Paper Abstract

A new sensing technique was investigated to nondestructively measure the peel thickness of oranges destined for fresh market consumption. Coherent polarized laser emissions diffused by the subcuticular layers of the peel were filtered and imaged into a matrix CCD camera. Images were analyzed using conventional high-speed pixel operations. Resulting correlations suggest that this method may be a successful tool in real-time food processing operations providing the packer and the consumer with an objective evaluation of peel thickness, and subsequently, edible volume, juice content, and the ease with which the peel can be removed.
