We Pakistan proudly called ourselves ‘The Citizens of Islamic Republic of Pakistan’ and the truth is that except the world Islam in our official country name; there is nothing pure in Pakistan. We don’t even bother to think about what we are doing with the lives of others. Our actions are putting a bad name on the name of country and religion.

Just take the example of milk that is hard to found in pure form in Pakistan either it is natural milk, powder, or tetra pack milk. In June 2016, Barrister Zafarullah filed a petition in Supreme Court of Pakistan and disclosed that impure milk is being sold in Pakistan. Because of this milk, millions of people in Pakistan become the victim of deadly diseases.

Still, some milkmen are doing their jobs honestly. Here we are presenting the ways to find for adulteration in milk.

Reduction Test

Reduction Test is the very simple test to check the quality of milk. Boil milk on low heat for two to three hours to make Khoya. Rough residue or rocky solid state of this Khoya states that milk is adulterated. If it is oily, then it means you are using good quality milk.

Slanting Test

This is the simplest one method. Put few drops of milk on a polished slanting surface. If it will pure then it will leave a white trail behind while flowing slowly and in the case of impurity, it will leave behind water only.

Rice/Dalda/Ghee/Oil in Milk

Add 1 tbsp of sugar and 2 tbsp of hydrochloric acid to milk. If the mixture turns red, then milk is impure.

Lather Test

Mix 2 teaspoons of milk and water and shake properly. The presence of detergent will be indicated by lather.

Litmus Test

Take three teaspoons of milk in a small container. Add half teaspoon of arhar power or soybean and shake the container. After five minutes, dip a red litmus paper. If the color turns from red to blue, then it indicates the presence of urea.

Starch in Milk

Add 2 tablespoons of salt to 5 ml of milk to form the mixture. If the mixture turns blue, then it is adulterated. Otherwise, it will remain intact in case of not adulterated.
