METHOD FOR PRODUCING DRY SOLUBLE CHICORY EXTRACT Russian patent published in 2021 - IPC A23F5/44 

FIELD: food industry.

SUBSTANCE: prepared chicory roots are fried at a temperature of 170-220ºC. The roots wet grinding is carried out with a duty of water from 1:8 to 1:20 at a temperature from 25 to 85ºC, a pH level from 3.5 to 6.5 and using a cavitation-type dispersant to a particle size of no more than 75 mcm. Enzymatic hydrolysis of the crushed raw materials is carried out for 1-8 hours with the use of a complex of enzymatic preparations containing cellulose and hemicellulosolytic enzymes. The extract is extracted and filtered on a reel vacuum filter. Separation and concentration is carried out on a membrane vacuum evaporation unit until 37-52% of the dry substance is obtained for subsequent drying on a spray-drying unit at an air temperature not exceeding 170ºC to obtain the final product with a dry substance extractivity of 20-28%.

EFFECT: invention provides an increase in the extractivity of dry soluble chicory extract to 28%.
