ABSTRACT:
Fruit is prepared for refrigerated storage by cutting the fruit into convenient pieces, and then subjecting the fruit to soaking under vacuum in a solution containing sodium bisulfite or sodium sulfite and citric acid in definite ranges. These ranges are preferably inversely related in a substantially straight-line relationship, so that the high end of one range is used in conjunction with the low end of the other. The fruit pieces are also preferably immersed in a preliminary holding solution containing sodium bisulfite or sodium sulfite and table salt prior to the soaking. Fruit prepared in this way can be held indefinitely under ordinary refrigeration without freezing. The process is particularly suitable for apples.
