ADULTERATION OF MILK
The presence of water can be detected by putting a drop of milk on a polished slanting surface. The drop of pure milk flows slowly leaving a white trail behind it, whereas milk adulterated with water will flow immediately without leaving a mark.
Add a few drops of tincture of iodine or iodine solution. Formation of blue colour indicates the presence of starch.
Take a teaspoon of milk in a test tube. Add half teaspoon of soybean or arhar powder. Mix up the contents thoroughly by shaking the test tube. After 5 minutes, dip a red litmus paper in it. Remove the paper after half a minute. A change in colour from red to blue indicates the presence of urea in the milk.
Synthetic milk has a bitter after taste, gives a soapy feeling on rubbing between the fingers and turns yellowish on heating.
ADULTERATION IN KHOYA, CHHENNA AND THEIR PRODUCTS
Boil a small quantity of sample with some water, cool and add a few drops of iodine solution. Formation of blue colour indicates the presence of starch.
