Abstract:

Changes in texture properties of peach fruits (cultivars ‘Shuangjiuhong’ and ‘Kawanakajima Hakuto’) were
investigated by texture profile analysis (TPA) during postharvest storage. The results showed that the hardness, adhesive
force, adhesiveness and chewiness of fruits from both cultivars indicated a rapid increase to the maximum levels during
storage, and then exhibited a decline. These parameters in ‘Shuangjiuhong’ fruits were significantly higher than in
‘Kawanakajima Hakuto’ fruits (P < 0.01) at the same storage stage. Deformation was increased in ‘Shuangjiuhong’
fruits during storage, which was contrary to that of ‘Kawanakajima Hakuto’ fruits. Cohesiveness in both peach cultivars
exhibited gentle change during storage, and there was no significant difference between them. Correlation analysis indicated
significantly positive correlation (P < 0.01) between fruit hardness and adhesive force, adhesiveness or chewiness and no
obvious correlation among elasticity, cohesiveness and other parameters was observed.
