| Abstract: | Caseinophosphopeptides (CPPs) are phosphorylated casein-derived peptides which possess the ability to bind and solubilise minerals, such as Ca2+. The high bioavailability of Ca2+ fram milk and dairy products has been attributed to the production of CPPs which are produced following digestion of casein by the action of gastrointestinal proteinases. CPPs, which appear to be resistant to extensive proteolytic degradation, accumulate in the distal small intestine where they are purported to play a role in enhancing the passive absorption of Ca2+ and other trace elements. A recent human feeding tral reported improved Ca2+ and Zn2+ absorption following CPPs incorporation into food. This review summarises the production, characterization and potential applications of CPPs. |
