Effect of calcium ions on apple fruit softening during storage and ripening.

The hypothesis that apple fruit softening results from loss of calcium from ionic linkages between pectin molecules in the middle lamella was tested by infiltration of apple fruit tissue (cultivars Cox's Orange Pippin, Bramley's Seedling and Gloster 69) with calcium acetate solutions. Infiltration partially reversed softening that had resulted from delayed harvesting, storage in air or 1.25% O2 at 3.5 deg C, and ripening at 10 deg in air. It was concluded that loss of calcium from the middle lamella is a contributing factor to softening, but other factors are also involved.
