CONSTITUTION:For example, when a single food such as melon or apple is frozen and stored, the single food is washed, sterilized, subjected to a food discoloration- preventing treatment, coated with the juice of the single food and subsequently vacuum- sealed in a vinyl resin inner bag 1B. After cooled below a just freezing temperature, the inner-packaged food is packed with an intermediate vinyl resin bag having projections 1D1 for maintaining spaces on the inner surface thereof. The second juice 1E comprising salt, gelatin and the juice having a higher concentration than that of the first juice coated on the food is received in the intermediate bag, sealed and cooled below a just freezing temperature. The packed food is placed in an outer bag similar to the intermediate bag, and a prescribed volume of water is injected into the bag. The packed food is sealed with the outer bag and subjected to the objective freezing treatment.
