FIELD: food products. ^ SUBSTANCE: girasol flowers are sequentially extracted by liquid carbon dioxide and drinking water with obtaining CO2-miscella and water extract. Tea waste products are mixed with nonpolar liquefied gas, extracted and minced with repeating pressure release in the extraction mixture to the pressure lower of extract saturated vapour at extracting temperature. Extract and extraction cake are separated. The latter is dissolved in water solution of edible acid. Calcium and magnesium salt of carbonic acid and water extract of girasol flowers is added to the liquor. It is formed, dried to the residual moisture of 13-15%, cut, and soaked with CO2-miscella of girasol flowers and gas-liquid extract of tea waste products with simultaneous pressure increase. After that depressurisation till atmosphere pressure with simultaneous freezing of absorbed carbon dioxide and its subliming with obtaining of end product are performed. ^ EFFECT: production of reconstituted flavoured tea out of tea production refuses with complete usage of mentioned refuses. |
