Abstract
Abstract A highly colored, smooth, low viscosity orange base having the natural color, cloud and body of the fruit juice is obtained by treating the natural orange juice so as to deactivate a substantial portion of pectins present in the juice or alternatively, by reducing the Brix level of the juice and then centrifuging, thereby permitting separation of fats and other excess insoluble materials without affecting the natural color, body and cloud of the juice. Selective inactivation of the pectins present in the orange juice is effected by employing specific enzymes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
137 words
A PROCESS FOR PRODUCING A SINGLE-STRENGTH, HIGHLY COLORED, LOW VICOSITY ORANGE BASE HAVING THE CLOUD, COLOR AND BODY OF NATURAL ORANGE JUICE WHICH COMPRISES FIRST DILUTING A SINGLESTRENGTH ORANGE JUICE WITH WATER TO ABOUT 6* TO 7*BRIX AND A VISCOSITY OF ABOUT ONE HALF OF ITS ORIGINAL VALUE, CENTRIFUGING THE DILUTED JUICE TO REMOVE PULP DOWN TO A LEVEL OF 0.3 TO 0.6 PERCENT BY VOLUME, OTHER INSOLUBLE MATERIALS PRESENT DOWN TO A LEVEL OF ABOUT 0.002 TO 0.015 WEIGHT PERCENT AND PECTINS TO ABOUT 0.03 TO 0.05 WEIGHT PERCENT, HEAT-TREATING THE DEPULPED JUICE TO KILL ANY MICROORGANISM PRESENT, AND OBTAINING A HIGHLY COLORED, SINGLE STRENGTH ORANGE JUICE BASE WITH A LIGHT TRANSMISSION WHICH IS NOT MORE THAN A VALUE OF 20 PERCENT TRANSMITTED LIGHT OVER THE PERCENTAGE OF LIGHT TRANSMISSION FOR NATURAL SINGLE STRENGTH ORANGE JUICE.
Claim 2
Dependent Claim

A PROCESS FOR PRODUCING A SINGLE-STRENGTH, HIGHLY COLORED, LOW VICOSITY ORANGE BASE HAVING THE CLOUD, COLOR AND BODY OF NATURAL ORANGE JUICE WHICH COMPRISES FIRST DILUTING A SINGLESTRENGTH ORANGE JUICE WITH WATER TO ABOUT 6* TO 7*BRIX AND A VISCOSITY OF ABOUT ONE HALF OF ITS ORIGINAL VALUE, CENTRIFUGING THE DILUTED JUICE TO REMOVE PULP DOWN TO A LEVEL OF 0.3 TO 0.6 PERCENT BY VOLUME, OTHER INSOLUBLE MATERIALS PRESENT DOWN TO A LEVEL OF ABOUT 0.002 TO 0.015 WEIGHT PERCENT AND PECTINS TO ABOUT 0.03 TO 0.05 WEIGHT PERCENT, HEAT-TREATING THE DEPULPED JUICE TO KILL ANY MICROORGANISM PRESENT, AND OBTAINING A HIGHLY COLORED, SINGLE STRENGTH ORANGE JUICE BASE WITH A LIGHT TRANSMISSION WHICH IS NOT MORE THAN A VALUE OF 20 PERCENT TRANSMITTED LIGHT OVER THE PERCENTAGE OF LIGHT TRANSMISSION FOR NATURAL SINGLE STRENGTH ORANGE JUICE.
Claim 3
Dependent Claim
19 words
The process of claim 1 wherein the described insoluble materials are removed by depulping with a high-speed desludge centrifuge.
Claim 4
Dependent Claim
37 words
The process of claim 1 wherein the diluted, depulped orange juice is heat-treated at about 200*F. and then concentrated to about 64* to 80* Brix by removal of a portion of the water present in the juice.
Claim 5
Dependent Claim
33 words
The process of claim 1 wherein the diluted, depulped orange juice is heat-treated to about 200*F. and concentrated to about 64* to 80* Brix and has a viscosity of 500 to 700 centipoises.
Claim 6
Dependent Claim
15 words
The process of claim 3 wherein the single-strength juice is concentrated in a vacuum evaporator.
