Patent ID: 8282962

Claim:
A composition comprising by weight of dry matter at least 50% of xanthan gum and not more than 30% of starch, wherein the xanthan gum is not treated with glyoxal or adipoyl chloride and the xanthan gum can be dispersed completely within 2 minutes in distilled water at 25° C. at a concentration of 0.7% based on the dry weight of xanthan determined by a method comprising introducing 500 ml of distilled water to a beaker of 1000 ml, stirring the water with a four bladed impeller of 5 cm diameter operating at fixed rate of 300 rpm, and adding the composition to the water until a concentration of 0.7% based on the dry weight of xanthan is reached, wherein the composition has a first viscosity of less than 500 mPa·s at 23.8° C. and a second viscosity of at least 600 mPa·s at 23.8° C., wherein both the first and second viscosities are determined according to Section 172.695, Title 21, Volume 3 of the Code of Federal Regulations of the U.S. Food and Drug Administration, the first viscosity measurement comprising the steps of: a) adding the composition to an aqueous solution containing 1 wt. % potassium chloride to give an aqueous composition containing 1 wt. % xanthan gum; b) stirring for 2 hours; and c) determining the viscosity of the stirred aqueous composition by Brookfield viscometer Model LVF viscometer or equivalent using a No. 3 spindle at 60 rpm; and the second viscosity measurement comprising the steps of: d) heating the stirred aqueous composition of (c) immediately after the first viscosity measurement to a temperature of 100° C.; e) maintaining a temperature of 100° C. for one minute; f) cooling to 23.8° C. within 120±10 minutes; and g) determining the viscosity by Brookfield viscometer Model LVF or equivalent using a No. 3 spindle at 60 rpm.
