lipids (fats).

Sudan III is a commonly used stain to detect the presence of lipids in biological samples. When Sudan III is added to a food substance, it will bind to any lipids present and create a visible red coloration. This test is often used to determine the lipid content of food samples, as lipids are an important macronutrient found in many types of food. Therefore, the presence of a red coloration after adding Sudan III to a food substance indicates that the food contains lipids.
