Emulsion test

Emulsion test

The emulsion test is a method to determine the presence of lipids using wet chemistry. The procedure is for the sample to be suspended in ethanol, allowing lipids present to dissolve. The ethanolic solution is then decanted into water. Since lipids do not dissolve in water, when the ethanol is diluted, it falls out of solution to give an emulsion.
