FIELD: food industry.

SUBSTANCE: leaves of cowberry are sequentially extracted with non-polar liquified gas and drinking water with subsequent obtaining corresponding extracts. Tea production waste is mixed with liquid carbon dioxide. It is extracted and minced along with periodic depressurisation of extraction mixture below carbon dioxide vapour pressure at extraction temperature. Extract and extraction cake are separated The latter is suspended in water solution of edible acid. Carbonic acid calcium and magnesium salt and water extract of cowberry leaves are entered into suspension. Then it is moulded, dried to residual humidity 13-15%, cut, impregnated with gas-liquid extract of cowberry leaves and preliminary separated miscella with simultaneous pressure boost. It is followed by depressurisation to atmosphere pressure with simultaneous freezing of absorbed carbon dioxide and subliming it with obtaining end product.
