ABSTRACT:
A method and an apparatus for detecting rotten albumen in broken raw eggs which may include sound yolk are disclosed. The apparatus includes a device for casting ultraviolet light onto the albumen, an optical filter system filtering a complex of fluorescence of the albumen and the yolk and an ultraviolet light reflected from or transmitted through the albumen so as to transmit only the components due to fluorescence of the albumen, and a discriminator which compares the level of a signal corresponding to the fluorescence of the albumen to a threshold level corresponding to the fluorescence of the sound albumen. The method and the apparatus are applicable to both separating-type and nonseparating-type automatic egg breakers.
