Simplesse

Simplesse is a whey protein product used as a substitute for fat in low-calorie foods. The manufacturer, CP Kelco, sells it to food processors as a "microparticulated whey protein concentrate" in dry powder form, and recommends that it be labelled as "dairy protein" on food labels. Its texture is due to its ability to form a colloid, similar to the way fat is dispersed in homogenized milk. It differs from other whey protein concentrate mainly by virtue of rheology; it is produced by a mechanical, rather than a chemical process.
