Generation of bioactivities from proteins of animal sources by enzymatic hydrolysis and the Maillard reaction

Bioactive peptides generated from animal sources, such as dairy, meat, fish, and their by-products, are promising food ingredients for developing functional foods. The Maillard reaction plays an important role in most processed foods and generates various chemical components. Changes of peptides and reduced sugars by the Maillard are still not resolved enough. Since animal protein-derived peptides are widely utilized in many processed foods, it deserves concern and research on their changes by the Maillard reaction during processing or storage. This chapter briefly overviews bioactive peptides generated from animal sources of proteins, as well as bioactivities of Maillard reaction products generated from peptides.
