Because the air contains bacteria, the nutrient content in the milk powder is more adequate, the baby’s immune system is lower, the brewed milk powder at room temperature for about 3~4 hours after it can not be drunk.
Generally the air will float certain bacteria, in the milk powder brewing may be mixed with certain bacteria into it, because the milk powder brewing contains rich nutrients, such as carbohydrates, proteins, fats, etc., it is relatively easy to cause bacterial growth, which leads to the loss of nutrients in the milk powder, and even produce toxic and harmful substances.
Children’s resistance is relatively weak, for the bacterial attack is more sensitive, so generally after the brewing of the milk powder, room temperature about 3 ~ 4 hours can not drink, and the higher the temperature, the shorter the preservation time.
