Title (EN) METHOD FOR PRODUCING CONJUGATED LINOLEIC ACID
(FR) PROCÉDÉ DE PRODUCTION D'ACIDE LINOLÉIQUE CONJUGUÉ
Abstract: front page image
(EN)A method for producing a composition comprising conjugated linoleic acid in an amount of at least 55 % by weight, comprises: (i) providing a liquid mixture comprising, as the free acids, from 50 to 95 % by weight conjugated linoleic acid and at least 5 % by weight of saturated C12- C22 fatty acids; (ii) cooling the liquid mixture to a temperature at which at least a part of the saturated C12-C22 fatty acids precipitate from the mixture as a solid; and (iii) separating the solid from the liquid, wherein the liquid obtained in (iii) comprises conjugated linoleic acid in an amount of at least 55 % by weight.
(FR)La présente invention concerne un procédé de production d'une composition comprenant de l'acide linoléique conjugué en quantité d'au moins 55 % en poids, consistant à : (i) fournir un mélange liquide comprenant, comme acides libres, de 50 à 95 % en poids d'acide linoléique conjugué et au moins 5 % en poids d'acides gras saturés en C12- C22 ; (ii) refroidir le mélange liquide à une température à laquelle au moins une partie des acides gras saturés en C12-C22 précipitent à partir du mélange sous forme d'un solide ; et (iii) séparer le solide du liquide, le liquide obtenu en (iii) comprenant de l'acide linoléique conjugué en quantité d'au moins 55 % en poids.
