properties). Finally, recent examples of the utilization of biopolymer microgels to encapsulate, protect, or release bioactive agents is given.<br/>
