Ghee, butter, butter oil and anhydrous milkfat are separate identities
Codex defines ghee as obtained exclusively from milk, cream or butter with almost complete removal of water and non-fat solids and an especially developed flavour and physical structure. The same standard lists butter oil and anhydrous milkfat separately. Atlas keeps product name, raw milk source, process, permitted ingredients, jurisdiction and intended use explicit; a value or test attached to one milkfat product is not silently transferred to another.
