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

FIELD: food industry.

SUBSTANCE: girasol is washed, ground, poured with acidified water and treated in microwave field until native ferments are inactivated. Extracted at the specified parametres of the process. Then serially passed through membranes with retention threshold of 6-8 kDa and 0.8-2 kDa with return of low molecular fraction to extraction stage. Remaining fractions are concentrated with reverse osmosis until dry substances content is at least 15%. Concentrate of high molecular fraction, containing protein and pectin substances, is combined with extraction cake to make gelling concentrate, remaining concentrate is photosterilised and packed under aseptic conditions, and this concentrate is inulin-containing solution purified from attendant substances.

EFFECT: method makes it possible to eliminate losses of protein, pectin, polyphenol and low molecular biologically active and nutrient substances preserved in composition of gelling concentrate.
