Effect of different packaging films under modified atmosphere on the shelf life of papaya slices

Abstract

This study investigates the impact of various packaging materials on the quality of ready-to-eat papaya over seven days using modified atmosphere packaging (MAP). The tested materials included conventional PA/PE films and biopolymer-based films: film bio high-performance formulation barrier (B), advanced barrier (AB), and stiffer advanced barrier (SAB). Results showed that biopolymer films, especially B, effectively preserved the quality of papaya. These films reduced the increase in total soluble solids content (TSSC), maintained higher total sugars, and better retained vitamin C, particularly in AB samples, without affecting mineral content. Sensory evaluations indicated no significant differences among packaging materials, though papayas in B film were preferred for their juiciness and exotic flavor. The study monitored physicochemical parameters, vitamin content, and sensory attributes. Findings suggest that biodegradable, compostable films are a sustainable alternative to conventional PA/PE films, as they maintain fruit quality, reduce weight loss, and limit browning, thereby extending the shelf life of ready-to-eat papaya.
