Product Description

Free Fatty Acids

Free fatty acids (FFAs) are created when a fatty acid chain is cleaved from its parent fat molecule. The level of FFAs is dependent on temperature, moisture content, and time. They also will vary depending on how the fat/oil is stored, processed or heated. When fatty acids cleave from their parent molecule and become an FFA, they are much less stable and more prone to oxidation and to turning rancid. Therefore, testing for free fatty acids is beneficial to monitor the health of your frying oil and final product, since foods will absorb the FFAs causing excessively oily and discolored food with poor taste and probably a shorter shelf life.

How The FoodLab Measures Free Fatty Acids
Free fatty acids of a sample, at pH <7.0, react with a chromogenous compound and decrease in colour. The decrease of colour, read at 630nm, is proportional to the acid concentration of the sample, expressed as % of oleic acid.
