EDIBLE OILS CONTAIN A LOT OF
UNDESIRED SUBSTANCES AND IMPURITIES

To give edible oil a long storage life and make it heat resistant as well as neutral in taste and odor it has to be purified. All undesired substances, like gums, dyestuffs, peroxides, heavy metals, and residues of crop protectants, have to be removed from edible oil whilst preserving the nutrients.

Solution

Highly active bleaching earth based on natural resources improves oil quality considerably

Tonsil® bleaching earth 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 bind all undesired accompanying substances and impurities from the oil.
