摘要： A process for the production of a cold-water soluble instant tea which comprises extracting black tea leaves with hot water, concentrating and cooling the hot-water extract of black tea leaves to precipitate substantially all the tea cream characterized in that the concentrated, cooled extract of black tea leaves is treated with an appropriate quantity of a catechin or mixture of catechins capable of rendering the tea cream soluble in cold water at from 10.degree. C. to 30.degree. C.

摘要： A powdered black tea drink mix is prepared by subjecting to extraction with hot water at a temperature of between about 60.degree. and 130.degree. C., separating the tea leaves from the extract; concentrating this first extract to a solids content of between about 5 and 12% and cooling the first extract to a temperature of between 5.degree. and 15.degree. C. in order to form an insoluble tea cream which is separated from the first concentrated extract. This tea cream is mixed with the spent black tea leaves or with green tea leaves to form a mixture which is extracted with water at a temperature greater than about 70.degree. C. in order to obtain a second extract which is separated from the spent leaves. The first and the second extracts are mixed, concentrated to the desired solids content and dried to form the powdered drink mix.
摘要翻译：通过在约60℃至130℃的温度下用热水提取制备粉红茶饮料混合物，将茶叶与提取物分离; 将该第一提取物浓缩至约5至12％的固体含量，并将第一提取物冷却至5℃至15℃的温度，以形成与第一浓缩提取物分离的不溶性茶奶油。将该茶油与废红茶叶或绿茶叶混合形成混合物，该混合物在大于约70℃的温度下用水萃取，以获得与废叶分离的第二提取物。将第一和第二提取物混合，浓缩至所需的固体含量并干燥以形成粉末状饮料混合物。
