Question

When we rub the food sample containing fat against a white paper what happen​

Answer 1

Explanation:

Test for Fats

An oily patch on paper shows that the food has fats.

Sometimes, the food items may contain a little water.

Therefore, after you have rubbed an item on paper, let the paper dry for a while. If there was any water in the food, it would show up on the paper and dry up after some time.

If no oily patch shows up after this, the food item does not contain any fat
