| Abstract An analytical method applying ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was validated for the determination of aflatoxins M2, M1, G2, G1, B2, B1, deoxynivalenol, ochratoxin A, fumonisins B1 and B2, hydrolyzed fumonisins B1 and B2, zearalenone and sterigmatocystin in crackers. The obtained recoveries (70 to 110%) and relative standard deviations (< 13%) were considered satisfactory. Method limits of quantification ranged from 0.20 µg kg-1 (sterigmatocystin) to 12.27 µg kg-1 (deoxynivalenol). The validated method was then applied for mycotoxin determination in 60 cracker samples (cream crackers and water and salt crackers) obtained from the metropolitan area of the state of Rio de Janeiro, RJ. Deoxynivalenol,... |

| Abstract There is a growing concern about health and food safety when it comes to processed food. In the present study, it has been hypothesized that tomato sauces contain high amounts of metals possibly leached from packaging. Concentrations of As, Cd, Pb, Cr, Ni, Sn and Sb were determined by ICP-MS in tomato sauces stored in metallic, plastic, cellulosic and glass packaging. Packaging composition was determined by XRF. This study has also determined Cr and Sn content, by GF AAS, in simulant solutions prepared to be in contact with the four types of packaging. The results showed that there was no significant difference between the concentrations of metals in products stored in different types of packaging (p>0.05), except for Sn and Ni. Canned... |
