Latest Patents

Ya-Dong Liu holds a patent for a method of commercial preparation of conjugated linoleic acid. This patent details methods for simultaneous saponification and quantitative isomerization of glyceride oils containing interrupted double bond systems. The process involves using alkali in water to yield soaps with conjugated double bond systems. The patent also discloses novel methods of hydrolysis of the soap product with acid to form fatty acid-water emulsions and the breaking of those emulsions. The preferred embodiment utilizes vegetable oils rich in linoleic acid, such as sunflower or safflower oil, along with potassium hydroxide and phosphoric acid to neutralize the soaps. An emulsion breaking compound, which may include ethanol or other monohydric alcohols, tannins, or polyethylene glycol, is also part of the process. The reaction produces positional and geometric isomers of conjugated linoleic acid, with the preferred isomer mixture controlled by agitation, heating, and rapid initiation and termination of the reaction. The composition of the reaction product may be enriched through crystallization.
