Abstract

Abstract An improved process for obtaining dried fruit, notably prunes, is described. The picked fruit is treated, either immediately after having first been subjected to blanching, or a few days after picking and following partial dehydration, or after lengthy preservation. They are subjected to two successive steps: (a) enriching of the fruit by the penetration of its cells by a sugar, sweetening product or other substance enabling the dry extract of the fruit to be increased by osmosis, and (b) dehydration which permits a more or less large amount of the water contained in the fruit cells to be extracted. The invention therefore consists in an enriching of the fruit followed by a dessication. Said process, applied notably to the Ente plum, enables a larger gauge size prune of improved flavor to be obtained.
