Coffee and cocoa are consumed worldwide and have gained international recognition. Many producers cultivate these crops using pesticides, or the soils in which they are grown are contaminated with heavy metals that can be absorbed by the plants. For this reason, it was necessary to quantify the concentrations of lead, cadmium, and arsenic in cocoa beans (Theobroma cacao L.) and coffee beans (Coffea arabica L.) from the Jaén – Cajamarca region, during the period from February to July 2018. A total of sixteen samples were collected and analyzed using the atomic absorption method associated with graphite furnace and FIAS hydride generation. The results showed that in coffee beans from the Jaén – Cajamarca region, the average concentrations were 0.11 µg/g for arsenic, 0.11 µg/g for cadmium, and 1.18 µg/g for lead. Most of the analyzed samples did not exceed the maximum values permitted by MERCOSUR regulations, making them suitable for consumption. In cocoa beans from the Jaén – Cajamarca region, the average concentrations were 0.08 µg/g for arsenic, 0.07 µg/g for cadmium, and 0.10 µg/g for lead. When compared with the permissible values established by the Codex Alimentarius, the concentrations of each metal found indicated that more than 60% of the samples are admissible for human consumption.

La intervención nutricional es de importancia para medir la fuerza de presión manual por dinamometría y determinar si esta técnica puede identificar el riesgo de mortalidad en pacientes en hemodiálisis, el presente trabajo tuvo como objetivo identificar la sensibilidad de esta prueba para determinar el riesgo de mortalidad. La pregunta clínica fue: ¿Es la dinamometría un predictor del riesgo de mortalidad en pacientes en TRR por Hemodiálisis? Se utilizó la metodología Nutrición Basada en Evidencia (NuBE). La búsqueda de información se realizó en PUBMED, MEDLINE, SCIELO, SCOPUS, SCIENCE DIRECT, encontrando 24 artículos, que han sido evaluados por la herramienta para lectura crítica CASPE, seleccionando al final el trabajo de investigación titulado “ La fuerza de presión manual como predictor de la mortalidad por todas las causas en pacientes con enfermedad renal crónica sometidos a diálisis: un meta-análisis de estudios de cohorte prospectivos”, el cual posee un nivel de evidencia I y Grado de Recomendación fuerte . Se concluyó que la medición de HGS nos brinda un dato útil sobre la fuerza muscular en los pacientes y que podría ser una herramienta simple y confiable para predecir la mortalidad en pacientes con ERC sometidos a diálisis.

Evaluación del nivel de ocratoxina A en las fases de post cosecha de Theobroma cacao L. “cacao trinitario” y chocolates artesanales en el distrito de Pisana – San Martin, 2018

Ochratoxin A is a nephrotoxic and carcinogenic mycotoxin capable of causing harmful effects to humans and animals, and it is found in many foods, including cocoa and its derivatives. The objective of this study was to determine and quantify the levels of ochratoxin A in Theobroma cacao L. in its post-harvest stages and in artisanal chocolates from the district of Pisana, San Martin. The methodology involved an extraction process using immunoaffinity columns and quantification by High-Performance Liquid Chromatography (HPLC). The cacao and artisanal chocolate samples were collected in the Pisana district of the San Martin department in 2018. Detection was performed by fluorescence, at an excitation wavelength of 333 nm and an emission wavelength of 460 nm. The results from the stored cacao samples showed values of 0.938 and 0.935 ppb of ochratoxin A for injection 1 and injection 2, respectively. We concluded that the values from the cacao samples did not exceed the detection limit of 0.798 µg/kg and that both injections did not surpass the limits permitted by international legislation. This study highlights the importance of the traceability of potentially harmful compounds in the production chain of high-demand foods, both nationally and internationally, to ensure their quality.
