Tea preparation waste is mixed with liquid carbon dioxide, 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 liquid extract of cowslip blossoms are entered into suspension. It is followed by moulding, drying till residual humidity 13-15%, cutting, impregnating with gas-liquid extract of cowslip blossoms and preliminary separated miscella with simultaneous pressure boost, depressurisation till atmosphere pressure with simultaneous freezing of absorbed carbon dioxide and subliming it with obtaining of end product.
