DESCRIZIONE
The invention relates to a protein preparation produced from rape seeds having a protein content of less than 90 % in relation to the dry mass having a brightness L*, determined according to CIE-L*a*b* colour scale, of at least 70 and also having at least water-binding, oil-binding and emulsifying functions. Said method for producing a protein preparation consists of dehulling the rape seeds and subjecting them to a mechanical deoiling process wherein only one part of the oil is separated and/or the deoiling is carried out at a temperature of less than 80°C which is determined according to the duration of the pressing process, and/or subjecting the grains to an extraction process wherein the amount of non-protein material is reduced in the protein flour and then the grain size is prepared in order to obtain bulk material having a predetermined particle size distribution.
