Today we will tell you some simple tests to detect food adulteration.

The Biochemical tests are useful for checking food adulteration.

There are many biochemical tests that are performed in the laboratory to test food but today I am going to show you some helpful tests which can be performed at home along with a few biochemical tests to detect food adulteration.

To check the presence of brick powder first take one glass-bowl or plate. Take some chili powder and rub it on the bottom of the glass-bowl or plate. If you feel some kind of grittiness it means that there is a brick powder mixed with red chili powder. And it is not safe to consume.

Red chili powder may also have artificial color. To check the chili powder, just sprinkle a pinch of chili powder over a glass of water and wait for some time. If you see color are streaking out it means your chili powder is adulterated.

There is a biochemical test to check the purity of turmeric powder. Metanil Yellow is added to turmeric powder. To check the presence of metanil yellow, add a few drops of concentrated hydrochloric acid in water and add a spoonful of turmeric powder in the same water. If it turns pink then the turmeric powder is adulterated.

You can also add a spoonful of turmeric powder in 20ml lukewarm water and add a few drops of lemon or ascorbic acid. If the water turns pink, purple or violet then it indicates that the turmeric powder is adulterated. Metanil yellow which is added to turmeric powder is highly carcinogenic in nature.

Mix a tablespoon of sugar and salt in a glass of water. Sugar or salt will dissolve in water and chalk powder will settle down and will give a smell of ammonia. Ammonia is highly toxic to the human body.

Sprinkle some coffee powder over a glass of water. The coffee powder will float in water whereas the tamarind seeds will sink within a few seconds. Tamarind seeds are very harmful because it can cause diarrhea and severe joint pain.

Dip one cotton ball in honey. Take a matchbox and try to burn the cotton ball. It will burn easily if it is pure but if it is adulterated with water, the water will not allow the cotton ball to burn.
