Özet

The objective of this study was to determine the bioactive potential of hazelnut meal protein hydrolysates. Hazelnut meal protein isolate was hydrolyzed using Alcalase and Trypsin + Chymotrypsin to 23.5% and 13.7% degrees of hydrolysis, respectively. The peptide fractions (< 5 kDa and > 5 kDa) were screened for the in vitro inhibition of angiotensin I-converting enzyme (ACE), dipeptidyl peptidase-IV (DPP-IV), and alpha-glucosidase activities. Peptide fractions > 5 kDa showed a higher potency to inhibit ACE (IC50 = 0.10-0.13 mg/mL), whereas peptide fractions < 5 kDa were more effective in inhibiting DPP-IV (IC50 = 0.37-0.45 mg/mL) and alpha-glucosidase (IC50 =3.62-3.89 mg/mL), with no significant difference in treatment with Alcalase and Trypsin + Chymotrypsin. The results of the study showed that hazelnut meal protein is a potential source of bioactive peptide delivery and that the hydrolysates obtained could be used as an alternative ingredient for the development of new functional foods.
