Are You Eating Adulterated Vegetables? Do These Tests To Check Adulteration

Food adulteration is a highly concerning issue in recent times. Many vendors sell adulterated food or food with adulterants risking the lives of people for some profit. From adding synthetic colors and chemicals to increase the appeal of veggies to wax coating for a shinier look to injecting pesticides for ripening, there are numerous components of adulteration that we generally miss out on. All of us need to be aware and do purity check if you see a fruit or vegetable with perfect color and shine. Adulterations tests are very simple and hardly takes 5 minutes to check a basket of veggies. What are you waiting for then? Read ahead to know the process to find whether your food is adulterated or not.

Green Peas

Green peas are also adulterated the most in order to make them look fresh. People assume the pea pods to be fresh by looking at the color of the skin. Here is a small test that you should do:

  • In a transparent glass, put some green peas.
  • Now, add water to it and stir it.
  • Keep it aside for half an hour.
  • If the water turn green, peas are adulterated. If not, they are safe.

Green Vegetables

You may not know this that green vegetables are the ones adulterated the most. While the green color is associated with freshness, many people presume green veggies to be fresh by looking at their color. This is the biggest mistake. Attractively green or shiny green surfaces are mostly due to adulterants. The fresher the food, the pastel it would look from outside.

Malachite green is a chemical dye using which green veggies like chillies, peas, etc. are adulterated. This is carcinogenic and may cause cancer if you consume it for prolonged periods.

Here are two tests to identify malachite green in vegetables.

Test 1

  • Take some cotton and soak it in oil.
  • Now, rub the vegetable with this cotton.
  • If it has adulterants, the cotton would turn green.
  • Alternatively, you can also do this test with water. 

Test 2

  • Take a white paper and moisten it with water.
  • Place the vegetable on it.
  • After 8-10 seconds remove the vegetable and see if there is a green-colored impression on the paper.
  • If yes, the vegetable is adulterated with artificial green color.

Rhodamine B in Sweet Potato

Rhodamine is an adulterant which gives a pinkish color to sweet potatoes. Here is how you can find the difference:

  • Soak a cotton ball in the water.
  • Rub it on the skin of the sweet potato.
  • If your cotton turns pink, it is a sign that is it being adulterated.
  • You can also do this test with vegetable oil for double-checking.
