Abstract: A process for the isolation of lipid fractions from egg products in powder form with a content of phospholipids is described in which the egg product is extracteda) with liquid propane at a pressure of .ltoreq.200 bar and a temperature of .ltoreq.70.degree. C. andb) an entraining agent consisting of an aliphatic alcohol with 1 to 4 C atoms.In this way it is possible to produce lipid fractions with good sensory properties whose content of phospholipids is at least 20% by weight.

Abstract: The invention relates to a process for recovering monoglycerides and optionally diglycerides and/or triglycerides as well as optionally glycerol from mixtures comprising glycerides and glycerol containing glycerides, respectively, by countercurrent extraction with a circulating extraction. As an extractant, forming a separate phase, there is used a hydrocarbon having a density of more than 180 kg/m.sup.3 and/or trifluoromethane having a density of more than 180 kg/m.sup.3.

Abstract: Triglycerides, such as vegetable oils and animal fats, are esterified with alcohols to produce alcohol esters which can be used as alternative fuel sources. By-products of the transesterification reaction are stripped from the effluent of the transesterification reactor using a recovery alcohol that can be an isolated by-product of the transesterification reaction.

Abstract: This invention relates to a purified wool fat essentially free from low molecular weight volatile acids, water soluble aliphatic alcohols and water. This purified wool fat is produced by effecting the esterification of free alcohols and fatty acid contained in the wool fat followed by solvent extraction and chromatographical purification of the extracted solvent. The purified wool fat can be used as a lubricant enhancer in lubricating oils.

Abstract: A method for recovering at least one unsaturated fatty acid having sixteen or more carbon atoms and/or at least one compound of such a fatty acid from a mixture derived from vegetable, animal or marine sources is provided. Fatty acids and/or fatty acid compounds of the mixture, in free acid or esterified form, are passed into a mobile phase of liquid carbon dioxide in a column over a stationary phase. The stationary phase contains a support and a material bound to the support which contains at least one free electron pair and/or multiple bond. After eluting any saturated fatty acid or fatty acid compound of the same number of carbon atoms from the column, the unsaturated fatty acid and/or fatty acid compound is recovered in pure chemical form or as an enriched mixture.

Abstract: In a process for the production of tertiary carboxylic acids, especially by "Koch synthesis", the byproducts, e.g., a dimer of tripropene, are removed from the reaction mixture by azeotropic rectification with alkanediols, e.g., 1,3-butanediol, as entrainers, thus obtaining the tertiary carboxylic acids in pure form.

Abstract: Impurities, which may include soaps, gums, phospholipids and pigments, can be removed from chemically or physically refined glyceride oils in a dual phase adsorption and treatment process. In the first phase, the oil is contacted with amorphous silica to remove phospholipids and soaps or gums or both. In the second phase, the oil is passed through a packed bed of a pigment removal agent for decolorizing glyceride oils.

Abstract: A process of refining mixtures obtained from treatments of fatty media with cyclodextrin and containing complexes of cyclodextrin with lipophilic compounds, characterized by the fact that the said mixtures are washed with at least one anhydrous polar solvent, whereby at least partial dissociation of the complexes of cyclodextrin/lipophilic compounds is brought about, and the lipophilic compounds which are not included are released from their connection with cyclodextrin.

Abstract: Process of refining mixtures obtained from treatments of fatty media with cyclodextrin and containing complexes of cyclodextrin with lipophilic compounds of the fatty acid type, characterised by the fact that the said mixtures are subjected to a heat treatment at a temperature above 100.degree. C. in the presence of a solvent system containing water, that the various fractions or raffinates obtained from the heat treatment are separated and that these raffinates are recovered.

Abstract: A process for the extraction of eicosapentaenoic (EPA) and docosahexaenoic (DHA) acid esters from crude fish oils, by means of transesterification with ethanol and H.sub.2 SO.sub.4 and two-step molecular distillation.

Abstract: Generally in accordance with the present invention, methods are provided for removing cholesterol from edible triglyceride oils. In this regard, animal fats typically contain cholesterol predominantly in the form of free cholesterol, as well as minor amounts of cholesterol esters of fatty acids such as cholesteryl oleate or palmitate. The present methods may be used to remove cholesterol from both animal and vegetable triglyceride oils, including, but not limited to, butterfat, beef tallow, fish oil, lard, soybean oil, canola oil, corn oil, sunflower oil, cottonseed oil, safflower oil, olive oil and peanut oil.

Abstract: Countercurrent liquid/liquid extraction processse for fractionating complex triglyceride mixtures to selectively remove "light" impurities (primarily MMM trglycerides) from MML/MLM triglycerides, or to selectively remove MML/MLM triglycerides from "heavy" impurities (primarily MLL/LML and LLL triglycerides), wherein M is a C.sub.6 -C.sub.10 fatty acid residue or mixture thereof, and wherein L is a C.sub.18 -C.sub.24 fatty acid residue or mixture thereof, are disclosed. In the case of "light" impurities, an oil stream containing MMM and MML/MLM triglycerides is passed countercurrently to a solvent stream containing a polar solvent or a supercritical fluid that is partially miscible with the oil stream to selectively remove the MMM triglycerides. In the case of "heavy" impurities, an oil stream containing MML/MLM, MLL/LML and LLL triglycerides is passed countercurrently to the solvent stream to selectively remove the MML/MLM triglycerides.
