Dec 23, 2012 · #32 Food test 3 - Emulsion (ethanol) test for Fats. This test is done to show the presence of lipids in a substance. The substance is first dissolved in ethanol. This solution is then dissolved in water. If lipids are present in the mixture, it will precipitates and forms an emulsion. General Test for Lipid 2. Solubility Test for Lipid 3. Emulsification Test for Lipid. General Test for Lipid: 1. Sudan III test Procedure: Take 0.5 ml ether or chloroform in a test tube and add 0.5 ml sample—drop by drop till the sample is fully dissolves. Add one drop of Sudan III reagent.

Microscopic examination of stool using Sudan stain to detect fat is the best screening test for fat malabsorption. This test has a 100% sensitivity and 96% specificity. A stool sample is smeared on a microscope slide and mixed with ethanolic Sudan III and glacial acetic acid.
A more accurate test is to place about 1 cm of the substance to be tested in a dry small test tube and add 10 drops of Sudan 11'- Set aside for 30 minutes.
