The test that requires you to rub the food sample on white paper is the **Grease Spot Test**, which is used to identify the presence of lipids or fats in a food sample. When a lipid is present, it leaves a translucent grease spot on the paper. This method exploits the property that fats are insoluble in water but can be absorbed by paper, creating a visible mark.

To conduct this test, follow these steps:

1. Take a small piece of the food sample you want to test.
2. Rub this sample on a clean, white piece of paper.
3. Allow the paper to sit for a few minutes and observe the result.

If a greasy spot is visible after the food sample has been rubbed onto the paper, it indicates that the sample contains fats or lipids. This method is simple and effective for determining whether a food belongs to the lipid food group. It's important to note that this test is qualitative and does not provide information on the quantity of lipids present.
