Sudan Red stains lipids. If a sample contains lipids, Sudan Red will show a color - change (usually a red - like coloration).

Step2: Analyze the test results

The vegetable oil (a known lipid - containing substance) shows a red coloration with Sudan Red. If the mystery food sample also shows a red coloration similar to the vegetable oil when tested with Sudan Red, it contains lipids. If it does not show such a coloration, it does not contain lipids.

The mystery food sample contains lipids if the color change does match the color change of the vegetable oil (red - like coloration) when tested with Sudan Red; it does not contain lipids if the color change does not match.
