7.Why doesn't ICEE make a sugarfree/diet ICEE? Top: Diet or sugar-free ICEEâs are currently not available. Sugar actually plays two roles in the production of ICEE. First, it helps make ICEE taste great and second, it acts as a âfreezing control.â Without the exact amount of sugar, ICEE would freeze up too hard and would not dispense from the machine to your cup. A lot of research is being conducted to make a sugar free ICEE, but so far, no sugar substitutes have been found that carry the same freezing properties as real sugar.
