The Complete Handbook of Floss Sugar

Chapter 1: Understanding Floss Sugar

What Floss Sugar Is (and Isn't)

Floss sugar is a dry, granular or powdered product that is precisely formulated for one purpose: to be melted and forced through microscopic holes by centrifugal force into a fine, laminated web of sugar. That web is what we call cotton candy, or, in more formal terminology, spun sugar. The product looks similar to very fine granulated sugar or coarse powdered sugar, but the engineering tolerances are much tighter than a simple bag of supermarket sugar. A floss sugar blend contains not just sucrose but a set of functional additives - primarily color, flavor, and a processing aid (usually a fat or an emulsifier) that controls how the sugar melts and how the strands form. Understanding this from the start is helpful, because many operators, especially newcomers, arrive with the assumption that all sugar is the same, only to find that pouring standard granulated sugar into a commercial floss machine either produces no cotton candy at all, or worse, creates clumpy, sticky, scorched residue that destroys the machine head.

The fundamental question, and the one that this opening chapter addresses, is why such a humble-looking product has such strict specifications. To answer it, we need to look at the physics of the cotton candy machine, the chemistry of sucrose, and the economic reality of making cotton candy profitably. The short version is this: sugar barely melts under normal conditions; a machine head must achieve a very precise temperature window;
