Test Kit for free fatty acids
Supplier: Merck
Free fatty acids present in an oil or fat sample react with a pH indicator, the colour of which changes depending on the concentration of the free fatty acids. The concentration of the free fatty acids is measured semiquantitatively by visual comparison of the reaction zone of the test strip with the fields of a colour scale. The units of measurement are milligrams of KOH necessary to neutralise the free fatty acids in 1 g of fat sample.
