In Cuba, rice production manifests considerable economic losses that are caused by delays in harvest and post-harvest, due to the reduction in yields of total polished rice and whole white grain during industrial processing, without the application of adequate technology. The present work was carried out at the Grain Research Institute, to establish specific milling technologies that guarantee maximum utilization of the whole white grain during the milling process of rice varieties released by breeders for introduction at the final stage of the production chain.
