FIELD: agriculture.
SUBSTANCE: method involves extraction of root mass of licorice, selection of root mass and formation of piles, loading the piles into vehicles and delivery to primary processing places. The root mass is cut into pieces of length 0.10-0.30 m. The cut root mass is saturated with magnesium chloride from brine of the naturally occurring bischfite mineral. Later a carpet is made from the root mass on steel sheets. A bonding material is then deposited on the root mass carpet. Before pressing, the sheets are piled with the packed cut root mass to a given height at the bottom of a plate holder. The packets of sheets with the root mass carpets are pressed. Between the steel sheets in the plate holder, the carpets are kept in the pressed state for 6-8 hours at temperature above 20°C. The plate holder is then dismantled, and the root mass pressed into sheets is then conditioned. A pile is formed under the size of piles of the sheets cut into a roll. The formed pile from sheets cut along the perimeter is packed into a moisture-proof film and tied up by metallic bands with buckles.
EFFECT: retention in the licorice raw material of flavonoids and glycyrrhiza acid during long term storage of licorice in piles.
