The test for presence of fat in food is :
● Shake or crush the food to make it dissolve. Filter or dilute the food and ethanol mix so that you get a clear liquid (a solution of fat in ethanol).Add this to a test tube of water .A white(milk-like)emulsion indicates the presence of fats (or oils).
● Rub a piece of walnut,groundnut, a piece of butter on a plane paper.The spot rubbed turns translucent especially when viewed against light. This is another test for fats or oils.
Hope it helps you!!
