Pancreatic hydrolysis of bovine casein: Peptide release and time-dependent reaction behavior

► A total of 297 peptides was identified from casein pancreatic hydrolysates during 24 h digestion. ► Many potential bioactive peptides exist in the hydrolysates. ► Pancreatic hydrolysis with the rates at the order: β-CN > αs1-CN > αs2-CN > κ-CN. ► Reaction behaviors of individual caseins upon pancreatic hydrolysis were compared.
