Outline of Final Research Achievements

This study aimed to evaluate the strain energy of fruits and fruit caps in order to contribute to the optimum packaging design in order to suppress the occurrence of fruit cap-like browning fruits that occur during distribution. As a result, we proposed a mathematical model that can estimate the energy absorption ratio and integrated amount of fruits and fruit caps during transportation according to the Young's modulus of peach fruits, which was assumed to have a constant fruit hardness.

Academic Significance and Societal Importance of the Research Achievements

モモ果実は軟化しやすく，流通中にフルーツキャップ状の褐変が生じ，品質低下が著しく流通が困難な果実であるが，本研究で提案した数理モデルを使用することで，フルーツキャップの硬さや流通時の加速度条件を種々の条件でシミュレーションすることが可能となり，食品ロスを抑えた最適な緩衝包装設計に貢献することができる．
