Observing the color change in the mixture
Protein Test:
- In the test for protein in food items, one of the essential steps is to observe the color change in the mixture.
- This is typically done by adding a few drops of copper sulfate solution to the food sample and then adding caustic soda solution.
- If protein is present in the food item, the mixture will change color to violet or purple due to the formation of a complex between the protein and copper ions.
Fat Test:
- Similarly, in the test for fats in food items, observing the color change in the mixture is also crucial.
- This test involves placing a small amount of the food sample on a piece of paper and allowing it to dry.
- If fats are present in the food item, an oily patch will appear on the paper as the fats leave a translucent mark.
- By observing this color change, one can determine the presence of fats in the food sample.
In both tests, the observation of the color change in the mixture serves as a key indicator of the presence of protein or fats in the food item being tested.

A common essential step in both the tests for protein and fats in food items is the observation of the color change in the mixture. In the test for proteins, a violet color indicates the presence of proteins, while in the test for fats, an oily patch on the paper signifies the presence of fats. Therefore, observing the color change is a crucial aspect of both tests to determine the presence of specific nutrients.
