How do you choose which eggplant to pick when you go vegetable shopping? If you follow conventional wisdom, you would likely go for the shinier and smoothest one of the lot. The adulterators know that well, that is why they ensure that the brinjals on vegetable shelves look smooth and shiny.
Adulterants used in brinjal
Wax:
A wax coating on eggplant ensures that it
- does not lose water (helps in extending shelf life)
- looks shiny and smooth (helps in enhancing appearance)
Engine Oil:
The coating of engine oil serves the same purpose as wax. Use of purple colour silica spray further adds to the appeal by making it appear shiny and rich.
How to identify adulteration in brinjal?
- Scratch the peel of brinjal with a spoon. A white substance at the end of the spoon will show the presence of wax.
- Take a cotton swab dipped in liquid paraffin wax (or you can try with a handy nail polish remover). Rub it on the outer surface of the eggplant. Presence of purple colour on cotton would indicate the use of Silica dye.
How to remove wax from eggplant?
Make a paste of baking soda and white vinegar. Apply this paste to eggplant. Rinse it and dip in warm water for a few minutes. This will help in separating wax.
