How does invert sugar reduce crystallization in ice creams?
I have often read that invert sugar reduces crystallization in ice creams. But why would that be? Wouldn't dextrose/glucose also offer the same benefits that invert sugar offers?
Best Answer
Simple crystals generally form when you have a lot of a particular chemical with the same shape, and a tendency to bind together. If you stack them as close as possible, you usually get a regular three dimensional array, a crystal. Invert sugar, glucose plus fructose, does not look like or pack like sucrose (glucose-fructose). It does however Hydrogen bond to sucrose. If that sucrose happens to be part of a crystal, that binding introduces a flaw into the crystal structure. This flaw impedes binding of more sucrose to the crystal, hence, smaller crystals.
This phenomena is true not only in ice cream making, but in much of chemistry, where if you want nice big clean crystals, you have to start out with a pretty pure mother liquor i.e. crystallization solution.

How does invert sugar prevent crystallization?
Invert sugars interfere with the crystallization of sucrose, and therefore sugar sauces and caramels are less likely to crystallize if you add a little bit of corn syrup or honey to your recipe.How do you keep ice cream from crystallizing?
Cover ice cream with plastic wrap Press a piece of plastic wrap firmly against the entire surface of the ice cream to prevent ice crystals from forming.What is invert sugar what properties make it useful in baking?
It's formed when the bonds between the sugars in sucrose are broken, resulting in a thick, sweet syrup comprised of 50% fructose and 50% glucose. Invert sugar adds sweetness and helps improve moisture retention and quality in a variety of sweets like ice cream, cakes, cookies, and candy.Does invert sugar crystallize?
It is sweeter than table sugar, and foods that contain invert sugar retain moisture better and crystallize less easily than do those that use table sugar instead. Bakers, who call it invert syrup, may use it more than other sweeteners.What is inverted sugar and how to make it?
