Title (EN) METHOD FOR THE PREPARATION OF FAT MIXTURES COMPRISING EICOSAPENTAENOATE ESTER FROM WORMS OF FAMILY LUMBRICIDAE AND, OPTIONALLY FATTY ACID MIXTURES COMPRISING EICOSAPENTAENOIC ACID THEREFROM
(FR) PROCEDE DE PREPARATION DE MELANGES GRAISSEUX COMPRENANT L'ESTER EICOSAPENTAENOATE PROVENANT DES VERS DE LA FAMILLE DES LUMBRICIDES ET EVENTUELLEMENT DES MELANGES D'ACIDES GRAS COMPRENANT DE L'ACIDE EICOSAPENTAENOPIQUE PROVENANT DE CEUX-CI
Abstract:
(EN) Water-washed worms are kept between wet paper sheets at 4 to 10 °C for 40 to 80 hours in order to clean them internally then treated with 0.1 to 1.5 per cent by weight of enzyme calculated for the dry weight of worms, for about 1 to 4 hours. The treated mass is dried in a conventional manner then extracted with a lipophilic solvent or with a supercritical fluid. The extract is separated from the residual solid and exempted from the solvent by a conventional method. Optionally, fatty acids are released from the fat compounds obtained in a conventional manner and the mixture is enriched in eicosapentaenoic acid by any known method.
(FR) On garde des vers de terre lavés dans de l'eau entre des feuilles de papier humides à une température comprise entre 4 et 10 °C pendant une durée comprise entre 40 et 80 heures afin de les laver à l'intérieur, puis on les traite avec entre 0,1 et 1,5 % en poids d'une enzyme calculée en fonction du poids à sec des vers, pendant une durée comprise entre 1 et 4 heures. La masse traitée est séchée de façon traditionnelle puis extraite à laide d'un solvant lipophile ou d'un fluide surcritique. On sépare l'extrait du solide résiduel puis on en retire le solvant au moyen d'un procédé traditionnel. On peut éventuellement libérer des acides gras des composés graisseux obtenus de manière traditionnelle, et enrichir le mélange dans de l'acide éicosapentaénoïque au moyen d'un procédé connu.
