METHOD OF PREPARING INULIN-CONTAINING SOLUTION Russian patent published in 2011 - IPC C08B37/18 

FIELD: chemistry.

SUBSTANCE: invention relates to a technique for preparing an inulin-containing solution for food or medical purposes. Dandelion root is washed, crushed and extracted with acid water in phase ratio of 1:1.2, pH 5-6.5 and periodic pressure release in the extraction mixture before the extraction agent boils. The extracted mixture undergoes preliminary electrocontact heating to temperature 55-65°C. The separated extract is concentrated through reverse osmosis to 15-20% content of dry substances, subjected to photosterilisation and packed under aseptic conditions.

EFFECT: invention reduces chromaticity of the end product with relatively high conversion of inulin to the end product, reduces energy consumption and ensures shelf life of the end product of not less than 1 year without considerable change of its consumer and technological properties.
