Abstract
Abstract A bag for receiving the apple is prepared. An ethylene absorbent and a deoxidant are placed in the bag, each of the absorbent and the deoxidant being in an amount such that ethylene biosynthesis is suppressed for keeping freshness of the apple when the apple is placed within the bag. The apple is placed within the bag and then an opening portion of the bag containing the apple, the ethylene absorbent and the deoxidant is sealed. The sealed bag allows air to permeate through it to a degree such that minimum amount of air necessary for the apple is supplied in the presence of the ethylene absorbent and the deoxidant. The apple is stored in the sealed bag whereby mature of the apple is delayed for keeping freshness thereof.
