Near infrared transmittance (NIT) spectroscopy was examined as a means for measuring raisin quality. High positive correlation was found between measured values and those predicted by NIT for bulk density, visual grade, and moisture content. NIT measures properties at the molecular level. Thus, results showed a relationship between raisin quality and some chemical constituents. NIT analysis has the potential for measuring general raisin quality as well as specific constituents.
