How do you test milk at home?

1. Boiling Milk Test:

Boil the milk and observe its behavior:

- Pure milk: Will boil evenly and form a thin layer of cream on the surface.

- Adulterated milk: May boil unevenly, froth excessively, and form lumps or a thick layer of cream.

2. Detergent Test:

Add a few drops of dishwashing liquid or shampoo to a glass of milk:

- Pure milk: Will remain unchanged.

- Adulterated milk: May curdle or foam excessively due to the presence of foreign substances.

3. Iodine Test:

Add a few drops of iodine solution to a glass of milk:

- Pure milk: Will show a slight bluish tinge that gradually disappears.

- Adulterated milk: May turn dark blue or greenish, indicating the presence of starch or flour.

Caution: Always purchase milk from trusted sources and handle it properly to avoid contamination and ensure its safety and quality. If you suspect milk is adulterated, consider having it tested at a reputed laboratory.
