Fruit softening is a biochemical process, normally
attributed to the deterioration in cell wall composition
that involves the hydrolysis of pectin by enzymes. Low
levels of oxygen and elevated levels of carbon dioxide
restricted the activities of these enzymes and allowed
retention of the fruit firmness during storage. Moreover,
water counted and the rachis appearance was rated. Gray
mold infected grapes were identified by the
characteristic slip-skin symptom and sporulation
