Estimated dietary intake of nitrate and nitrite from meat consumed in Fiji.

To assess the risk posed by meat consumption to the Fiji and Pacific populace, the present study reports nitrate and nitrite in meat. Twelve commercially available meat products, with a total of 210 fresh and processed meat samples, were analysed for nitrate and nitrite by an optimised RP-HPLC technique with isocratic elution using n-octylamine in 20.0% methanol at pH 6.

Flow injection analysis of nitrate and nitrite in commercial baby foods.

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.

Flow injection assessment of nitrate contents in fresh and cooked fruits and vegetables grown in Fiji.

Nitrates form part of the essential chemistry of soils and plants. Thus, plant roots are able to absorb nitrate directly from the soil. It has been discovered that human nitrate intake is mainly from vegetables.
