This study investigates the impact of various packaging materials on the postharvest quality and shelf life of bell pepper (Capsicum annuum L. var. grossum Sendt) fruits. Conducted at ITM University, Gwalior, the experiment involved 14 different treatments, including polythene, cotton, aluminum foil, jute bags, and more, with observations recorded on the 0th, 4th, 8th, 12th, 16th, and 20th days. Results indicated that polythene (T₂) was the most effective packaging material, consistently maintaining the highest polar and equator diameters, and fruit firmness throughout the storage period. Polythene-packaged fruits showed reduced ethylene production, delayed ripening, and better preservation of structural integrity. Additionally, aluminum foil (T₅) excelled in maintaining high Total Soluble Solids (TSS) content, while jute bags (T₈) were most effective for Titratable Acidity, and polythene (T₂) maintained the highest Ascorbic Acid content. The control group (T₁) consistently showed the lowest values across all measured parameters, underscoring its ineffectiveness. These findings highlight polythene's superior performance in reducing moisture loss and preserving fruit quality, making it a viable option for extending the shelf life and marketability of bell peppers. The study provides valuable insights for growers, distributors, and consumers seeking effective postharvest management strategies for bell peppers.
