Abstract: It was studied the nutritional stability of special medical preterm/low birth weight infant formula under accelerated testing at 37℃ ± 2℃, RH75% ± 5% conditions for 6 months. The results showed that the folic acid decay rate of premature infant formula reached 19.12% for 2 months of accelerated testing. The attenuation rate of biotin reached 14.52% after 3 months of acceleration. The decay rates of iodine and selenium were 24.68% and 28.12% respectively at 3 months of acceleration. The decay rate of chlorine at the acceleration of 6 months was 13.47%. The highest attenuation rate of choline during the accelerated test was 21.85%. In this accelerated testing, the nutrients in the preterm formula were relatively stable, and all indicators met the requirements of national food safety standards and relevant regulatory standards such as labeling. Our results provide data reference and basis for related product development design and shelf life formulation.
