SILICON-CONTAINING COMPOSITION OF RICE HUSKS AND ITS PRODUCTION METHOD Russian patent published in 2012 - IPC A23K1/00 A23K1/16 

FIELD: food industry.

SUBSTANCE: group of invention relates to silicon-containing compositions of rice husks that may be used in feeding stuff production. The formulation of the on-containing composition of rice husks is as follows, wt %: hydrolysing agent - 0.5-15, air-dry rice husks with water content up to 17 wt % - balance. In particular, the composition contains sodium hydroxide as a hydrolysing agent. Content of sodium hydroxide in this composition is preferably 3 wt %. In particular, the composition contains sodium carbonate as a hydrolysing agent. Content of sodium carbonate in this composition is preferably 6-15 wt %. This composition is produced by way of mechanochemical activation of a mixture of the hydrolysing agent and air-dry rice husks with water content up to 17 wt % taken at a ratio of (85÷100) : (0,5÷15) accordingly in a activator crusher ensuring grinding bodies acceleration equal to 80-250 m/s², time of maintenance within the treatment zone being 0.5-2.5 min. The activator crusher may be represented by flow ball vibro-centrifugal, ellipse, centrifugal or centrifugal roll crushers.

EFFECT: silicon-containing composition produced by this method possesses moderate antioxidant activity and is noted for increased content and improved bioavailability of water-soluble silicon dioxide present in rice husks which renders the fodder balanced in terms of silicon content.
