FIELD: food industry.

SUBSTANCE: cherry leaves are sequentially extracted with non-polar liquified gas and drinking water with subsequent obtaining corresponding extracts. Tea 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. Miscella 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 cherry leaves are entered into suspension. Then it is moulded and dried to residual humidity 13-15%. After that it is cut, impregnated with gas-liquid extract of cherry 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.

EFFECT: obtaining reconstituted flavoured tea from tea production waste with the fullest usage of mentioned waste.
