Abstract:The research of antihypertensive peptide （AHP） derived from all kinds of foods was a hot topic in recent years because they showed strong angiotensin converting enzyme（ACE） inhibitory activity and significant antihypertensive effect in vitro experiments and animal experiments， so it supplied a new safe and effective way to produce antihypertensive product. In this paper， the research progress and general situation of antihypertensive peptide derived from food were summarized， and especially the technology of preparation and the relationship between the peptides and their structures were discussed and the prospect of AHP from the foods in the fields of research and application wasexpected.
