Abstract
Systems and methods for treating unwashed fruit with fruit bloom that provide a first ultraviolet (UV) energy with one or more flashes using a first set of one or more flash lamps to a first surface of each of a plurality of blueberries and provide a second UV energy with one or more flashes using a second set of one or more flash lamps to a second surface of each of the plurality of blueberries. The system determines a fruit bloom level associated with the plurality of blueberries after provision of the first and second UV energies and determines an adjustment to a parameter of at least one of the first and second UV energies based on the fruit bloom level. The system provides UV energy with the adjusted parameter to a subsequent set of blueberries to remove microorganisms from the blueberries while retaining fruit bloom.
