Abstract
Tea products, particularly black leaf tea and tea powder, derived from green tea leaf are manufactured by a process involving addition of zeolite, preferably a synthetic sodium or potassium zeolite, for reaction with tea ingredients present or subsequently produced to generate red colour species. The tea products produce beverages having enhanced colour characteristics, in terms of colour properties and speed of colour generation, compared with conventional products.
