Pomegranate Peel and Curly Dock Root Extracts for a Smart Use of Packaging

Packaging plays a crucial role in extending the shelf life of fresh fruits and vegetables, thereby preserving their quality characteristics throughout the supply chain. Packaging systems treated with natural compounds can replace synthetic packaging systems. This study aimed to evaluate the potential application of Active Cardboard Packaging (ACP) in preserving fruit quality and extending its shelf life. We observed the effect of cardboard packaging containing Punica granatum peel extract (PPGE) and Rumex crispus root extract (RRCE) on the shelf life of strawberries, tomatoes, and table grapes. In vitro and in vivo tests demonstrated the ability of these extracts to inhibit fungal growth. It can be hypothesized that RRCE+PPGE and PPGE, once incorporated into the packaging, create a system capable of inhibiting microbial growth, thus prolonging the freshness and marketability of the fruit. Quality was also assessed by measuring the surface color of homogenized strawberries, tomatoes, and grapes using a spectrophotometer. This study offers a novel approach to extending the shelf life of fruits and vegetables.
