How to check water contamination in milk?

Milk slip test - Put a drop of milk on a polished vertical surface. If it stops or flows slowly, leaving a white trail behind, it is pure milk. Milk mixed with water or other agents will flow down immediately without a trace.

Reduction test - Boil some milk on a slow heat while moving it with a spoon till it becomes solid (khoya). Take it off the heat and wait for 2-3 hours. If the produced solid is oily, the milk is of good quality; if it’s not, it means the milk is synthetic.

Colours in spices

To check colours in spices like fennel seeds, coriander seeds etc, they should be washed and if they release colour, it means they contain synthetic colours.
