Abstract

PURPOSE: Aqueous extract of various kinds of tea is treated with a specific adsorbent and flocculant to remove substances causing discoloration, thus producing tea extract or instant tea of better color.
CONSTITUTION: Aqueous extract of green tea, roasted tea, half-fermented tea or fermented tea is treated with polyamide such as nylon, a polyamine high-molecular compound bearing primary or secondary amino groups every 2W6 carbon bonds, aluminum oxide so-called activated alumina, or a concentrated aqueuous solution of methyl cellulose and the pH is adjusted to 4.0W7.5 to remove the preciptitate or flocculate by centrifugation or filtration whereby the tea extract free from substances causing discoloration is obtained. After treatment, the tea extract may be freeze- dried into a dried powder to give an instant tea.
