ABSTRACT:
To increase the yield of soluble solids obtained from tea leaves for preparing instant teas, spent tea residues obtained from tea leaves extracted by a hot aqueous medium are hydrolyzed with cellulase in water to obtain an aqueous extract containing soluble hydrolyzed spent tea residue. To increase yield further, insoluble residue separated from the extract obtained from the cellulase hydrolysis is hydrolyzed with a protease in water to obtain an extract containing further soluble hydrolyzed spent tea residue.
