Answer 1

Steps to identify fats in a food item using paper strip:

Take a sample of provided food sample , which is to be tested using paper.

We place the food item on the paper , then fold the paper around the food and crush the item.

Then we unfold and straighten the paper.

Keep the paper under the sun for drying; this step will vaporize any water molecule present in the paper.

Rub the fingers on the paper.

Oily patches (oily , lubricant-like feel on the hand) confirms the presence of fats in the food item.
