Refining Agent

Boneblack, also known as bone charcoal, is a refining agent made by roasting animal bones, primarily used in the sugar refining process.

What is Boneblack?

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.

Why People Avoid Boneblack

People, especially those following vegan or vegetarian diets, avoid boneblack because it is derived from animal bones, making it unsuitable for those who abstain from animal products for ethical, dietary, or religious reasons. Although it does not remain in the final sugar product, its use in processing can be a concern for strict vegans and vegetarians.
