Bleaching earths have been an essential part of the edible oil refining process since late 19th century. While advancements in technology and techniques have improved

Why focus on Trace Elements? Each step in vegetable oil refining plays a critical role in improving oil quality. The bleaching stage is the final

3-monochloropropane-1,2-diol esters (3-MCPD) and glycidyl esters (GEs) are toxic, potentially carcinogenic compounds often found in processed palm oil products. These compounds are closely monitored by

Deodorization is typically the last step in edible oil refining. The process removes compounds such as carotenoids, free-fatty acids, tocopherols, aldehydes, peroxides, and others. Laboratory

Here at Oil-Dri, we have been performing laboratory scale experiments mimicking a variety of different processes for bleaching edible and non-edible fats and oils for

At our laboratory in Vernon Hills, Illinois we can simulate various commercial fat and oil refining processes. Two processes that are commonly performed in our
