METHOD OF COMPLEX GIRASOL-SUNFLOWER PROCESSING Russian patent published in 2010 - IPC A23L1/214 

FIELD: food industry.

SUBSTANCE: girasol-sunflower is washed and milled. Then acid water is poured over girasol-sunflower for pH to be 5-6.5, the ratio of phases being 1:1 at preset process parametres. Girasol-sunflower undergoes treatment in a microwave field until inactivation of native enzymes. One proceeds with extraction at 55-65°C. Then follows consistent passing of the extract through membrane with retention threshold of 6.0-8.0 kilodaltons and 0.8-2.0 kilodaltons with return of low-molecular fraction on extraction phase. Then one performs concentration of the rest of the fractions through reverse osmosis. One combines concentrate of low-molecular fraction with extraction cake with gelatinising concentrate obtaining. The remaining concentrate which is actually an inuline-containing solution undergoes photosterilisation and packaging under aseptic conditions.

EFFECT: method enables integral girasol-sunflower processing with complete utilisation of nutrients and biologically active substances of the initial raw materials.
