Watch out brief demonstration of Urea Kit for On-Site Testing of adulterated milk by Dr Gulshan Narang (D.I.O, Veterinary Public Health and Epidemiology, LLR UVAS) carried out at Toxicological D. I. Lab of Veterinary Public Health and Epidemiology Department of LLR UVAS Hisar.
To get more profits, some milkman prepared synthetic milk which is very cheap and sold at the rate of natural milk. Synthetic milk consists of vegetable fat, detergent powder and urea mixed in water containing salt. This milk is similar to natural milk in colour, fat content, smell, taste and specific gravity. Around 1.0 percent urea is added to make up normal protein levels of the synthetic milk.
Consumption of synthetic milk or its product like urea can damages liver, heart and kidneys and also causes swelling of limbs and impaired vision.
There was a need for rapid tests for the detection of urea in the milk to prevent the adverse health hazards to common man.
Dr Gulshan Narang and Dr R. S. Khokhar of the Veterinary Public Health and Epidemiology, CoVS, LLR UVAS has developed a field spot test to detect urea in milk.
The principle of test is that urea reacts with the indicator giving a colored reaction which can be visualized within a minute.
Usually 0.9 to 1.0 percent urea is added for making synthetic milk. Urea is added to make the protein content and increasing the SNF content of the milk. Without addition of urea the protein levels of the milk can not be achieved.
- Put a drop of indicator solution A on the filter paper and let it absorb.
- Put a drop of the test milk sample on the indicator drop.
If our test milk develop immediately yellow colour around the milk drop, it means our simple is mixed with Urea. That sample is contaminated with the Urea.
The Milk Urea Detection Kit is easily available for common man at Kisan Seva Kendra, HAU CCS Gate No.4 (Hisar, Haryana)
If any Person wants to initiate the commercial production of Urea Kit, He can Contact Dr N. K. Kakker of Business Planning and Development (Veterinary Products) Unit of LLR UVAS, Hisar for getting license of this kit for specific period of years.
The business person can improved the urea kit by providing other solution for detecting soda, starch and detergents in the milk sample.
