Food proteins have gained increasing value in recent times and have become an interesting issue for scientific research due to the rapidly expanding knowledge about physiologically active peptides. Bioactive peptides released during gastrointestinal digestion or food processing such as fermentation, curing and ageing, and enzymatic hydrolysis, play an important role in metabolic regulation and modulation, suggesting their potential use as functional food ingredients for health promotion and disease risk reduction. A substantial amount of evidence indicates that animal proteins and peptides...
