Abstract: 
This investigation was carried out to evaluate the extent of bioactive peptides that can be obtained from proteolytic enzymes, including alcalase, flavorzyme, neutrase, and protamax. For this purpose, whey protein concentrate (WPC) was hydrolyzed, spray-dried, and subjected to mass spectrometric analysis. In addition, offline-electrospray-ionization-mass spectrometry (ESI/MS) measurements and offline-matrix-assisted laser desorption/ionization mass spectrometry (MALDI/MS) measurements were compared to determine analytical adequacy. Samples treated with alcalase for 3 hours produced various bioactive peptides, suggesting the possible application of this method to functional food preparations. Comparison of both ionization methods indicated ESI/MS as suitable for the identification of peptides from whey protein hydrolysates.
