Abstract
Abstract A method is provided for increasing the cold water solubility of locust bean gum which comprises adding a predetermined amount of water to the dry gum and subjecting it to an increase in temperature while applying agitation, compression and shear, as in a cooker-extruder. In a preferred embodiment, guar gum is mixed with the locust bean gum in order to enhance the solubility and viscosity characteristics of the final product.

Claim 1
Independent Claim
140 words
A METHOD OF INCREASING THE WATER-SOLUBILITY OF LOCUST BEAN GUM COMPRISING THE STEPS OF: A. PASSAGE SUGAR FREE LOCUST BEAN GUM THROUGH A PROCESSING ZONE FOR APERIOD OF TIME FROM ABOUT 15 SECONDS TO 3 MINUTES, SUFFICIENT WATER BEING PROVIDED IN THE GUM TO CAUSE THE MOISTURE CONTENT THEREOF TO BE AT LEAST AT A LEVEL OF FROM ABOUT 10 TO 65 PARTS BY WEIGHT OF WATER FOR EACH 100 PARTS BY WEIGHT OF DRY GUM; B. APPLYING HIGH COMPRESSIVE AND SHEAR FORCES TO SAID GUM WHILE IN SAID ZONE; C. INCREASING THE TEMPERATURE OF THE GUM IN SAID ZONE WHILE SAID COMPRESSIVE AND SHEAR FORCES ARE APLIED THERETO; AND D. EXTRUDING THE GRUM FROM SAID ZONE, THE TEMPERATURE OF THE GUM BEING INCREASED SUFFICIENTLY IN SAID ZONE SUCH THAT GU, EXIST THEREFROM AT A TEMPERATURE OF FFROM 160*-300* F.
