ABSTRACT:
A process for enhancing the detection of larvae or worms in shelled pecans for separation and removal therefrom. In carrying out the process, the shelled pecans are soaked in a solution comprising a water soluble, edible, non-fluorescent material dissolved in water to coat the pecans with the material. The pecans are removed from the solution, dried, and illuminated with ultraviolet light. The material does not adhere to the worms whereby it does not affect their fluorescence but prevents the pecans from fluorescing whereby the worms may be readily detected and separated. The color of the material used is such that it does not significantly affect the appearance of the pecans when coated therewith.
