Boneblack and the Onion Free Diet

Boneblack, or bone charcoal, is created by heating animal bones in a low-oxygen environment, resulting in a form of carbon. This substance has been used historically for a variety of purposes, including as a pigment and a filtering agent. In the food industry, it is sometimes used in the refining process of cane sugar, where it helps to decolorize and purify the sugar, although it does not remain in the final product.
