Overview

This research develops a pH indicator film to monitor freshness in sardines and catfish, suggesting practical applications for perishable products.

Key Points

  • The developed pH indicator films indicate fish freshness through observable color changes during storage.
  • Physicochemical analysis shows increased thickness and decreased moisture content with higher concentrations of butterfly pea extract.
  • Films were tested on sardines and catfish at 4°C, with quality declines noted through pH and Quality Index scores over time.
  • The color of the films changed significantly, showcasing their potential effectiveness in freshness monitoring.
