Peaches are climacteric and highly perishable fruits, with a short shelf life, and are prone to rapid deterioration after harvest. In this study, the chemical proprieties, aroma profile and a sensory evaluation were conducted to: (1) characterize and compare fruits of 13 different peach and nectarine cultivars, harvested at physiological maturation; and (2) assess the suitability of these cultivars, that are successfully used in long food supply chains (LFSCs), for their use in short food supply chains (SFSCs). Through statistical analysis clear differences were found among the studied cultivars, and in particular between cultivars suited to SFSCs compared to those suited for LFSCs. Results indicate that, despite all cultivars being planted in the same orchards and with the same pre-harvest management and practices, their post-harvest performances were mainly influenced by the cultivar genetic makeup. Therefore, cultivars conventionally used in SFSCs, such as "Guglielmina" and "Regina di Londa", had the best aroma, sweetness and juiciness compared to LSCPs ones. In contrast, the LSCPs varieties showed interesting values for firmness and crunchiness.
桃子是跃变型且极易腐烂的水果，货架期短，采后容易迅速变质。在本研究中，对桃子进行了化学特性、香气特征分析和感官评价，目的是：（1）对13个不同桃和油桃品种在生理成熟时采收的果实进行特性分析和比较；（2）评估这些成功应用于长食品供应链（LFSCs）的品种在短食品供应链（SFSCs）中的适用性。通过统计分析发现，在所研究的品种之间存在明显差异，特别是适合短食品供应链的品种与适合长食品供应链的品种之间。结果表明，尽管所有品种都种植在相同果园且采用相同的采前管理和措施，但它们的采后表现主要受品种基因构成的影响。因此，与用于长食品供应链的品种相比，传统上用于短食品供应链的品种，如“古列尔米纳”和“隆达女王”，具有最佳的香气、甜度和多汁性。相反，用于长食品供应链的品种在硬度和脆度方面表现出有趣的数值。
