Bleaching Earths

Bleaching Earths For Edible Oils

Oil-Dri offers edible oil refineries bleaching earth products to produce clean, clear, quality oils. Our Bleaching Earths are classified into three product families: Natural, Supreme, and Perform. Our range of product families offers refiners a diverse array of choices, allowing for optimized performance in various refining processes and oils. All our Bleaching Earth products trace their origins to a unique mineral deposit near Ochlocknee, Georgia. The clay sourced from this region boasts a large, highly active surface area, making it particularly effective in removing color bodies and impurities from edible oils. Rely on Oil-Dri’s expertise and quality solutions for an unparalleled refining experience.

Natural

Harnessing the inherent properties of our clay, Natural products efficiently eliminate impurities from oils without the need for chemical additives. The natural activity of these products ensures a clean and clear final product. Notably, our Natural line is certified organic, presenting an excellent choice for those seeking to adhere to rigorous organic processing standards in the refinement of edible oils.
