Implication

Novel approach using high-pressure processing enhances gelatin yield and quality from fish skin, suggesting a sustainable alternative.

Key Points

  • This research focuses on optimizing the extraction of gelatin from red tilapia skin using high-pressure processing (HPP).
  • Explored gelatin extraction from red tilapia skin using high-pressure processing and conventional methods.
  • Evaluated the yield and quality of gelatin produced by both methods.
  • Characterized gelatin's microstructure and gel strength using standard testing methods.
  • HPP method yielded 1.24 times more gelatin than conventional methods.
  • Gelatin from HPP displayed 1.45-fold higher gel strength than gelatin extracted conventionally.
  • The optimal pressure for gelatin production was found to be 250 MPa, balancing yield and quality.
