| titleOfInvention | Method for obtaining concentrate of unsaturated alkyl-glycerine ethers from sea hydrobionts |
| abstract | FIELD: food industry; pharmaceutical industry. n SUBSTANCE: invention relates to the food and pharmaceutical industry, in particular to a process for the production of alkyl-glycerol esters (AGE) from marine fats. Method consists in that sea fats containing the AGE in their composition are subjected to hydrolysis to recover free fatty acids and release the unsaponifiable fraction, the mixture is neutralized with acid and crystallized from acetone to obtain a precipitate of saturated AGE, the remaining lipid mixture is evaporated, further, by chromatography on a column of silica gel and an eluting system of organic solvents, with increasing polarity, a total fraction of alkyl-glycerol esters is isolated, the solvent is evaporated, the mixture is dissolved in a non-polar organic solvent to a concentration of 0.5 to 2 % of alkyl glycerol esters and mixed with solutions of silver nitrate in 20–60 % aqueous ethanol with a non-polar:polar = 1:1–2.8, ratio, and the ratio of unsaturated alkyl-glycerols: AgNO 3 = 1:3–7, mol/mol, stirred, centrifuged, the lower aqueous-ethanol layer separated, acidified with hydrochloric acid to precipitate the silver salt, filter the solution and evaporate the solvent to isolate the unsaturated alkyl-glycerol esters. Above described method takes into account the processes of interaction of silver salts with unsaturated organic compounds and allows using the advantages of this fact in the development of a simple technology for the concentration of unsaturated alkyl-glycerol esters. n EFFECT: method is effective and economical for the production of unsaturated alkyl-glycerol esters from marine fats, providing not only high quality of the target product, but also the integrated use of valuable marine raw materials. n 4 cl, 2 dwg, 1 tbl |
