4 Simple Tests Proposed by FSSAI to Detect Adulteration in Milk
Food adulteration, particularly in milk, is a growing concern due to the potential health risks posed by harmful additives. To help consumers ensure the purity of their milk, the Food Safety and Standards Authority of india (FSSAI) has outlined four straightforward tests to detect common adulterants such as detergent, maltodextrin, and indicators of increased acidity or abnormal curdling.
Here’s how you can use these tests to check your milk:
Detecting Detergent in Milk:
Step 1: Pour 5 ml–10 ml of milk into two separate containers.
Step 2: Shake each container vigorously.
Result: Milk without detergent will not form bubbles. If bubbles form, the milk is likely adulterated with detergent.

Result: Milk without detergent will not form bubbles. If bubbles form, the milk is likely adulterated with detergent.
Identifying Maltodextrin:
Step 1: Take a 5 ml sample of milk in a container.
Step 2: Add 2 ml of iodine solution to the milk.
Step 3: Mix the solution thoroughly and observe any color change.
Result: Unadulterated milk will show little to no color change and will appear slightly yellowish-brown. If the milk turns chocolate-red brown, it indicates the presence of maltodextrin, which reacts with iodine to form this color.
Testing for Increased Acidity:
Step 1: Heat 5 ml of milk in a container by placing it in boiling water for 5 minutes.
Step 2: Remove the container from the water without shaking it.
Result: Unadulterated milk will have no precipitates or unusual particles. If you notice precipitated particles or an acidic smell, the milk may be adulterated.
Checking for Abnormal Curdling:
Step 1: Take a sample of milk and observe it for any curdling behavior when heated.
Result: While some curdling is normal in dairy products, abnormal curdling could indicate issues such as high acidity, contamination, improper heat treatment, or adulteration. Fresh milk should not show any unusual curdling when heated.
These tests can help ensure that your milk remains safe and free from harmful adulterants, allowing you to enjoy it with peace of mind.
