Nondestructive Determination of Internal Quality in Peaches and Nectarines

A nondestructive optical method for determining the internal quality of intact peaches and nectarines was investigated. The method, based upon visible and near-infrared spectrophotometric techniques, was capable of simultaneously predicting the soluble solids content (r = 0.92), sucrose content (r = 0.87), sorbitol content (r = 0.88), and chlorophyll A content (r = 0.97) of intact peaches and nectarines, and required no sample preparation.
