Abstract: According to the relevant requirements and methods in the "Guidelines for Stability Study of Infant Formula Milk Powder Products (Trial)", investigated the nutrient attenuation of infant formula milk powder in accelerated and long-term tests. The results showed that macronutrients and fatty acids were relatively stable in accelerated and long-term tests, with a decay rate of less than 5%. Vitamins did not show significant attenuation in accelerated and long-term tests, with a decay rate of less than 10%. The iodine index in minerals showed significant attenuation in the accelerated test, with a maximum attenuation rate of 11.37%. Other mineral indicators did not show significant attenuation. The optional components were relatively stable in accelerated and long-term tests, with a decay rate of less than 5%. This study can provide scientific reference for the formula design of infant formula milk powder, selection of packaging materials, determination of storage conditions and shelf life, etc.
