The fats and oils in margarine include triglycerides consisting of various types of fatty acids. With the margarine analyzed, melting peaks of various triglycerides are visible across a wide range of temperatures (from -33 to +22.4˚C). In this example, the partial area analysis program was used to calculate the heat of fusion from peak-start to specified temperatures.
