The Official American Oil Chemists’ Society (AOCS) Ca 5a-40 method for the determination of free fatty acids is based on titration of an ethanolic solution and requires a large volume of organic solvents, large sample aliquots, and up to eighteen hours extraction time for some samples. The SafTest Free Fatty Acid Test Kit is a rapid method designed to measure free fatty acid content of vegetable oils; fish oil; animal fats (tallows); meat meal and fish meal products; and crackers, chips and other processed grain-based snack products using micro-analytical and membrane separation principles.
