This study aimed to assess the spatial variation in physicochemical properties within individual mangos, as well as to investigate the influence of initial ripeness level on physicochemical characteristics of fresh-cut mangos. Individual mangos were evaluated at 12 specific flesh positions in the inner and outer sides. Mango cubes of 1.5 cm prepared from three firmness stages were monitored for changes during 9 days of storage at 5 °C.
Mango fruit varied significantly in firmness and color based on spatial position, with the ripening direction from the inner flesh outward and from the stem end to blossom end. Limitations to fresh-cut mango quality were 'desiccation' (dried cut surface) and 'edge or tissue damage' (cut edge damage or brown and bruise-like appearance). Firmer texture and paler yellow of inner flesh were found in less mature mango fruit (P < 0.001). The optimal ripeness stage for fresh-cut mango products was 45 N, based on ease of handling, fresh appearance at the time of purchase and intermediate physicochemical properties (firmness, color and SSC/TA ratio).
Spatial variance and initial ripeness stage affect fresh-cut mango quality. Therefore, they must be considered by fresh-cut mango processors in order to attain optimal product quality. © 2015 Society of Chemical Industry.
本研究旨在评估单个芒果内部理化性质的空间差异,以及探讨初始成熟度对鲜切芒果理化特性的影响。对单个芒果内外侧的12个特定果肉位置进行了评估。从三个硬度阶段制备的1.5厘米芒果块在5℃下储存9天期间监测其变化。
芒果果实的硬度和颜色因空间位置而异,成熟方向是从内部果肉向外,从果柄端到花端。鲜切芒果品质的限制因素是“干燥”(切割表面干燥)和“边缘或组织损伤”(切割边缘损伤或褐色及类似瘀伤的外观)。在不太成熟的芒果果实中发现内部果肉质地更硬且黄色更浅(P < 0.001)。基于易于处理、购买时外观新鲜以及中等理化性质(硬度、颜色和SSC/TA比值),鲜切芒果产品的最佳成熟阶段为45 N。
空间差异和初始成熟阶段会影响鲜切芒果的品质。因此,鲜切芒果加工商必须考虑这些因素,以获得最佳产品质量。© 2015化学工业协会。
