Cadmium contamination has become an issue of international concern. Cadmium is nephrotoxic, generates damage in the tubular and glomerular function, besides, it causes generalized osteomalacia as well as osteoporosis, and it is considered as a carcinogenic agent by the IARC (International Agency for research of cancer). This toxic element is introduced to the human body through the ingestion of various foods, among these, cocoa and its derivatives, the Codex Alimentarius, established the maximum ranges of cadmium content in chocolate in the regulation (EU) No 488/2014 of January 2019. Colombia, produces fine cocoa of flavor and aroma, a classification granted by the International Cocoa Organization (ICCO), a variety that corresponds to 5% of world demand for cocoa. This research project consists of building a predictive model for the quantitative determination of cadmium in cocoa based on LIBS techniques (Laser Induced Plasma Spectroscopy), and ICP-AES (Inductively Coupled Plasma) and chemometric methods, to use the analytical speed of LIBS, the accuracy of ICP-AES and chemometric methods to predict the concentration of cadmium in cocoa as an alternative method to reduce costs and time in the analytical work.

Implementación de un método de análisis cualitativo y cuantitativo de Cadmio en cacao utilizando las técnicas LIBS (espectroscopia de plasma inducida por láser) y ICP-AES (Espectroscopia de plasma generada por acoplamiento inductivo – Espectroscopia de emisión atómica) y métodos quimiométricos
