Functional changes of apple cell membranes during storage.

Physical characteristics, chemical composition and storage disorders of Jonnee, Jonagold, Jonathan, Redspur, Gloster and Mutsu [Crispin] apples were studied. Membrane processes occurring during storage were also studied in order to derive mathematical models that could be used to predict quality changes during fruit storage. Redspur and Mutsu fruits had the lowest soluble solids content with the lowest fructose:glucose ratio. Jonnee and Redspur had the lowest incidence of storage disorders. Higher incidences of disorders occurred in later harvested apples and the rate increased exponentially during storage. Ion leakage (L60) from the cell increased significantly by 10-15% during 5-7 months' storage. Differences in leakage among the apple cultivars were significant. The high incidence of disorders in Jonathan fruits was reflected in high L60 values. The mathematical model derived to characterize the membrane processes during storage shows that when storage disorders increase, membrane permeability also increases resulting in higher ion leakage rates.
