Eco-Friendly Cling Film Based on Alizarin and Carbon Dot-Modified PVA/SA Matrix for Enhanced Cherry Tomatoes Preservation.

Eco-Friendly Alizarin and Carbon Dot Film Keeps Cherry Tomatoes Fresher for Longer

Researchers from Northeast Forestry University developed an eco-friendly cling film made of alizarin and carbon dots embedded in a PVA/SA matrix. This bio-based film enhances antioxidant and antibacterial protection, keeping cherry tomatoes fresh for over 13 days—marking a breakthrough in sustainable food preservation.
