Homemade versus commercial jarred baby foods with regard to nitrites and nitrates content

Anna Bona

Abstract

This paper presents results of nitrites and nitrates determination in two types of baby foods: commercial products in jars and their homemade conventional counterparts. Nitrites levels in all analyzed samples were below of the detection limit (< 0.9 mg/kg) of applied spectrophotometric method with Griess reagent. Nitrates contents in commercial products ranged: 9.1-38.1 mg/kg while in homemade baby foods levels between 26.6 mg/kg and 118.8 mg/kg were obtained. All the contents of nitrates were lower than the EU legislation maximum limit (200 mg/kg). Comparison of each type of commercial product with its homemade counterpart baby food evidenced significant differences (p < 0.05) in average nitrates levels in favor of the first type. Apart from determining and comparing the levels of nitrates in the baby food samples also risk assessment for an average 6-months old infant to nitrates exposure was conducted. The estimated nitrates intake with a typical portion of 200g of baby food ranged between 6% and 25.7% of acceptable daily intake for commercial and from 18.0% to 80.3% for homemade ones.
