Using a lot of phosphoric acid to clean the oil and then a special clay removes almost all of another harmful chemical in the final product.
Using water to clean raw palm oil before refining can cut down one harmful chemical by about half.
A special type of clay used to clean oil works better at removing harmful chemicals if it can trap more stuff, not because it’s more acidic.
If the raw palm oil is of low quality, it creates more harmful chemicals when heated during refining.
How well the clay soaks up bad stuff matters more than how acidic it is when cleaning palm oil.
