Can you boil milk to extend life?
A rapid heating and cooling of milk significantly reduces the amount of harmful bacteria, extending its shelf life by several weeks. New research shows that increasing the temperature of milk by 10 degrees Celsius for less than a second eliminates more than 99 percent of the bacteria left behind after pasteurization.
Does milk go bad if boiled?

Does boiling milk kill viruses?
BOILING AND PASTEURIZATION
Boiling water kills or inactivates viruses, bacteria, protozoa and other pathogens by using heat to damage structural components and disrupt essential life processes (e.g. denature proteins). Boiling is not sterilization and is more accurately characterized as pasteurization.
Does boiling milk destroy vitamins?
Vitamins and proteins are denatured and destroyed when milk is boiled at temperatures above 100 degrees Celsius for over 15 minutes. Milk is a vital source for Vitamin D and Vitamin B 12, which help in calcium absorption. Both these vitamins are highly heat sensitive and boiling milk destroys both substantially.
Why does milk last longer in a carton?
The process that gives the milk a longer shelf life is called ultrahigh temperature (UHT) processing or treatment, in which milk is heated to 280 degrees Fahrenheit (138 degrees Celsius) for two to four seconds, killing any bacteria in it.
