A positive test for fats typically involves using a method such as the Sudan III test or the grease spot test. In the Sudan III test, a positive result is indicated by the presence of a red-orange coloration in the sample, signifying the presence of lipids. In the grease spot test, a positive result is characterized by a translucent spot on filter paper, which suggests the presence of fats or oils. Both tests demonstrate the lipid content in the sample effectively.

The exact appearance will depend on the specific test method employed.
Does coconut oil give positive result on molisch test?
Coconut oil typically does not give a positive result in the Molisch test, as this test is designed to detect the presence of carbohydrates, particularly sugars. Coconut oil is primarily composed of fats and does not contain significant amounts of carbohydrates. Therefore, it generally does not react with the reagents used in the Molisch test.
