Abstract:

The isolation and stability of ACE inhibitory peptide of vinegar-egg were studied in this paper. The results showed that the fraction C with higher ACE inhibitory activity was obtained from the vinegar-egg hydrolyzates by Sephadex G-50 and Sephadex G-15 gel filtration chromatography. This fraction demonstrated high stability against different pH and temperature as well as gastrointestinal proteases.

Key words: vinegar-egg, ACE inhibitory peptide, isolation, stability
