Towards a kinetic model of the central metabolism of apple during controlled-atmosphere storage and shelf life
Fundamental understanding of the controlled atmosphere (CA) stress response of apples is crucial to further optimize the storage conditions. In this research, a kinetic model was developed to investigate the adaptation mechanism of apples to CA stress and the metabolic responses afterwards during shelf life. A metabolic network model was constructed consisting of sucrose metabolism, glycolysis, the tricarboxylic acid cycle, and amino acids branching from these pathways (alanine, valine, glutamate, aspartate and γ-aminobutyrate). The results showed the model was able to capture the dynamics of metabolic changes during storage and shelf life. Furthermore, the model provided insights into the stress response of the fruit.
