ABSTRACT / САЖЕТАК:

Iodide in infant food is a crucial micronutrient for infants’ development, as they are born with small amounts of stored intrathyroidal iodine. Human milk and infant formula are the primary sources of iodide for newborns, providing this essential element for both term and premature infants. This study aimed to monitor the concentration of iodide in infant food for term and premature infants, including human milk, infant formula, and cow milk. An iodide-ion-selective electrode was used to detect the iodide concentration in infant food samples. Results showed that premature colostrum and infant formula have the highest iodide concentration compared to mature milk samples. Over time, iodide levels undergo a significant decrease during lactation. Since premature infants are more vulnerable, their need for sufficient iodine for growth is higher, which is consistent with the obtained results.
