ABSTRACT
Amaranth, quínoa and chía are naturally gluten-free products that may be used in a celiac diet. An ELISA, using R-Biopharm RIDASCREEN gliadin, was used to determine a possible cross contamination with gliadins. Thirty-seven samples of foods with these ingredients were analyzed. Nine samples had levels higher than 20 mglKg, the maximum gluten level established by Codex Alimentarius three of them were cereal bars with the inscription is in TACC and/or ìwithout gluteni, two were cereal bars without inscriptions about gluten content, one was a mixture of ground seeds, others were pop amaranth and quínoa crops (sold at retail) and the last was an amaranth flour which was labeled ifor celiac patients. Twenty-eight remaining samples had gluten content below 20 mglKg. Foods elaborated with amaranth, quínoa and/or chía are suitable for celiac patients. However, the manufacturers must apply good manufacturing practices in all the different steps in gluten-free foodstuff production and celiac patients should not buy these products when they are sold at retail, because of possible cross contamination that can occur at the stores.
RESUMEN
Amaranto, quínoa y chía, por ser naturalmente libres de gluten, pueden ser incorporados en la dieta celíaca. Con el objeto de evaluar una posible contaminación cruzada con gliadinas no permitidas, se analizaron 37 alimentos con estos ingredientes mediante un enzi-moinmunoensayo utilizando RIDASCREEN gliadin de R-Biopharm. Considerando el contenido máximo de gluten establecido por el Codex Alimentarius (20 mg/ Kg), nueve productos superaron la norma tres barras de cereales que declaraban "sin TACC" y/o "no contiene gluten", dos barras de cereales que no tenían ninguna declaración respecto del contenido de gluten, una mezcla de semillas molidas, una muestra de amaranto popeado comprado al detalle, una muestra de semillas de quinoa comprada suelta en un mercado de la provincia de Salta y una muestra de harina de amaranto envasada que declaraba "apto para celíacos". En las veintiocho muestras restantes se evidenció un contenido de gluten inferior a los 20 mg/Kg. Los productos elaborados con amaranto, quínoa y/o chía son seguros para personas con celiaquía; sin embargo, los fabricantes deben implementar buenas prácticas de manufactura en las diferentes etapas de elaboración de alimentos libres de gluten y las personas celíacas no deben consumir alimentos supuestamente aptos que se expenden al detalle, por la posible contaminación cruzada que puede darse en los comercios.
