Bone-char filtered sugar

Common US / international name: bone char filtered sugar

Origin: Filter aid historically made by charring animal bones; the sugar itself is plant, the processing contact is the issue.
What it depends on: Some cane sugar refining in the United States uses bone char from cattle bones as a decolorizing filter. Beet sugar refining does not. Many brands publish their filter method.
Where it typically appears: White cane sugar and products made with it in markets that use bone-char refining.
Regional note: Bone-char refining is mainly discussed for US cane sugar. In the EU, beet sugar dominates white sugar and bone-char filtration is uncommon.
