ABSTRACT

This study aimed to assess the effects of cultivation system (organic and conventional) and modified atmosphere packaging (MAP) treatments on quality characteristics and bioactive compounds of tomato fruit (Solanum lycopersicum cv. Şencan 9) stored in cold storage conditions, at 8°C ± 0.5°C and 90% ± 5% relative humidity, for 21 days. At the end of the cold storage period, lower weight loss and respiration rates were measured in the organically produced fruit compared with the fruit produced in the conventional production system. On day 14 and 21 of storage, higher firmness was measured in the conventional- and organic-MAP treatments and in the conventional-unwrap treatment than in the organic-unwrap treatment. On day 7, L* and hue angle measured in organic-MAP were significantly higher than in the other treatments. At the end of the cold storage period, higher soluble solids content, vitamin C, total phenolics, total flavonoids, and antioxidant activity were recorded for the organic tomatoes, compared with the conventionally grown fruit. The highest and lowest concentrations of total flavonoids and antioxidant activity were determined in organic-MAP and conventional-unwrap treatments, respectively. In conclusion, it was shown that the quality of the tomatoes grown in the organic production system and stored in MAP maintained higher quality characteristics during the cold storage period.

摘要

本研究旨在评估栽培系统（有机和常规）和气调包装（MAP）处理对番茄果实（Solanum lycopersicum ）品质特性和生物活性化合物的影响简历。Şencan 9) 在 8°C ± 0.5°C 和 90% ± 5% 相对湿度的冷藏条件下储存 21 天。在冷藏期结束时，与传统生产系统生产的水果相比，有机生产的水果的重量损失和呼吸速率较低。在储存的第 14 天和第 21 天，测量到常规和有机 MAP 处理以及常规展开处理中的硬度高于有机展开处理。在第 7 天，有机-MAP 测量的 L* 和色调角显着高于其他处理。在冷藏期结束时，与常规种植的水果相比，有机番茄的可溶性固形物含量、维生素 C、总酚类物质、总黄酮类化合物和抗氧化活性均较高。在有机 MAP 和常规展开处理中分别测定了总黄酮和抗氧化活性的最高和最低浓度。综上所述，表明有机生产系统中种植并储存在 MAP 中的西红柿的品质在冷藏期间保持了较高的品质特征。
