Zusammenfassung:•An extraction process was found to produce a specific peptide from cucumber seed.•The calcium-chelating ability of different peptide components was evaluated.•The differences of characterization between CSP3 and CSP3-Ca chelate were given. A specific cucumber seed peptide (CSP) was successfully produced by liquid state fermentation with B. subtilis HYT. Then the CSP was divided into four kind molecular weight components (CSP, untreated; CSP1, MW>10kDa; CSP2, 6kDa
