Abstract:

Tomato is a highly perishable commodity the quality and shelf life of tomatoes are significantly affected by the fungal attack and oxidative deterioration. To reduce spoilage the efficiency of active packaging based on polylactic acid (PLA) which is a biodegradable material extracted from corn or sugarcane was evaluated on tomatoes. This active packaging was incorporated with eugenol antifungal compound extracted from clove essential oil and lycopene antioxidant compound with free radical scavenging activities extracted from tomato. The freshly harvested tomatoes were taken and active packaging treatments were applied. The experiment was conducted with four treatments which were, control without any scavenging agent and three treatments with eugenol (0.1, 0.3, and 0.5%) and lycopene (10, 20, and 50µg) and then stored under controlled conditions (10-15?). Afterward, monitoring of fungal growth on tomatoes using microbial plate counting methods was determined and the oxidative stability of the tomatoes was evaluated by measuring lipid oxidation markers, such as peroxide value or thiobarbituric acid reactive substances (TBARS). Additionally, the sensory attributes, including color, texture, and flavor, were evaluated also. The release kinetics of the incorporated chemicals was also investigated. All the treatments performed well in enhancing the shelf life in contrast to the control treatment but the 4 treatment had significant results. By increasing the concentration of eugenol and lycopene the quality and shelf life of tomato increased. The findings of this study have important implications for the tomato industry since active packaging options with antifungal and antioxidant compounds may offer a practical way to maintain the quality and shelf life of tomatoes. These active packaging methods have the potential to decrease postharvest losses and improve consumer satisfaction by preventing fungal growth and oxidative deterioration. Continued research in this field is crucial to optimize active packaging formulations and validate their practical implementation in the tomato industry.
