Research demonstrates effectiveness of κ-carrageenan films with limonene and curcumin for food freshness, suggesting they could enhance sustainable packaging solutions.
Key Points
The addition of curcumin and limonene results in color changes indicating chicken meat freshness, confirming the film's effectiveness as a freshness indicator.
FTIR analysis revealed key functional groups, while FESEM imaging showcased the film's dense structure and surface homogeneity.
The biodegradable κ-carrageenan films enriched with natural extracts provide not only indicators of spoilage but also antibacterial properties.
Future research is necessary to optimize extract concentrations and assess their efficiency across various food types for commercial use.
