A simple test to check if your green vegetables are adulterated
Green leafy vegetables are great for our health and wellbeing. But what if we tell you that the fresh greens you are getting from the market might be adulterated?
It can be tricky to find out whether the green vegetables you are getting from the market are fresh and pure. But it’s essential to find out as adulterated vegetables can cause various health issues and carry carcinogenic effects.
So, if you are wondering how to detect even the slightest trace of adulteration in the greens that you have got, here is a simple trick by the Food Safety and Standards Authority of India (FSSAI) to detect malachite green adulteration in green vegetables.
Here is a video posted by FSSAI on Twitter to raise awareness about detecting adulteration in green vegetables.
How to test if the vegetable is adulterated
Take a cotton ball, dipped in a soaked liquid paraffin
Rub or dab it in the outer green surface of the green vegetable
If there is no colour change on the cotton, the vegetable is unadulterated
If the cotton turns green, the vegetable is adulterated.
What is malachite green?
Malachite green is a textile dye, which has been used extensively as an antiprotozoal and antifungal medication for fish. It is widely used in aquaculture as a parasiticide in food and health textile and other industries for one or the other purposes. It controls fungal attacks, protozoan infections and other diseases caused by helminths on a wide variety of fish and other aquatic organisms.
It is also used to make vegetables like chillies, peas and spinach look lush green.
Why is it dangerous?
According to the National Center for Biotechnology Information, the toxicity of the dye increases with exposure time, concentration and temperature. It can cause carcinogenesis, mutagenesis, chromosomal fractures, teratogenicity and respiratory toxicity. It can even lead to multiorgan tissue injury.
