| Abstract | |
Several previous studies on targeted food items using carbon and nitrogen stable isotope ratios in Brazil have revealed that many of the items investigated are adulterated; mislabeled or even fraud. Here, we present the first Brazilian isotopic baseline assessment that can be used not only in future forensic cases involving food authenticity, but also in human forensic anthropology studies. The delta C-13 and delta N-15 were determined in 1245 food items and 374 beverages; most of them made in Brazil. The average delta C-13 and delta N-15 of C-3 plants were -26.7 +/- 1.5 parts per thousand, and 3.9 +/- 3.9 parts per thousand, respectively, while the average delta C-13 and delta N-15 of C-4 plants were -11.5 +/- 0.8 parts per thousand and 4.6 +/- 2.6 parts per thousand, respectively. The delta C-13 and delta N-15 of plant-based processed foods were -21.8 +/- 4.8 parts per thousand and 3.9 +/- 2.7 parts per thousand, respectively. The average delta C-13 and delta N-15 of meat, including beef, poultry, pork and lamb were -16.6 +/- 4.7 parts per thousand, and 5.2 +/- 2.6 parts per thousand, respectively, while the delta C-13 and delta N-15 of animal-based processed foods were -17.9 +/- 3.3 parts per thousand and 3.3 +/- 3.5 parts per thousand, respectively. The average delta C-13 of beverages, including beer and wine was -22.5 +/- 3.1 parts per thousand. We verified that C-C-4 constitutes a large proportion of fresh meat, dairy products, as well as animal and plant-based processed foods. The reasons behind this high proportion will be addressed in this study. (AU) | |
