Preparation and potential applications of casein-polysaccharide conjugates: a review.

Glycation of casein and caseinates with polysaccharides via Maillard reaction is a simple and environmentally safe way to prepare new food ingredients of improved functional properties. Sodium caseinate has been used mainly to prepare conjugates with several polysaccharides particularly maltodextrins and dextrans. The functional properties of these conjugates are influenced by the used polysaccharides and heating conditions. Under optimal heating conditions substantial improvements have been evident in their emulsification and foam properties of these conjugates. Casein-polysaccharide conjugates have several potential applications in food processing and microencapsulation. This article gives an overview on their formation and potential uses.
