Question

Explain some simple techniques used to detect adulterants at home.

Answer 1

1. Milk: Place a drop of milk on a polished surface. Pure milk flows slowly, leaving a trail behind. Milk with water will flow fast, without leaving a trail.
2. Honey: Dip a cotton wick in Honey and light it with a match stick. Pure Honey bums, but adulterated honey gives a cracking sound.
3. Sugar: Dissolve sugar. If chalk powder is added as an adulterant, it will settle down.
4. Coffee Powder: Sprinkle a few pinches of Coffee powder in a glass of water. Coffee powder floats. If it is adulterated with Tamarind powder, it settles down.
5. Food Grains: Foodgrains are mixed with stones, sand grit, marble, etc. They are removed by Sorting, handpicking, and washing.
