Abstract
Near‐infrared (NIR) reflectance spectroscopy was used to develop calibration equations to measure chemical composition (dry matter, crude protein and reducing sugars) in carob samples. Calibration equations were obtained by multiple linear regression of conventional laboratory analysis values on NIR spectra from 75 samples and verified with 20 additional samples from the original population, collected on the Spanish Mediterranean littoral in different years. A Tecnichon Infra Alyzer model 450 monochromator interfaced with an IBM PS2 microcomputer was used for the study. Two alternative calibrations were chosen using three and six wavelengths. The coefficients of multiple correlation ranged from 0·91 to 0·95 and the standard errors of calibration ranged from 0·38 to 1·62. The study showed that NIR analysis can be used for predicting the chemical composition of carob pulp. Copyright © 1993 John Wiley & Sons, Ltd
