Histidine-containing Dipeptides: Properties and Occurrence in Foods

Histidine-containing dipeptides carnosine, anserine, and balenine are natural constituents in mammalians, which are known to contribute to relevant bioactive functions during postmortem processing of muscle foods. The knowledge of the content of these dipeptides in meat, poultry, and seafood is very important for the characterization of its biological value in different muscles and cuts and how its antioxidant benefits may be affected by processing or during the storage. This article is describing the importance for health, the availability, and the occurrence of histidine-containing dipeptides in meat, poultry, and seafood as well as the description of the main available methods for their analysis in foods.
