FIELD: food industry. ^ SUBSTANCE: black locust flowers are sequentially extracted with liquid carbon dioxide and drinking water to obtain CO2-miscella and aqueous extract. Tea production waste is mixed with non-polar liquified gas, extracted and minced along with periodic depressurisation of extraction mixture below extracting agent 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 black locust flowers water extract are entered into suspension, moulded, dried to residual humidity 13-15%. It is followed by cutting, impregnating with CO2-miscella of black locust flowers and gas-liquid extract of tea waste with simultaneous pressure boost, depressurisation to atmosphere pressure with simultaneous freezing of absorbed carbon dioxide and subliming it with obtaining end product. ^ EFFECT: obtaining a new product in form of reconstituted flavoured tea with the fullest usage of mentioned waste. |
