Abstract：Food-derived peptides are new kinds of proteolytic products derived from food proteins by enzyme hydrolysis, separation, and purification. This article reviewed the present researches on nutrition and health function, production method, evaluation and recognization of the food-origin peptides, and current situation of quality standard. Also, the traditional food contained bioactive peptides and the terminal food that has been commercialized were overviewed and summarized. Finally, the application prospect of food- origin peptides was described.
Key words: food- origin peptides; nutrition and health protection function; production method; quality standard; terminal food
