    Patent number: 4759935
    Abstract: A bag for receiving apples 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 preserving the freshness of the apples when placed within the bag. The apples are placed within the bag and then an opening portion of the bag containing the apples, the ethylene absorbent and the deoxidant is sealed. The sealed bag allows air to permeate through it to a degree such that a minimum amount of air necessary for the apples is supplied in the presence of the ethylene absorbent and the deoxidant. The apples are stored in the sealed bag whereby maturing of the apples is delayed for preserving the freshness thereof.
