Abstract
Commercial baby foods are an easy alternative to home-made meals especially for working parents in a
nuclear family therefore it is imperative to determine the nitrate and nitrite content in commercially
available baby foods varieties marketed in Fiji. A total of 108 baby food samples were analyzed for nitrate
and nitrite using our standardized flow injection analysis (FIA) technique with colorimetric detection
technique employing sulfanilamide and N-(1-naphthyl)ethylenediamine dihydrochloride as color
reagents where the samples throughput was 38 h�1. The commercial baby food varieties chosen comprised
of vegetables, cereals, fruits and milk. The study shows that the nitrate content of the baby foods
studied ranges from 2.10 to 220.67 mg kg�1 whereas the nitrite content ranges from 0.44 to 3.67 mg kg�1.
Typical recoveries of spiked nitrate residues ranged from 92% to 106%. The study shows that the average
nitrate content of commercially available baby foods in Fiji descends below the maximum level proposed
by the European Union Legislation.
