Process of making cold water soluble tea concentrates and powders

A process for manufacturing cold water soluble tea concentrate and powder which comprises preparing a tea extract by extracting tea leaves with hot water, selectively removing nonphenolic compounds of high molecular weight comprising chlorophyll, protein, polypeptide and polysaccharide from said tea extract while retaining polyphenolic compounds therein by subjecting said tea extract to filtration through a gel or solid material which is capable of effecting the separation of said nonphenolic compounds of high molecular weight from said tea extract which contains said polyphenolic compounds and also caffeine and amino acids and then concentrating the resultant filtered tea extract to obtain a cold water soluble tea concentrate or powder.
