Question

to test the presence of fat in a food sample​

Answer 1

Answer:

grinding up the food and mixing it with water. Pass the liquid part of the solution through filter paper, squeezing out any 'gunge' - thick bits of the suspension into the same test tube. You should now have a slightly opaque liquid mixture in your test tube.

Answer 2

Answer:

Take a small quantity of the food item to be tested.

Wrap the food item in a piece of paper and crush it.

Straighten the paper.

Dry the paper by keeping it in sunlight for a while.

Observe the paper.

An oily patch on the paper indicates the presence of fats in the tested food item.
