Bleaching Earths
For Edible Oils
Oil-Dri’s Bleaching Earth products offer edible oil refiners processing aids to produce clean, clear, quality oils.
Our Bleaching Earth products are classified into three product families: Natural, Supreme, and Perform. Our product families provide refiners with a range of options, allowing for optimized performance in various refining processes and oils. Oil-Dri’s Bleaching Earth products originate from a unique mineral deposit located near Ochlocknee, Georgia. The clay in this region features a large, highly active surface area well suited for the removal of color bodies and impurities from edible oils.
Natural
Natural products use our clay’s inherent properties to remove impurities in oil without the use of chemical additives. Because these products are naturally active there is no danger of mineral acid carryover in finished oils
