Abstract

1,156,248. Conversion of green tea. UNILEVER Ltd. 7 Sept., 1967 [9 Sept., 1966], No. 40866/67. Heading A2B. In the conversion, i.e. oxidation, of green tea, that is to say, fresh or fired green leaf tea or extracts thereof, to black tea, the green tea is treated with a waterimmiscible organic solvent, such as chloroform, petroleum ether, methylene chloride, dichloroethylene, trichloroethylene, benzene, hexane, or iso-octane, to reduce the time required for conversion. Water-soluble solids may be extracted either during or after the treatment, for example with water or preferably a mixture of acetone and water.
