Simple Tests to check Adulterated Sweets

Diwali comes to an end however the piles of gifts and sweets remain. Our diet plans don’t stop us from indulging, however can we stop and think if these sweets are safe to eat? Are they safe to consume? It is difficult to resist the temptation, but it is paramount to know if the food is adulterated especially if the sweets or snacks are purchased from shops.

Every year, the food safety departments receive complaints from various cities and towns.

The concerned authorities are giving special focus to milk and milk products. We have some simple tests to check adulterated sweets.


Milk adulteration in India is a rampant business that comes at the cost of our health. The adulterants in milk are found to be water and additives like chalk, urea, detergent and chemical whiteners.

Test for water in milk-
  • Put a drop of milk on a polished, slanting surface
  • Pure milk either stays or flows slowly leaving a white trail behind
  • Milk adulterated with flow immediately without leaving a ma
Test for Detergent in milk-
  • Take 5-10 millilitres (ml) of milk sample and equal quantity of water
  • Shake the mixture well
  • If the milk is adulterated with detergent, it forms dense lather
  • Pure milk will have a thin layer of foam



  • Simple tests to check the purity of Ghee.
  • Test 1-Put a spoon of ghee on your hand, if it starts to melt itself that is pure. Usually, pure ghee melts with your body temperature.
  • Test 2- Take a spoon of ghee and heat it. If it melts quickly and appears dark brownish colour, that means it is pure ghee. it takes few seconds for pure ghee to melt, however if it takes a longer time to melt and appears light yellow in colour, it is not pure.



  • Khoya or mawa makes the sweet delicacies taste so delicious. The presence of starch in khoya is detected by this test:
  • Boil 2-3 ml of sample with 5ml of water. Cool and add 2-3 drops of tincture of iodine. Formation of blue color indicates the presence of starch. One can also buy khoya testing kits that are available in medical stores.



  • Vark (silver-leaf foil) on top gives makes our Kaju Kati look so appealing however it can also be the cause of worry. Quantity exposed is very less so we will not face immediate health degradation but if consumed for longer run, this can cause severe illness to our body.
  • A simple test is try to wipe off the silver leaf on top of sweets with your fingers. If the residue sticks to the fingers, it means that the vark is adulterated with aluminium. If it doesn’t, then it means the sweets are safe to eat.
  • As the season for Diwali ends, you can now easily indulge your sweet tooth and not feel unsafe with the simple tests. Go ahead, have some Mithai.
