Abstract: Marine bioactive peptides have become a hot research topic in food industry,because they have many advantages,such as functional diversity,extensive sources,strong specificity,small poisonous side effects,etc.At present,a lot of researches on marine bioactive peptides are carried out both at home and abroad. This paper summarized the results of the research in recent years from two angles including sources( e.g.direct extraction and controllable enzymatic hydrolysis) and functions( e.g.anti- fatigue,anti- tumor,anti- oxidant,anti- hypertension,etc).Finally,the prospect based on the problems of the present researches was made.
