How To Check The Purity Of Milk: Food adulteration poses a significant threat to public health and we often hear the adulteration practices which highlights the urgent need for vigilance and action. Milk, used daily in millions of Indian households is often contaminated with harmful additives like water, detergent and urea. This can lead to severe health issues, especially among children and the elderly. Impure milk can lead to digestive issues, allergies, vomiting and long-term health problems. Thus, testing milk purity is crucial to ensure safety and overall well-being.
Simple Milk Detection Tests At Home
Milk Water Test
Place a small milk sample on a plain surface. If it flows slowly, maintaining its shape, it's likely pure. However, if it spreads quickly and thinly, water has likely been added with milk. Thus, it is one of the easiest ways to check the purity of milk.
Milk Detergent Test
Detect detergent in milk with a simple shake test. Mix equal parts milk and water in a bottle. Shake vigorously for 30 seconds. If a dense, frothy lather forms and persists, then it has detergent. Pure milk will produce minimal foam that quickly dissipates.

Synthetic milk, a harmful imitation is made from vegetable oils, urea, and harmful additives. To detect its impurity, taste a few drops, a bitter taste indicates synthetic milk. Alternatively, rub a drop between your fingers, a soapy feel reveals that it is adulterated.
Milk Urea Test
For this test, mix one teaspoon of soybean powder with 10 mL of suspected milk. Shake well and insert red litmus paper. If the paper turns blue, urea is present. This reaction occurs due to urea's alkaline properties. This homemade test provides a quick and effective way to identify adulterated milk.
