摘要

•A simpler strategy was carried out to identify dipeptides in dry-cured ham.•Ultrafiltration following MALDI-ToF MS allows a rapid peptide identification.•AH, AL, DD, EV and VF were identified in samples with different processing times.•Bioactive or tasting food-derived dipeptides can be identified by this methodology.
