Bottega, G., Caramanico, R., Lucisano, M., Mariotti, M., Franzetti, L., Pagani M.A. (2009).The debranning of common wheat (Triticum aestivum L.) with innovative abrasive rolls.Journal Food Engeneering, in press.The physical and chemical modifications associated with the debranning of common wheat (Triticum aestivumL.) and the improvement of the hygienic characteristics of the kernels were examined. A pilot-plant debranningmachine was equipped with rolls lined with synthetic diamond powder, an innovative abrasive material. Thetechnological parameters taken into account were: the particle size of the abrasive elements, the processing time,the number of debranning passages and the hydration conditions of the kernels before treatment. The abrasive effectswere observed by Scanning Electron Microscopy and quantified by evaluating the debranning level andseveral chemical and physical indices of kernels and waste. A preliminary hydration passage was determinant forreducing kernel breakage during debranning. Best results in terms of homogeneous removal of bran layers wereobtained with the addition of 3% water and keeping the hydrated mass mixing for 5 minutes. Abrasive surfaceswith fine particle size (
