METHOD FOR PREPARATION OF CALCIUM-CONTAINING COMPOSITION FROM SEA URCHINS SHELLS Russian patent published in 2017 - IPC A61K35/616 

FIELD: medicine.

SUBSTANCE: flat sea urchin Scaphechinus mirabilis shell - the waste of echinochrome A production and/or shell and needles of the fishing sea urchin Strongylocentrotus nudus - the waste of spinochromes A and E production are used as the raw material. The raw material is demineralized by concentrated phosphoric acid followed by addition of distilled water to produce dibasic calcium phosphate, which is then washed three times in 96% ethanol until complete discoloration. The alcoholic extract is separated by filtration and the desired product is dried at a temperature not higher than 50°C. The composition includes, by weight. %: 50.00-55.00 of dibasic calcium phosphate; 31.0-33.0 of protein; 9.0-10.0 of monosaccharides; 1.09-1.12 of macroelements (Fe, K, Mg, Na); 0.002-0.003 of microelements (Cr, Mn, Co, Ni, Cu, Zn); the rest is water.

EFFECT: invention provides sea urchins processing waste recycling to provide a calcium-containing product.
