FIELD: food products.

SUBSTANCE: mallows are sequentially extracted by non-polar liquified gas and drinking water with obtaining of corresponding extracts. Tea production refuses are mixed with fluid carbon dioxide, they are extracted and minced along with periodic depressurisation of extraction mixture below carbon dioxide vapour pressure at extraction temperature. Miscella and extraction cake are separated. The latter is dissolved in water solution of edible acid. Calciferous or magnesium salt of carbonic acid and water extract of common centauries is added to suspension. Then it is formed, dried till residual humidity 13-15%, cut, impregnated with gas-liquid extract of mallows and previously separated miscella with simultaneous pressure boost.
