PRODUCTION METHOD OF RECONSTITUTED TEA Russian patent published in 2009 - IPC A23F3/40 

FIELD: food industry.

SUBSTANCE: for production of new product - flavoured reconstituted tea, rowa-tree fruits are sequentially extracted by liquid carbon dioxide and drinking water to obtain CO₂-miscella and water extract, tea waste products are mixed with liquid carbon dioxide, 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 obtained miscellas are joined. The extraction cake is dissolved in water solution of edible acid. Calciferous or magnesium salt of carbonic acid and water extract of rowa-tree fruits is added to suspension. Then it is formed, dried till residual humidity 13-15%, cut, impregnated with mixture of CO₂-miscellas with simultaneous pressure boost. After that depressurisation till atmosphere pressure with simultaneous freezing of absorbed carbon dioxide and its subliming with obtaining of end product are performed.

EFFECT: invention allows to obtain new product in form of flavoured reconstituted tea.
