Abstract：
This study aimed to assess the post-harvest dynamics of seedless conical and mini-conical pepper cultivars in terms of fruit weight loss, dry matter content, and soluble solid content. The above parameters were demonstrated to be effective commercial pepper shelf-life indicators. The commercial quality of pepper fruit intended for export was evaluated weekly under simulated fruit storage conditions for over 28 d. Results revealed that fruit weight loss, dry matter content, and soluble solid content were affected by cultivar type and storage duration. Additionally, a strong correlation between these variables was observed confirming their linear relationship which was more profound between dry matter and total soluble solid content. Daily changes during storage were similar in both seedless conical and mini-conical peppers, while the fruit weight loss daily rate was greater than that of dry matter. Water loss was identified to be the main factor causing reduced fruit quality. Solid content reduction occurred predominately during the initial storage period. Notably, fruit with lower dry matter content at harvest tended to maintain their commercial quality for a longer time due to their ability to resist water loss without any visible signs of deterioration, which is beneficial during prolonged storage.
摘要：
这项研究旨在评估无核圆锥形和迷你圆锥形辣椒品种在果实失重方面的收获后动态，干物质含量,和可溶性固体含量。以上参数被证明是有效的商业辣椒保质期指标。在模拟水果贮藏条件下，每周对出口辣椒果实的商业品质进行28d以上的评价。干物质含量,可溶性固形物含量受品种类型和贮藏时间的影响。此外,观察到这些变量之间的强相关性，证实了它们的线性关系，这在干物质和总可溶性固体含量之间更为深刻。无核圆锥形和迷你圆锥形辣椒在储存过程中的每日变化相似，而果实的日失重率大于干物质的日失重率。失水被认为是导致果实品质下降的主要因素。固体含量减少主要发生在初始储存期间。值得注意的是,收获时干物质含量较低的果实，由于它们能够抵抗水分流失而没有任何明显的变质迹象，因此倾向于在更长的时间内保持其商业品质。这在长期储存期间是有益的。
