This is because heat treatment of milk destroys the vitamins. Thus, heating milk at high temperatures for extended periods of time can destroy these vitamins, especially vitamin D.
Why do Indians boil pasteurized milk?
Before the availability of packaged milk, Indians purchased milk directly from dairy farms. Thus, they followed the process of pasteurization (simply put, boiling) to remove pathogens, disease-causing microorganisms.
Why is milk being pasteurized and not boiled?
Boiling milk certainly destroys all pathogens and makes it safe for human consumption, but there is no need to heat milk at such high temperatures when the same goal is achieved by the pasteurization process.
Is pasteurized milk same as boiled milk?

How do you boil milk without losing nutrients?
In the case of milk cartons, the contents are already pasteurized and do not need to be heated to a high temperature, boiling at 100°C for less than 6-8 minutes. This preserves nutrients,” says Nair.
Does boiling destroy calcium in milk?
A 10-14% reduction in calcium content was observed when unpasteurized milk was boiled. Boiling pasteurized packaged milk reduced calcium content by 6 to 7%. The decrease in calcium content after boiling is related to changes in ionic and soluble calcium in the milk samples.
Does heating milk lose calcium?
Decrease in calcium content A 2016 study found that the calcium content of unpasteurized milk decreased by 10-14% after boiling. It also found that the calcium content of pasteurized milk decreases by 6-7% when boiled .

If milk is taken directly from the cow, it can be retained for 5 days. If packet milk is used, it can last only up to 3-4 days. If the water used to boil the milk is of low quality, it will not last more than 2-3 days.
Why should you never boil milk?
Milk is composed of water, fat, carbohydrates, and protein. When heated, the water begins to evaporate and the other components begin to separate. Boiling too quickly can cause the sugars to burn and the whey protein to coagulate. This will scorch the bottom of the pot and form a skin on top.
How do you know if boiled milk is bad?
Boiling spoiled milk will cause it to separate into whey and solids. It will be sterile, but the taste will still be spoiled. If you like the taste, you can strain the solids through cheesecloth and make real cheese from the solids. Do not drink spoiled milk after boiling.
What is the film on boiled milk?
When milk is boiled, soluble milk proteins denature and coagulate with the milk fat, forming a sticky film on top of the liquid, which dries by evaporation. Since the nutritional value of the proteins is not affected by the denaturation process, the layer does not need to be discarded and can be consumed.
Which milk is better boiled or unboiled?
Nutritional Benefits of Boiled Milk Boiling milk is known to significantly reduce the nutritional value of milk. Studies have shown that boiling milk removes bacteria from raw milk, but also significantly reduces whey protein levels.
