摘要：
FIELD: food industry.SUBSTANCE: one mixes moist apple refuses with initial moisture content equal to 70% and pectin substances content equal to 15-30% with alkaline solution (KOH) with pH value equal to 7-9 which is prepared using softened water, water duty in terms of absolute dry substances being 1:25-1:30, at a temperature of 40-45°C in the vessel with a steam water jacket and a stirrer with perforated blades. One performs controlled gradual heating to 50-55°C, fluidjet addition of hydrogen peroxide solution (under continuous stirring conditions) till the temperature is equal to 50-55°C, at the stirrer rotation rate equal to 30-40 rpm till hydrogen peroxide concentration in the solution is equal to 0.5-0.75%. One proceeds with controlled gradual heating to 60-65°C. Bleaching is performed during 40-60 minutes from the moment when the temperature in the alkaline solution is equal to 65°C at pH value equal to 7-9 and at a temperature no more than 75°C. Squeezing is performed in a press-filter or centrifuge. One performs washing in a solution containing softened water and citric or acetic acid at a temperature of 40-45°C, pH value being 3.5-4.0. One proceeds with squeezing, infrared convective drying till moisture content is equal to 7-8% at a temperature no more than 35°C during the whole period of drying. Milling is performed to the required fraction size.EFFECT: method allows to obtain a paste-like product with high pectin and vegetal fibres content and colour from white to light-yellow.2 clИзобретение относится к способу отбелки пищевых растительных волокон, полученных из отходов сокопроизводства, в частности яблочных выжимок. Смешивают сырые яблочные выжимки с исходной влажностью от 70%, с содержанием пектиновых веществ 15-30%, с щелочным раствором КОН, при рН 7-9, приготовленным на умягченной воде при соблюдении гидромодуля по абсолютно сухому веществу 1:25-1:30, при температуре 40-45°C в емкости с пароводяной рубашкой и мешалкой с перфорированными лопастями.
