Regarding whether the use of hot milk in microwave ovens will destroy the nutritional content of milk, the key lies in the length of heating time. Because the heating speed of the microwave oven is extremely fast, the temperature of the nutrients of the stored milk cannot be too high.
If you use a microwave oven to heat the milk for too long, the protein in the milk will be exposed to high temperatures, which will change from a sol state to a gel state, causing sediments to appear and affect the quality of the milk. The longer the milk is heated, the higher the temperature, and the more serious the loss of nutrients, vitamin C is the most lost, followed by lactose.
A glass of approximately 250 ml of milk, heated with a gas range, is usually cooked at 70°C for 3 minutes.
Then use the microwave oven, about 1 minute.
