Abstract
The active numbers of probiotics in 20 powdered formula products for infants and young children in China were assessed, 18 of which met the international and national standards. The survival rate of Bifidobacteria under various storage conditions after the product is opened was measured. Storage at 37 °C resulted in a significantly higher decay rate than at 4 °C and 25 °C for 14 and 28 days. Results suggest that the probiotic survival rate in powdered formula is negatively correlated with temperature and storage time, whereas the brand and model of the formula have little impact.
