Abstract
Abstract Process for producing a slush comestible concentrate wherein a noncrystallizing saccharide mixture is converted into a concentrate that is spoonable and dispersable at 0*F. in water, milk or whiskey forms large water ice crystals and 35-50% overrun during the crystallizing process, cellulose gum being used to reduce phase separation of the slush concentrate and impart desired organoleptic qualities.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
119 words
A PROCESS FOR PRODUCING A FEFRIGERATION-STABLE SLUSHED COMESTIBLE CONCENTRATE THAT IS SPOONABLE AND STIRABLE AT 0*F WHICH COMPRISES PARTIALLY CRYSTALLIZING A SACCHARIDAL, AQUEOUS HYDRATED GUM-CONTAINING VISCOUS SOLUTION TO FORM ICE CRYSTALS HAVING A SIZE OF 200 TO 500 MICRONS BY SLOWLY GROWING ICE CRYSTALS AFTER THE SOLUTION IS COOLED TO BELOW ITS ICE POINT AND CONTINUING SAID CRYSTALLIZING PROCESS WHILE AGITATING THE SOLUTION TO INDUCE AN OVERUN OF 35-50% AND WHILE INCORPORATING A GASEOUS PHASE THEREIN UNTIL A STABLE TERTIARY PHASE OF CONCENFORMED IN A GASEOUS FORM AT A TEMPERATURE OF 15*-20*F, 75 TO TRATED SYRUP MATRIX INTERSPERSED WITH COARSE ICE CRYSTALS IS 90% OF THE WATER ORIGINALLY PRESENT IN SAID SOLUTION BEING THEREBY CONVERTED TO SAID ICE CRYSTALS.

Claim 3
Dependent Claim
16 words
Process of claim 1 wherein said crystallizing proceeds over a period of at least two hours.
Claim 4
Dependent Claim
25 words
Process Of claim 2 wherein a numerical majority of the ice particles have a dimension of at least 200 microns in all three major axis.
Claim 5
Dependent Claim
14 words
Process of claim 2 wherein the crystallized solution has an ice point of 25*-27*F.
Claim 6
Dependent Claim
22 words
Process of claim 4 wherein the ice is crystallized in a tank having a surface to volume ratio of 0.7 to 2.6.
Claim 7
Dependent Claim
21 words
Process of claim 5 wherein the gum is an ionic cellulose gum and said solution has a viscosity of 14 millipoises.
Claim 8
Dependent Claim
20 words
Process of claim 1 wherein the saccharide comprise at least 25% invert sugar by weight of the total beverage solids.
Claim 9
Dependent Claim
