The treatment of cooking oils and fats with specific types of sodium magnesium aluminosilicate materials to prolong the useful life of such oils and fats within restaurant settings is provided. More particularly, such an invention encompasses the utilization of calcium-based aluminosilicate materials to filter such oils and/or fats or the incorporation of calcium silicate with or within previously utilized cooking oil filter materials (such as magnesium silicate) for the same purpose. Such calcium silicate-based materials and treatments therewith aid to remove greater amounts of free fatty acids after such oils and/or fats have been utilized to fry foodstuffs, as well as reduce the amount of additional oil and/or fat potentially necessary to bring the used oils and/or fats up to a level of permitted further utilization within a restaurant environment.
