METHOD FOR COMPLEX PROCESSING OF CONCENTRATED UNCLARIFIED AND CLARIFIED GIRASOL JUICE Russian patent published in 2012 - IPC A23L2/02 

FIELD: food industry.

SUBSTANCE: invention relates to food and processing industry, in particular, to methods for girasol tubers processing. The method for processing concentrated unclarified and clarified girasol juices envisages the concentrate dilution with hot water with a temperature of 50-90°C till dry soluble substances content is 17 wt %. The produced inulin-containing solution is delivered to the ultrafiltration device with polymer membranes sized 8 and 5 kDa. The produced retentate is concentrated, inulin is extracted from the produced solution by way of crystallisation at a temperature of 5-10°C; glucose-fructose syrups are produced by fermentative method. The fructooligosaccharides-containing permeate produced after filtration with separation threshold equal to 5 kDa is concentrated till dry soluble substances content is less than 75 wt % for syrup production or is delivered for spray drying.

EFFECT: invention allows to simplify the process of production of inulin, fructooligosaccharides, glucose-fructose syrups due to processing concentrated unclarified juices semi-products and preserve quality indices of the end products.
