Disclosed is a process for the fractionation of wool wax acid mixtures by dissolving the starting material in a polar organic solvent (mixture). The dissolved wool wax acid mixture is treated at a temperature between -5 and 30.degree. C. and at a pressure between 10 and 70 bar with gaseous carbon dioxide and the hydroxy-fatty acids that accumulate as a solid are separated from the solution.

For the extraction of carotenes, in particular of .beta.-carotene, from natural sources, these are stirred for several hours at at least 30.degree. C. in a solvent mixture composed of acetic esters of C.sub.1 -C.sub.4 alcohols as well as a portion of 1 to 25% by weight of an oil of biological origin. The natural colorant is in this way obtained in very high space-time yields and high purity.

A process is described for the purification of carbohydrate derivatives with surface-active properties in which an extraction process is used to liberate the solid or liquid starting material from undesired lipophilic by-products by the use of compressed propane or a proportionate mixture thereof with butane at pressures between 8 and 150 bar and a process temperature below 120.degree. C. In this way it is possible to isolate valuable raw materials in a gentle manner either batch-wise or continuously which meet the high purity requirements, for example in the field of cosmetics.

A process is described for the production of egg-based products in powder form with a reduced fat and cholesterol content in which the starting material in powder form is extracted with liquid propane at a pressure of .ltoreq.200 bar and at a temperature of .ltoreq.70.degree. C. In this way low-cholesterol and low-fat egg powder products with good sensory properties are produced without the phospholipids and in particular lecithin being removed to a substantial extent in this process.

The present invention provides a process for the production of fat- and cholesterol-reduced powdered products based on eggs with a high content of phospholipids by extraction with compressed gases, wherein the powdered starting material is extracted with a solvent mixture consisting of propane and carbon dioxide with a mixing ratio of 95/5 to 5/95% by weight at a pressure of &lt;300 bar and at s temperature of &lt;70.degree. C.,

The present invention provides a process for the production of highly concentrated fruit aromas from condensed fruit vapours, wherein a) the fruit aromas in the fruit vapours are concentrated to a content of 0.05 to 1% by weight according to known methods, b) the concentrate from step a) is subjected to an extraction with compressed carbon dioxide at 60 to 180 bar and 10.degree. to 50.degree. C., and c) after decompression of the carbon dioxide and optionally after the addition of water, the aromarich oily phase is separated from the aroma-poor aqueous phase.

In a process for the removal of cholesterol and cholesterol esters from egg yolk, the egg yolk is diluted with an aqueous solution of a water-soluble salt of the cation potassium or/and calcium as well as the anion chloride and/or sulfate or/and an organic anion with a molecular weight of .ltoreq.150. The diluted egg yolk is subsequently mixed with .beta.-cyclodextrin until complexation of cholesterol and cholesterol esters with .beta.-cyclodextrin has taken place. The formed complexes are separated and after separation of the complexes from the egg yolk mixture the added salt as well as, if desired, water is removed again. Low sodium egg yolk products with a low total cholesterol content and good sensorial properties are obtained.

A process for the extraction of fats and oils from natural substances using liquid propane as the solvent is described in which the extraction is carried out at a pressure of 10 to 30 bar and a temperature of 10.degree. to 55.degree. C. and the separation of the extracted fats and oils from the solvent is carried out by means of pressure reduction or/and temperature increase to .ltoreq.80.degree. C. High quality products are isolated in this way in a good yield and under mild conditions.

In order to stabilize hop products by drying at a circulating air temperature of 60.degree. to 80.degree. C. to a residual moisture content of the dried hop products of between 12 and 14% by weight, the hop product is subjected after drying to a short period of thermal irradiation or to a temperature treatment at 60.degree. to 90.degree. C. under inert gas conditions.
