How to heat bagged milk is the healthiest

Bagged milk is milk packed in plastic bags. It is best to cut open the package and pour it into a milk pot or cup for direct heating or boiling for 3-5 minutes. Because the time is not easy to grasp if the plastic bag is heated directly, harmful substances will volatilize if the temperature is too high, which is not worth the candle; If the time is short, the heating effect will not be achieved. Therefore, it is healthier to prepare a milk jug or heater.
