METHOD OF PRODUCING FRUCTOSE-GLUCOSE SYRUP FROM GIRASOL Russian patent published in 2016 - IPC C13K13/00 

FIELD: food industry.

SUBSTANCE: invention relates to food industry. Method of producing fructose-glucose syrup from girasol tubers involves washing and grinding girasol, extraction for 15-20 minutes, separation of extract from solid phase, concentration and packaging. After grinding juice is squeezed from washed fresh girasol. After separation of pomace from solid phase, hot water is gradually added at temperature 80-85 °C until obtaining water duty juice/water (1:1)-(1:2), pomace is placed in an ultrasonic bath with heating, sugar is poured with water and extraction is carried out at temperature 70-80 °C. Extract is separated from solid phase by filtration, squeezed in hot form, then filtrate is mixed with water-diluted juice. Method then includes hydrolysis thereof to obtain fructose-glucose syrup by adding a solution of edible citric acid to pH 3.0-4.0 at temperature 80-85 °C for 4-4.5 hours with constant stirring. Hydrolysate is concentrated in vacuum-evaporator at temperature 80-85 °C to content in fructose-glucose syrup not less than 85-90 % of dry substances, then ready syrup is packed into containers.

EFFECT: invention increases dry substances content in fructose-glucose syrup to 85-90% compared to prototype.
