The new monitors are designed to measure total polar materials in frying oil. Polar materials may be defined simply as all non-triglycerides in cooking oil. Fresh oils, prior to the initiation of frying, usually contain 2 to 4 percent polar materials. Once frying starts, oils begin to degrade, a process that is irreversible.
