To create intelligent packaging films that indicate chicken spoilage through color changes.
Developed pH-sensitive starch/LCNF films
Incorporated blueberry anthocyanins into the films
Assessed color changes with spoilage progression
Films changed color from red to grayish-purple as spoilage occurred
Demonstrated clear visual indication of chicken freshness
Abstract
pH-sensitive starch/LCNF films incorporating blueberry anthocyanins were developed for intelligent chicken packaging, exhibiting distinct color changes from red to grayish-purple as spoilage progressed.
