Can plastic bottles of milk be heated in a microwave

It is not recommended to directly heat plastic bottles of milk in a microwave oven. Plastic bottles may release harmful substances and pose safety hazards at high temperatures. It is recommended to pour them into a microwave specific container for heating.

Plastic bottles may deform or release chemicals in high temperature environments, and common plastic bottle materials such as PET have decreased stability when the temperature exceeds 70 degrees Celsius. Some plastic bottles are labeled as heat-resistant, but long-term heating may still release plasticizers and other components, affecting milk quality and human health. During microwave heating, the local temperature may exceed the plastic's tolerance limit, causing the bottle to melt or produce toxic compounds. The fat and protein in milk are more likely to adsorb harmful substances in high-temperature plastic containers. In special circumstances, if the plastic bottle is clearly labeled as "suitable for microwave ovens" and the material is PP, low-power heating can be used for a short period of time. But it is necessary to ensure that the bottle body is not damaged or decorated with metal, and open the bottle cap to release pressure before heating. The heating time should be controlled within 30 seconds to avoid excessive temperature. immediately transfer to a glass or ceramic container for drinking after heating to reduce plastic contact time.

It is recommended to pour milk into a microwave glass or ceramic cup and heat it, keeping the temperature below 60 degrees Celsius to avoid nutrient loss. Stir every 15 seconds during heating to ensure even heating and avoid local overheating that can damage whey protein. Before heating refrigerated milk, it can be left at room temperature for a moment to reduce the temperature difference. After opening, it is recommended to consume the milk within 24 hours. Choosing pasteurized milk can reduce the microbial risk caused by heating, and lactose intolerant individuals can choose lactose free milk for low-temperature heating.
