  • Patent number: 4364968
    Abstract: A process for preparing dried grapes which are further processed to remain desireably soft with minimal color, flavor, or textural changes over extended periods of time. The process combines the use of enzyme inactivation and a hydrophillic carbohydrate infusion into fresh grapes, followed by drying the grapes to a moisture content of less than 30%. The dry grapes are then converted into simulated raisins by storing the dry grapes for a period of time under controlled humidity and at an elevated temperature effective to provide a darkening in color and to develop a natural raisin-like flavor within the grapes without further drying of the grapes.
