Abstract. In order to improve the consumer, organoleptic and technological properties of waste from the processing of plant raw materials, bleaching methods have been developed that allow for significant lightening of plant fibers. The efficiency of bleaching rapeseed fibers using hydrogen peroxide has been assessed visually. During the study, rational parameters of the bleaching process have been established: substrate concentration of 10 %, mass fraction of peroxide of 6 %, temperature of 80 °C, processing time of 6 hours. Rapeseed dietary fiber dried in a freeze-drying unit has higher values of moisture-binding (8.27 g water/g PV) and fat-binding (4.35 g oil/g PV) capacity (by 32 and 23 %, respectively) compared to rapeseed dietary fiber dried in a drying cabinet. Rapeseed dietary fiber dried in a freeze-drying unit is not inferior in moisture- and fat-binding capacity to a commercial soybean preparation (Amursky MEZ). Analysis of the chemical composition of the obtained rapeseed fibers has shown that they contain less crude protein than soybean fibers (by 60 %), and more crude protein than wheat fibers (by 90 %). Further research can be devoted to studying the effect of rapeseed fibers on the functional, technological, rheological and organoleptic properties of food products. The method for obtaining rapeseed dietary fiber based on solid protein extraction waste has great potential in organizing production on an industrial scale, allowing enterprises to carry out valorization of rapeseed processing products.
