Near-infrared prediction of functional characteristics of milled rice.

Three rice cultivars harvested in 1996 and 1997 in Arkansas were subjected to different drying and storage conditions. Subsamples were periodically removed, hulled, milled, scanned, and analysed for functional characteristics (cooking and pasting properties). All samples were scanned for near-infrared (NIR) reflectance (400-2500 nm), and multivariate calibrations were developed. For volume expansion, water absorption, peak viscosity, and final viscosity, the standard errors of prediction for the NIR calibrations were 0.20, 0.16, 61 Brabender Units (BU), and 83 BU, respectively, with R2 ranging from 0.28 to 0.61 in the calibration models. The results indicate that it might be feasible to use NIR technology for rapid screening of functional properties influenced by postharvest handling.
