Abstract:

In this study, static adsorption capacity and desorption rate were measured to confirm the optimum manipulation parameters of macroporous resin for separating angiotensin converting enzyme inhibitory peptide (ACE-inhibitory peptide). The results showed that the best pH of sample for the desalination of ACE-inhibitory peptide is 2.0, and when 70% ethanol is used as eluent, the elution effect is the best and the salt concentration of sample is kept constant. In conclusion, DA201-C macroporous resin has excellent and comprehensive adsorption property, and can be used to separate ACE-inhibitory peptide.

Key words: macroporous resin, ACE-inhibitory peptide, static adsorption
