摘要：
The invention relates to the food industry. A method for processing sunflower or rapeseed meal includes, according to a first variant, extracting protein and carbohydrates from the meal by means of introducing an aqueous alkali solution having a pH of 8.5-9.5 into a suspension prepared from a mixture of meal and water in a ratio of 1:5-10, and keeping the suspension at 45-55°С for a period of 45-60 minutes. The suspension is fed to a decanter, producing an extract and a solid phase (cake, low protein fiber) to be subsequently dried and granulated. The extract is purified, producing purified extract and a solid state (sludge) to be subsequently dried and granulated. Protein is extracted by means of ultrafiltration, concentrated by means of evaporation at low temperatures, and subsequently dried, producing a concentrate of sunflower or rapeseed protein. Carbohydrates which have passed through the ultrafiltration apparatus are extracted using a reverse osmosis filtration apparatus, forming a saccharide solution and concentrating the carbohydrates to produce saccharide syrup. The method according to a second variant is characterized in that the extract produced after the first decanter is mixed with water and fed to a second decanter, forming a solid phase and an extract. Then the extract produced by means of mixing the extracts after the first and second decanters is purified, producing a solid phase (sludge) and purified extract. The resultant sludge is mixed with the solid phase (cake, low protein fiber) after the second decanter, for the subsequent drying and granulation thereof.Linvention se rapporte au domaine de lindustrie alimentaire et concerne un procédé de transformation de tourteaux de tournesol ou de colza qui, selon une première variante, consiste à séparer les protéines et les hydrates de carbone des tourteaux en ajoutant dans une suspension, obtenue par un mélange de granulés et deau selon un rapport de 1 :5-10, une solution aqueuse dalkali jusquà attein
