摘要

Tomatoes are highly perishable, with post-harvest losses significantly impacting their marketability and shelf life. Proper packaging can mitigate these losses by reducing physiological weight loss (PLW), spoilage, and quality deterioration. This study aimed to evaluate the effect of different packaging films—low-density polyethylene (LDPE), high-density polyethylene (HDPE), polypropylene (PP), shrink film, and cling film—on the storage life and quality attributes of tomatoes (Solanum lycopersicum cv. Punjab Varkha Bahar 4) under ambient (17.4–19 °C, 25–28% RH) and cold (10 ± 1 °C, 90–95% RH) storage conditions. The results indicated that all packaging films significantly reduced PLW, spoilage, and biochemical degradation compared to control fruits. Cling film-wrapped tomatoes exhibited the lowest PLW (3.31% ambient, 3.63% cold) and spoilage (25.70% ambient, 11.11% cold), while maintaining higher fruit firmness (20.56 N force ambient, 21.40 N force cold) and superior biochemical properties, including ascorbic acid (17.16 mg/100 g ambient, 19.22 mg/100 g cold) and total phenolics (2.74 mg/100 g ambient, 2.70 mg/100 g cold). Lycopene content initially increased but declined after 9 days in ambient and 21 days in cold storage. Cling film extended storage life to 9 days in ambient and 21 days in cold conditions, compared to 3 and 7 days, respectively, for control fruits. Overall, cling film was the most effective in preserving tomato quality and extending shelf life by modifying atmospheric conditions, delaying ripening, and reducing metabolic degradation. These findings highlight the potential of optimized packaging solutions for enhancing the post-harvest storage of tomatoes.
