There are countless advantages of including pure milk in your regular diet. Minerals, vitamins, and other minerals necessary for growth can be found in abundance in these foods. Moreover, milk can enhance the quality of your skin and make it shine. Still, it pays to exercise caution when picking up milk. Brands often dilute their milk with cheaper ingredients to increase their profit margin. It's imperative that you never drink tainted milk. The effects on your body may be detrimental rather than beneficial.
Here’s how to check its purity at home
Boil it: To determine if milk has been tampered with, boil it over a low flame for a few hours until it thickens. Once it hardens completely, examine the residue. The milk has been tainted if it's gritty. However, high-quality milk will leave behind an oily sheen.
Synthetic milk is the product of a number of chemical reactions. It looks like pure milk, but it doesn't taste anything like milk at all. Bad-tasting artificial milk is easy to spot. When heated, its soapy texture softens and it takes on a yellowish hue.
Slightly incline your palm and place a drop of milk there. Pure milk flows slowly and leaves a white trail behind it. If it quickly disappears without leaving a white trail, however, it has likely been diluted with water. Watered-down milk might not be dangerous to your health, but it's certainly a waste of money.
It's common practise to stain milk with scratch. You can use iodine to determine its authenticity. Add a sprinkle of salt to five millilitres of milk and stir. Starch will cause the mixture to turn blue if it has been added. The colour won't change otherwise.
Manufacturers routinely add formalin to milk to extend its shelf life, and the sulphuric acid test can detect its presence. Since it lacks opaqueness, it is impossible to recognise. Adding a few drops of sulphuric acid to 10 ml of milk is a simple way to determine whether or not the milk has been adulterated. The milk is not good if there is a blue ring where the layers meet.
