First, let’s check out the technique in case you don’t have any milk

Testing kit. Using these techniques, you can check milk quality at home.

If you want to find water adulteration in milk, put a drop of milk on a slightly slanting polished surface like a mirror. If the milk is pure, it will either stay or move slowly, leaving a white trail behind it, or if the milk is adulterated with water, it will move immediately without leaving a mark.

Now, to find detergent adulteration in milk, take 10 ml

of sample with an equal amount of water in a container or a bottle. Shake the

contents thoroughly. If the milk is adulterated with detergent, it will make a

dense lather at the top, whereas pure milk will form a thin foam due to shaking.

Next is starch adulteration; for this, you will need

a tincture of iodine, which can be bought online or from a local chemist shop.

Next, take the 5 to 10 ml of milk sample and add 2 to 3 drops of tincture of

Iodine in it. If the sample shows a change to blue color, it means the milk is

adulterated with starch.

You can also try out some milk testing kits and milk analyzer

chemicals which can be bought online via Amazon or Flipkart. These testing kits

contain all the necessary stuff to check the quality of milk you are getting at

home, and they contain all the necessary instructions on how to use them for

accurate results. So if you want to test out more, give it a try.
