Does boiling bagged pure milk affect nutrition?
Boiling pure milk has an effect on nutrition, and the temperature requirement for milk disinfection is not high. It takes 3 minutes at 70℃ and 6 minutes at 60℃. If boiled and the temperature reaches 100℃, the lactose in milk will be coked and caramel will induce cancer. Secondly, after boiling, calcium in milk will precipitate with phosphoric acid, thus reducing the nutritional value of milk.

At the same time, the milk should be poured out and heated, otherwise, if the bagged milk is heated with the packaging, the chemicals in the packaging box or bag will penetrate into the milk, thus causing unhealthy chemical toxicity.
