In this study, we aimed to identify and quantify aflatoxins (AFs) (AFB 1 , AFB 2 , AFG 1 , and AFG 2 ) by liquid chromatography and to validate the methodology in 3 types of chili peppers, "Ancho", "Guajillo" and "Piquín" which are the most frequently consumed chili peppers in the 16 boroughs of Mexico City. As a separate aim, we analyzed the AFs in some chili pepper samples from India, Turkey and South Africa to determine whether the amount of AF contamination in chili peppers represents a health risk. Sixty-four compound samples of the three types of chili peppers in 48 markets of Mexico City and nine foreign samples from India, Turkey and South Africa were analyzed. The validation of the method for analyzing AFs included selectivity, lineality, recovery percentage and limits of detection and quantification. The average AF concentrations (µg kg -1 ) for "Ancho" chili pepper were AFB 1 (1.46), AFB 2 (0.15), AFG 1 (1.28), AFG 2 (2.08) and total aflatoxins (AFt) (3.49), which exhibited the highest contamination. The average AF concentrations (µg kg -1 ) for "Guajillo" hot pepper were AFB 1 (0.53), AFB 2 (0.08), AFG 1 (0.40), AFG 2 (0.85), and AFt (0.92). The average AF concentrations (µg kg -1 ) for "Piquín" chili pepper were AFB 1 (1.44), AFB 2 (0.10) AFG 1 (1.57), AFG 2 (1.09) and AFt (3.14). The 8 samples from foreign countries had average AF concentrations (µg kg -1 ) of AFB 1 (0.7), AFB 2 (0.2), AFG 1 (0.7), AFG2 (1.1), and AFt (1.8 µg kg -1 ). Most of the chili peppers exhibited a significant difference in relation to their origin in Mexico City, with the exception of AFG 2 in "Guajillo" chili pepper. The Mexican chili peppers had more complete sampling for the AFs than the few samples analyzed from Turkey, India and South Africa, which did not represent the whole country.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
