Implication

This research established a process for preparing bioactive peptides from Antarctic krill, highlighting antioxidant and antihypertensive effects.

Key Points

  • AKPs demonstrated high antioxidant activity, with scavenging rates reaching 99.58% for DPPH at 30 mg/mL.
  • The IC50 for angiotensin-converting enzyme inhibition was 0.27 mg/mL, indicating notable antihypertensive potential.
  • AKPs inhibited α-glucosidase and dipeptidyl peptidase IV by 12.15% and 16.89% respectively, showcasing hypoglycemic effects.
  • Comprising 39 distinct bioactive peptide sequences, AKPs reveal diverse potential applications in health products.
