Ethanol Emulsion Test for Lipids
This simple yet effective experiment is used for testing for the presence of lipids.
Take 2ml of given food/oil in a test tube.add 2ml of ethanol in the oil.mix it thoroughy till the oil dissolves. Now add 2ml of water in the test tube.
All of these compounds react together to give a white precipitate. If the precipiatate appears, then the food we are testing contains lipids (fats).
