METHOD OF PRODUCTION OF DIETARY FIBRES Russian patent published in 2008 - IPC A23L1/308 A23L1/212 A23L1/20 

FIELD: food industry.

SUBSTANCE: invention refers to technology of practically indigestible dietary fibres. Method of production of dietary fibres provides raw material humidification to value 13-20%, impregnation of vegetative raw materials with liquid carbon dioxide and isolation of liquid carbon dioxide excess. Further depressurisation follows at rate providing freezing of carbon dioxide absorbed by raw materials. Then raw materials are heated up at rate providing sublimation of carbon dioxide, and then raw materials are extracted with dietary fibres isolation from extract.

EFFECT: provides reduction of dietary fibres losses.
