Cadmium (Cd) is a naturally occurring heavy metal with no essential biological functions in
humans. It is bioaccumulative and its consumption mainly affects the kidneys, heart, bone system,
among others. Anthropogenic activities have increased the content of Cd in soil around the world,
affecting agri-food production systems. Therefore, the contamination of cocoa (Theobroma cacao
L.) has recently attracted attention,just after the European Union decided to put into effect the
levels of maximum concentrations of Cd in products derived from cocoa. According to data from
MINECO (2015), in Guatemala 96% of the national production of cocoa beans is consumed by
the local market, mainly as table chocolate.
That is why interest arose to determine the presence of cadmium in table chocolate sold in the
main municipal markets of Mazatenango, Suchitepéquez. Using random sampling, in order to
demonstrate that the presence of cadmium in said product is within the permissible limits by the
European Union. A total of 11 samples were analyzed by the atomic absorption spectrophotometry
method with a graphite furnace, the minimum value obtained was 0.04 mg / kg and the maximum
was 0.27 mg / kg, likewise, a arithmetic mean of 0.13 mg / kg and a standard deviation of
0.08 mg/kg. Based on the results, it can be stated that cadmium levels do not exceed the limit of
0.30 mg/kg established by the EU REGULATION 488/2014 for chocolate with a total dry matter
content of cocoa <50%. According to the results obtained, it was concluded that table chocolate is
suitable for human consumption, and the levels of said heavy metal do not represent a barrier to
international trade in the EU for this product. |
