FIELD: food industry.
SUBSTANCE: invention relates to food industry and can be used for manufacturing dietary fibres. The method of manufacturing dietary fibres implies hydrolysis of raw material under the temperature of 50-70°C during 2 hours with following 15-minutes inactivation. Hydrolysis is carried out by pectintranseliminase Bacillus subtilis with the activity of 32380.0 units/ml or α-amylase Bacillus licheniformis with the activity of 633.3 units/ml. Hydrolysis can also be carried out by complex enzyme preparation of Bacillus subtilis or Pemcillium emersonii cultures with the proteolytic activity of 490.0 units/ml and amylase activity of 458.7 units/ml or complex enzyme preparation Aspergillus specium with endopolygal acturonase activity of 812.4 units/ml, proteolytic activity 480.8 units/ml and amylase activity of 468.3 units/ml. The obtained dietary fibres are separated and decolourised by hydrogen peroxide solution.
EFFECT: producing dietary fibres with maximum output.
