Overview

Evaluation shows chitosan-ε-polylysine films significantly improve microbial growth control and oxidation in tuna.

Key Points

  • Composite films reduced total volatile basic nitrogen by 43%, indicating better preservation of tuna quality.
  • Myoglobin oxidation was significantly inhibited, retaining more metmyoglobin in treated fish compared to controls.
  • Lipid oxidation was delayed, as shown by lower TBA values of 0.55 mg/100g in treated tuna.
  • This multifunctional preservation system extends the shelf life of tuna by over 40% under refrigeration at 4°C.
