<p>PURPOSE:To effectively remove lipid without eliminating a large amount of raw material rice for brewing by mechanical rice cleaning by subjecting raw material rice for brewing as it is or after any process of rice polishing, cleaning, immersing or steaming to specific extracting operation. CONSTITUTION:Raw material rice for brewing as it is or after any process of rice polishing, cleaning, immersing or steaming is brought into contact with carbon dioxide in a liquid or supercritical state and extracted so that saccharide attached to the surface of the raw material rice in rice polishing are removed and extraction efficiency of lipid is improved with carbon dioxide. The cleaning and immersing operations are preferably carried out by using water processed with an alkali or an acid and the extracting operation is done by bringing carbon dioxide in an upward countercurrent into contact with the raw material rice for brewing packed into a container.</p> |
