Abstract
Background: Aflatoxin B1 is a secondary toxic metabolite that is produced by several Aspergillus species. This study was conducted to determine the presence of aflatoxin in tomato paste samples. Methods: A total of 30 tomato paste were analyzed for Aflatoxin B1 contamination via HPLC-FLD. Analyte extraction was done by dispersive liquid-liquid microextraction. Results: The limit of detection (LOD) and limit of quantitation (LOQ) were 0.14 and 0.44 µg/kg respectively. Recovery ranged was between 91 to 94 %. The results showed all of the samples were contaminated with Aflatoxin B1 and the average concentration was 1.1 + 0.02 µg/kg. The amount of aflatoxin B1 in 6 samples was higher than the European :union: limit. Conclusion: The proposed method was successfully applied to the analysis of tomato paste samples with quantitative results. The main advantages of the developed method are the simplicity of operation, the rapidity to achieve a very high sample throughput and low cost.
