摘要:

对醋蛋中ACE 抑制肽的分离纯化及活性组分的稳定性进行初步研究。结果表明,醋蛋液经Sephadex G-50 和Sephadex G-15 分离后得到具有较高ACE 抑制活性的组分,该组分对酸碱、热及消化道酶系统具有较高的稳定性。

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
