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