METHOD FOR PRODUCTION OF INSTANT PRODUCT OF SUGAR BEET PULP Russian patent published in 2015 - IPC A23L2/00 

FIELD: food industry.

SUBSTANCE: dry pre-granulated sugar beet pulp is soaked in 0.7% solution of hydrochloric acid, maintained in a closed vessel for 28-30 days at a temperature of 38-40°C, fermented and treated in an electromagnetic field with flux density equal to 0.5 tesla and voltage equal to 450-500 V/m and imposed modulation equal to 100 kHz ± 25 kHz during 2.5-3 min with further periods of rest equal to 10 min in the course of 60-72 h, the ambient temperature equal to 24-27°C and relative air humidity equal to 96-98%. After fermentation, one carries out a process of promotorisation with the help of an electrical field with nanosecond duration pulses, the amplitude of output pulse voltage equal to 18 kV, pulse duration - 7 nsec, pulses succession frequency - 800 mHz, treatment time - 8 sec with further 4 min period of rest in the course of 30 min; one performs water extraction at a ratio of 1:1 with temperature increase to the point of boiling and boiling during 30 min with stirring, expression, filtration, spray drying and granulation.

EFFECT: production method results in high preservation of biologically active substances and thus to improvement of the ready product quality.
