    • A process for preparing diglycerol in high concentrations and high yields by partially reacting glycerol in the presence of an alkaline catalyst to form a reaction mixture containing from 10 to 15% by weight of diglycerol and separating the unreacted glycerol from the reaction mixture in a wiped film or short path first distillation zone at a reduced pressure of 0.5 to 5 mbar and distilling a bottoms product from the first distillation zone in a second distillation zone which is a short path distillation zone at a pressure of 0.05 to 0.3 mbar to obtain a second bottom product containing at least 90% by weight diglycerol. Diglycerol of higher purity can be obtained by recovering diglycerol as a distillate from a third distillation zone.

    • A process is provided for simultaneously recovering tocopherol and sterol from a mixture containing tocopherol, fats and/or fat derivatives, more particularly fatty acids, and sterol and/or sterol derivatives, more particularly from a steamer distillate of natural oils and fats. The steps of said process comprise:free fatty acids present in the mixture are esterified with a lower alcohol, preferably methanol, 0.4 to 1.6 and more particularly 1 to 1.5 parts by volume of mixture being esterified with 1 part by volume of the lower alcohol,the mixture is subsequently transesterified with the lower alcohol in the presence of a basic catalyst,the excess lower alcohol is distilled off from the reaction mixture after the transesterification,the transesterification catalyst and the glycerol optionally present are removed, more particularly by washing,the fatty acid alkyl ester is distilled off from the mixture, more particularly after removal of the transesterification catalyst, andif desired, tocopherol and sterol are separated by methods known per se. After the transesterification reaction, the alkali catalyst is preferably neutralized with an inorganic acid and the mixture is then washed with water.

    • Carotene is recovered from a native fat or oil in five process steps in an economical industrial process. The native fat or oil is catalytically reacted in known manner with an alkanol containing up to 4 carbon atoms to form fatty acid alkyl ester and glycerol. The ester phase of the reaction mixture is subjected to distillation to remove the fatty acid alkyl ester. The distillation residue obtained in the second process step is saponified, carotene is extracted from the product obtained in the third process step and the extract phase is concentrated by evaporation. A yield of at least about 80% is achieved. At the same time, a fatty acid alkyl ester suitable for further processing to fatty alcohol is provided.
