| Abstract: | Tea pigment is a water soluble colored substance, either contained in tea leaves, or derived from enzymatic/non enzymatic oxidative polymerization of tea extracts. According to their color, tea pigments can be classified into thearubigin, theaflavin and theabrowin. In this experiment, technological preparation of tea pigment from non enzymatic oxidation was carried out by adopting orthogonal test, to investigate the key technological factors. Chemical composition, molecular weight distribution and anti oxidative activity of the product were also measured. |
