Water test for chalk powder in turmeric
This is easiest of all test and may also be done quickly to find if there is chalk powder added to your turmeric. Here it is:
Take some warm water in a clear glass and then drop 1 teaspoon of turmeric powder on its surface. Just put it and let it do its job – do not stir.
Soon you are going to see chunks of turmeric powder settling at the bottom of the glass. Then plenty of sediments settling too, making the water cloudy.
Check after 20 min, if you see sediment at bottom but the water is clear yellow (not cloudy). Then there’s no chalk powder in the turmeric.
If the water looks cloudy (means you can’t see through the glass clearly), then there perhaps chalk added to the powder.
