Abstract:

The specific active peptides in milk can inhibit the activity of angiotensinⅠ-converting enzyme effectively
to execute antihypertensive effect. Due to different structures of milk-derived ACE inhibitory peptides, the peptides
are not able to pass through the intestinal mucosa into blood circulation when administered orally. Therefore, not
all ACE inhibitory peptides have the function of lowering blood pressure and a low oral bioavailability. This article
has introduced current research status and activity evaluation as well as the intestinal absorption mechanism of milkderived
ACE inhibitory peptides, which includes intestinal ingestion, metabolic activity and intestinal excretion using
Caco-2 cell model. In addition, a prospect of improving oral bioavailability of milk-derived ACE inhibitory peptides
has also been proposed.

Key words: Caco-2 cell model, milk-derived ACE inhibitory peptide, absorption mechanism of peptide
