A method of separating selected fruit from a volume of fruit is based on the reflectivity of the selected fruit. The method utilizes an automated optical inspection and sorting system to illuminate a volume of fruit including cranberries characterized by a spectral power distribution in the infrared spectral region. The system detects reflections of wavelengths of the illumination in the infrared spectral region, identifies the selected fruit based on the detected reflectivity, and sorts the selected fruit from the volume of fruit.


[ We claim:] [1.] A method of separating selected specimens of fruits and vegetables that have been subject to bacteria or rot from a volume based on an amount of reflected light from the volume, comprising:illuminating the volume with infrared light having a wavelength range; the volume containing acceptable specimens having highly reflective chlorophyll within the wavelength range and unacceptable specimens that have diminished chlorophyll reflectivity within the wavelength range due to rot or bacteria;establishing a value of reflected light from the v...
