- Preparation of n-3 PUFAs ethyl esters by an efficient biocatalyzed solvent-free process
-
alpha-Linolenic acid (ALA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have been subjected to esterification with ethanol in presence of lipase B from Candida antarctica (Novozym 435), in solvent free condition. The use of alcohol donors triethyl orthoformate (TEOF) or diethyl carbonate (DEC) instead of free ethanol, allowed working in irreversible esterification conditions and ALA-, EPA- and DHA-ethyl esters were obtained in quantitative yields.

- Process for the preparation of a composition comprising unsaturated compounds
-
The present invention relates to a process for the preparation of a composition comprising unsaturated compounds, in particular polyunsaturated compounds, which comprises concentrating and purifying the compounds by contact with silicon and/or aluminium derivatives. The process of the invention represents an advantageous substitute of the usual distillation processes, coupled or not to chromatographic processes, and allows to isolate and remove polar byproducts.

- Characteristics of Lipase Modified with Water-soluble Acylating Reagents and Its Esterification Ability
-
Lip was modified with various hydrophobic groups, such as Z, Boc, lauroyl, and palmitoyl, using water-soluble acylating reagents.The chemical modification enhanced the dispersibility of Lip in organic solvents, and changed the substrate selectivity, which depends on the length of the carbon chain of triglycerides in hydrolytic reactions.As for the synthesis of triglycerides, Z-modified Lip catalyzed this reaction faster than unmodified Lip.Z-, Boc-, and fatty acid-modified Lips also catalyzed diverse esterification reactions including that of ethyl eicosapentaenoate, lactose oleate, and cholesterol oleate, and the yields of these reactions increased depending on the carbon number of the introducing group.
