Determination of Sulfites in Fruit Juices and Meals for Infants and Toddlers

Abstract

Commercially available foods intended for children (N=14) were inspected for sulfite content, determined by a modified spectrophotometric method upon releasing sulfur dioxide by acid addition. All calculated mean estimates of dietary exposure to sulfites were well below the ADI for both infants and toddlers (0.00–0.47 mg/kg body weight/day and 0.00–0.20 mg/kg body weight/day, respectively). The highest risk was associated with a ready-to-use meal with rice and banana, where consumption of 100 g in infants would account for 67.5% of the ADI, and banana fruit juice (37.1% of ADI).
