Characterization of individual rice kernel moisture content and size distributions at harvest and during drying.

Moisture content (MC) and size distributions of individual kernels in a panicle were measured from rice cv. Bengal, Cypress, and Drew harvested at two locations (Rice Research and Extension Center, Stuttgart, and Northeast Research and Extension Center, Keiser) during autumn 1999 to obtain fundamental information for optimizing postharvest processes, specifically for drying and milling. Individual kernel MC distributions in a panicle were multi-modal, especially at high harvest MC (HMC), and were skewed at lower HMC. The standard deviation of kernels from a panicle decreased with decreasing MC. Individual kernel size for rough and brown rice were normally distributed and different for the three varieties tested. Kernel size distributions at various harvest MCs and during drying are discussed, as is the corresponding shrinkage in kernel size caused by drying.
