Question

test for protein



test for fat​

Answer 1

Test for protein :-


Biuret solution is used to identify the presence of protein. Biuret reagent is a blue solution that, when it reacts with protein, will change color to pink-purple.

Test for fat :-


The first involves 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. Because fat is less dense than water, if you leave this mixture it will separate out into a layer of fat and a layer of water.
