In my previous article I have given a detailed overview about what is food adulteration and its types. After reading the article you will have a doubt how as a common man who is going to the market can bring good quality foods that are not adulterated? Here I will tell you some ways to find out the adulteration in the commonly adulterated products. The adulterants used in different food products along with the health effects is clearly mentioned here.


If the stem of the banana appears green, instead of a shiny yellow, it has probably adulterated to ripen.

  • Adulterant: Calcium carbide

The apple will appear very glossy and shiny. It could have slight scratches and you may notice a thin layer peeling off, which is the wax.

  • Adulterant: Wax Coating
  • Effects: Can harm the digestive system. Can lead to ulcers and gastric problems.

Green Vegetables

Common Salt

Stir a small amount of salt in water. If there is chalk, the solution will turn white and other insoluble impurities will settle.

If the colour of the mango is uniform, or if you can find dark green patches around the mangoes on the surface where they are kept, then it is adulterated.

The Annual Public Laboratory Testing Report brought out by the Food Safety and Standards Authority of India (FSSAI) says that of the 49,290 samples of food items it tested, 8,469, nearly one-fifth, were found adulterated. It is better to be safe than sorry.
