The duration of 42 ℃ constant temperature of milk powder depends on many factors, including the composition of milk powder, ambient temperature, performance of heating equipment, etc. In general, the following suggestions can be referred to:
1. Composition of milk powder: The composition of different milk powder is different. Some milk powder is easy to deteriorate, and some can be stored at a constant temperature of 42 ℃ for a longer time. It is recommended to check the instructions on the package before using the milk powder to understand the storage time and conditions of the milk powder.
2. Ambient temperature: The higher the ambient temperature, the shorter the storage time of milk powder. In summer or high temperature environment, it is recommended to shorten the storage time of milk powder as far as possible.
3. Performance of heating equipment: the performance of heating equipment will also affect the storage time of milk powder. If high-quality heating equipment is used, the precision of constant temperature can be kept higher, thus extending the storage time of milk powder.
In general, it is recommended to keep the milk powder at a constant temperature of 42 ℃ for no more than 2 hours. If it exceeds this time, it is recommended not to eat it, so as not to affect health. In addition, it is recommended to check carefully before using the milk powder to ensure that there is no deterioration or odor. In case of any abnormality, it is recommended not to eat.
