Improvement of industrial technology for new varieties

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, based on the characterization of paddy rice grain, aims to Establish specific whitening technologies that ensure 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. For this research, new rice grain processing technologies were evaluated in 5 sowing campaigns, executed in fields of one hectare and harvested every 5 days, starting at 50% of flowering; giving us as results the optimal harvesting technologies, to guarantee the production potential of agricultural yield at 14% of humidity, total polished rice and whole white grain, adequate moment to carry out the harvesting.
