Patent ID: 7829697

Claim:
A process for the preparation of a clarified high acyl gellan solution, comprising the steps of: (a) heating an aqueous gellan solution to a clarification, temperature of 30 degrees C. to 70 degrees C.; (b) treating the aqueous gellan solution with at least one chelating agent; (c) after step (b) treating the chelating agent treated aqueous gellan solution with lysozyme enzyme; (d) treating the aqueous gellan solution with a caustic agent or an oxidizing agent; (e) treating the aqueous gellan solution with a protease enzyme; and (f) recovering the clarified gellan by precipitation with an alcohol, wherein the resulting clarified gellan upon dissolution at 1% w/w has a light transmittance of greater than 80% measured at a wavelength of 600 to 650 nm.
