20090186861 | Process for Production of Fatty Acids, Fatty Acid Esters and Sterolesters from Soapstock - The invention relates to a process for production of fatty acids directly from soapstock generated in the alkali refining process including the steps of (a) adding a lipase directly to the alkaline soapstock to facilitate hydrolysis of glycerides without prior neutralisation, (b) neutralizing and splitting the soaps with strong acids, and (c) separating the fatty acid phase from the aqueous phase by settling and/or centrifugation. A second embodiment is a process in which the soapstock is first neutralized and split with strong acids, followed by adding a lipase to facilitate glyceride hydrolysis, and separating the fatty acid phase. The fatty acids so obtained can be esterified with C1-C6 alcohols using a lipase that is selective for fatty acids and does not transesterify the sterolesters, and the fatty acid esters and sterolesters are separated by distillation. | 07-23-2009 |
20110089370 | Lipophilic Preparations - Disclosed are novel lipophilic preparations comprising (a) from 20 to 40% by weight of myristic acid or esters thereof, (b) from 20 to 40% by weight of palmitic acid or esters thereof, (c) from 0.1 to 5% by weight of aliphatic and/or cycloaliphatic hydrocarbons and (d) less than 20% by weight of carboxylic acids or esters thereof having 12 and fewer carbons in the acyl moiety and (e) less than 20% by weight of carboxylic acids or esters thereof having 16 and more carbons in the acyl moiety, with the proviso that all percentages add up to 100% by weight. | 04-21-2011 |
20140170717 | Ester Synthesis - The present invention relates to a process for preparing esters from fatty alcohols, in which fatty alcohols and fatty acids are reacted in the presence of an enzyme at a temperature in the range of 30 to 50° C., the water which forms is removed and the reaction is completed under reduced pressure at a temperature of 50 to 80° C. | 06-19-2014 |
