Comparison of texture properties of post-harvested apples using texture profile analysis

Changes of texture properties of harvested Fuji and Gala apples were monitored and compared by using texture profile analysis with the stable microsystem texture analyzer. The correlation coefficients between those texture parameters were also analyzed. It was found that fruit adhesiveness had negative correlations with hardness, fracturability, cohesiveness and other texture parameters. There were positive correlations between apple texture parameters i.e. cohesiveness is correlated with hardness, resilience and chewiness, respectively (R＝0.86～0.95). The values of resilience correlated well with the measured parameters excluding springiness and adhesiveness (R=0.67～0.95). It was concluded that parameters of fracturability, adhesiveness, cohesiveness, resilience and chewiness could provide basis for reliable evaluation of texture properties of apple fruits. Texture of Gala apples was more likely to become mealy than Fuji apples during post-harvest storage.
