ABSTRACT:
Tea extract is separated into a lighter colored and a darker colored phase by changing the natural self-separating capacity of the tea extract by concentrating the extract to 6-45 wt %, preferably 12-30 wt % solids, cooling the concentrate below 5.degree. C. and isolating the separated phases. The lighter colored phase is used in preparing clear cold-water soluble tea, reduced caffeine tea, isotonic tea. The darker colored phase may be used to prepare hot-water soluble instant tea, coloring agent, antioxidant or tea flavoring agent.
