Abstract: A method of producing a retinyl ester compound comprising subjecting a composition comprising retinyl or a retinyl ester and a fat or oil of animal or vegetable origins to enzyme catalysed trans-esterification in solvent free conditions to produce a retinyl ester.

Abstract: The invention concerns blends of a hydroquinone substituted poly unsaturated fatty acid (as present in Kombo nut oil) or a derivative thereof, which blends comprised: (i) 0.1-99.9 wt % of the substituted acid (ii) 0-99.8 wt % of Kombo butter glycerides (iii) 0.1-99.9 wt % of other triglycerides Food products and food supplements comprising such hydroquinone substituted acids are also part of the invention. The substituted acids display many useful health benefits.

Abstract: Immobilized lipases are prepared containing lipase bound to a dry, porous particulate hydrophobic support having an average pore size of 0.05-5 .mu.m. Preparation is carried out by contacting the hydrophobic support with an aqueous solution of the lipase and with a non-ionic surfactant containing at least one fatty acid and having an HLB-value of at least 8 to provide a supported lipase, washing the supported lipase and drying the washed supported lipase to obtain the immobilized lipase. The lipase may be obtained from Candida Antarctica .beta., Rhizomucor miehei,Humicolo or Candida Rosa, and be a lipase specific for esterification of fatty acids with alcohol, 1,3-specific or randomizing transesterification lipase or lipase specific for the hydrolysis of partial glycerides, esters or triglycerides. The surfactant may be present in the aqueous solution of lipase in a concentration of 0.01-10 wt. %, and preferred surfactants are a polyoxyethylene sorbitan fatty acid ester and a polyglycerol fatty acid ester.

Abstract: Esters in which the alcohol part is sterically hindered around the ester bond, i.e. derived from tertiary alcohols are enzymatically prepared under low water conditions using Candida antarctica lipase A or a lipase species having a substrate activity similar to that of Candida antarctica lipase A with respect to tertiary alcohol esters.
