Activated Bentonite / Bleaching Earth

Activated Bentonite is a highly Active Bleaching Earth. It is a semi-coarse powdered substance that is commonly used in the refining of animal fats and vegetable oils.

Activated Bentonite or bleaching earth is derived from the natural clay mineral bentonite has a purifying effect. It is formed by an acidic activation of bentonite, which changes its special layered structure: the ion exchange with the protons enables additional water to enter between the layers and the mineral swells.

The surface area thereby increases fivefold. The activated and greatly enlarged surface can gently remove undesired compounds. Pigments, gums, and other substances can unfavorably affect the appearance, taste, odor, and shelf life of edible oil.
