Both ghee and clarified butter have the milk proteins casein and whey removed and what remains is butter fat. Casein and whey are proteins in dairy that many people do not tolerate, especially people who cannot tolerate gluten. This is because gluten, whey, and casein have a similar molecular structure.

In addition, there is fairly low water content in butter, and often there is added salt as well, which also inhibits bacteria.
