Alcohol Milk Testing Gun Stainless Steel

An alcohol gun is a stainless steel milk testing device that uses a 68% ethanol solution to indicate if fresh milk will thicken during thermal processing. The test is performed by mixing equal parts milk and ethanol in a test tube or small bottle, and then attaching a glass beaker to check for precipitation or clotting. 

The alcohol test is based on the idea that milk proteins become unstable when the milk's mineral balance is disrupted. Milk that has high acidity or higher than normal amounts of calcium and magnesium compounds will coagulate when alcohol is added. For routine testing, 5 ml of milk is mixed with 5 ml of ethanol solution. If the milk is good quality, there will be no clotting, precipitation, or coagulation. The presence of flakes or clots indicates poor quality milk.
