Abstract
A high intensity computer controlled spectrophotometer was used to obtain near infrared (700 to 1 100 nm) speciral transmittance data of intact samples of onions, cantaloupes and potatoes. The dry matter was determined by freeze drying and the soluble solids by refractometer. A data reduction program computed the ratio of two second derivatives, opümizing 5 parameters of the computation. Linear correlations were above 0.99 for onions.
