Resumen
This study investigated the occurrence of aflatoxin B 1, B 2, G 1 and G 2 and ochratoxin A in chocolate marketed in Brazil. A hundred and twenty-five samples of powdered, bitter, dark, milk and white chocolate were evaluated for mycotoxins. Ochratoxin A was the most common mycotoxin in the evaluated samples, contaminating 98% of the purchased chocolate. A co-occurrence of aflatoxins was observed in 80% of all samples evaluated. The bitter, dark and powdered chocolate samples had the largest presence of aflatoxins. On average, the highest levels of ochratoxin A were found in powdered, dark and bitter chocolate, respectively: 0.39; 0.34 and 0.31μg/kg. Bitter, powdered and dark chocolate had the highest aflatoxin content; an average of 0.66, 0.53 and 0.43μg/kg, respectively. This is the first report of co-occurrence of ochratoxin A and aflatoxins in chocolate. The consumption of chocolate with high levels of cocoa in the formulation has been stimulated due to health benefits attributed to some cocoa components but on the other hand, these high cocoa content products tend to have the highest amount of aflatoxins and ochratoxin A. To guarantee a safe consumption of chocolate, there should be a continuous monitoring of both ochratoxin and aflatoxin and more studies attempting to understand the dynamics involving mycotoxin-producing fungi and mycotoxin production in cocoa need to be carried out with the aim of preventing mycotoxin accumulation in this commodity. © 2011 Elsevier Ltd. 26 1 36 41 Bonvehi, J.S., Occurrence of ochratoxin A in cocoa products and chocolate (2004) Journal of Agricultural and Food Chemistry, 52, pp. 6347-6352 Boudra, H., Le Bars, P., Le Bars, J., Thermostability of ochratoxin A in wheat under two moisture conditions (1995) Applied and Environmental Microbiology, 61, pp. 1156-1158 Brera, C., Debegnach, F., De Santis, B., Iafrate, E., Pannunzi, E., Berdini, C., Ochratoxin A in cocoa and chocolate products from the Italian market: occurrence and exposure assessment (2011) Food Control, 22, pp. 1663-1667 Buchanan, R.L., Lewis, D.F., Caffeine inhibition of aflatoxin synthesis: probable site of action (1984) Applied and Environmental Microbiology, 47 (6), pp. 1216-1220 Burdaspal, P.A., Legarda, T.M., Ocratoxina A en distintos tipos de chocolate y preparados de cacao en polvo comercializados en Espana y en otros paises extranjeros (2003) Alimentaria, 347, pp. 143-153 (2003) Codex standard for chocolate and chocolate products, , CODEX STAN 87-1981, Rev. 1 - 2003, Codex alimentarius Laying down the sampling methods and the methods of analysis for the official control of the levels of aflatoxins in foodstuffs (1998) Official Journal of the European Communities, , Commission Directive 1998/53/EC Laying down the sampling methods and the methods of analysis for the official control of the levels of ochratoxin A in foodstuffs (2002) Official Journal of the European Communities, , Commission Directive/2002/26 EC Copetti, M.V., Iamanaka, B.T., Pereira, J.L., Fungaro, M.H., Taniwaki, M.H., Aflatoxigenic fungi and aflatoxin in cocoa (2011) International Journal of Food Microbiology, 148 (2), pp. 141-144 Copetti, M.V., Pereira, J.L., Iamanaka, B.T., Pitt, J.I., Taniwaki, M.H., Ochratoxigenic fungi and ochratoxin A in cocoa during farm processing (2010) International Journal of Food Microbiology, 143, pp. 67-70 Christmann, E.P., Badgett, J.L., (2009) Interpreting assessment data: Statistical techniques you can use, , NSTA Press Engel, G., Ochratoxin A in sweets, oil seeds and dairy products (2000) Archiv fur Lebensmittelhygiene, 51, pp. 81-128 Ferraz, M.M., Farah, A., Iamanaka, B., Perrone, D., Copetti, M.V., Marques, V.X., Kinetics of ochratoxin destruction during coffee roasting (2010) Food Control, 21, pp. 872-877 Gilmour, M., Lindblom, M., Management of ochratoxin A in the cocoa supply chain: a summary of work by the CAOBISCO/ECA/FCC working group on ochratoxin A (2008) Mycotoxins: Detection methods, management, public health and agricultural trade, pp. 231-243. , CABI, Wallinford, J.F.
