Emulsion test - wikipedia 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 ( lipids are soluble in alcohols ). The liquid ( alcohol with dissolved fat ) is then decanted into water. Since lipids do not dissolve in water, when the ethanol is diluted, it falls out of solution to give a cloudy white emulsion. Add ethanol to the solution you want to test, and add water. A colour change to cloudy white shows that lipids are present. References Jump up ^ Rothery, Mark. `` Techniques : Biochemical Tests ''.
