Reason:

Boxed pure milk can be heated, but only if the milk is poured out and heated. Otherwise, if the boxed or bagged milk is heated with the package, the chemicals in the package or bag will penetrate into the milk, resulting in unhealthy chemical toxicity. However, if the milk is poured out, it can be heated, because pure milk is instantly sterilized at high temperature, but it can be heated to boiling and turned off the fire.

Precautions for heating:

It is good to heat milk moderately, and it is best not to overheat it. The longer the milk is heated and the higher the temperature, the more serious the loss of nutrients, mainly vitamins, of which vitamin C is the most serious loss, followed by lactose. Drinking hot milk can make the stomach more active than cold milk, so it can be absorbed to the end.
