Method for complex processing of concentrated unclarified and clarified girasol juice. RU patent 2444915.

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.

Method for production of concentrated unclarified and clarified girasol juice / 2444914
Invention relates to food, pharmaceutical, biochemical and processing industry, in particular, to methods for production of a girasol semi-product for subsequent processing. The method envisages washing and preliminary milling of raw material. The produced pulp is heated up to 100°C during 30-60 sec. and pressed. The refuses produced after pressing are treated with hot water with a temperature of 80-90°C, the mixture water duty being 1:2-3. An enzyme is added to the produced solution and has cellulasic and hemicellulasic activity. The produced juice is combined with that of primary pressing. Then the mixture is momentarily heated up to a temperature of 100°C and treated with bentonite and activated carbon (continuously stirred) during 30 minutes. Then the mixture is delivered for subsequent rough filtration. The produced juice is concentrated till dry soluble substances content is no less than 65 wt % to produce concentrated unclarified girasol juice. The produced unclarified concentrate with pulp content no more than 3 wt % is stored either pasteurised in aseptic vessels or unpasteurised in vessels cooled down to a temperature no higher than 10°C. For production of concentrated clarified girasol juice after rough filtration the juice is delivered for ultrafiltration through polymer membranes sized 8 kDa, the produced permeate is concentrated till dry soluble substances content is less than 70 wt %. The produced clarified concentrate is stored either pasteurised in aseptic vessels or unpasteurised in vessels cooled down to a temperature no higher than 10°C.
