Article Synopsis
- Researchers created smart films using starch, pectin, and purple carrot peel (PCP) that contain anthocyanins, enabling them to act as pH-responsive tags for monitoring plant-based chicken products.
- They tested different forms of PCP (powder and extracts) and found that films with higher PCP concentrations improved strength and water resistance while effectively responding to pH changes.
- The study demonstrated that these films changed color significantly over three days when used on chicken equivalents, highlighting PCP's potential as a natural colorant and indicator in food packaging.
In this work, novel nanocomposite films based on babassu coconut mesocarp and zinc oxide nanoparticles (ZnO NPs), synthesized by a green route, were produced for application as food packaging films. The films were prepared using the casting method containing different contents of ZnO NPs (0 wt%, 0.1 wt%, 0.

Both of these polymers are restricted from being separated in several ways. An easier way to reuse them in new applications, without the need for separation, would require them to be less immiscible.
