Este estudio tiene por objetivo la evaluación de organismos de ecosistemas acuáticos como Daphnias (pulgas de agua), ante la presencia de contaminantes que provienen de la actividad minera, mediante la aplicación de ensayos biotoxicológicos. Las daphnias se han escogido porque son muy vulnerables a contaminantes y cumplen un papel importantísimo en los ecosiste-mas acuáticos, debido a que consumen otros organismos más pequeños y sirven de alimento a diversos peces. Los ensayos biotoxicológicos fueron aplicados para dos casos en particular, en ambos se obtuvo la concentración letal media (CL50) para daphnias en pruebas cortas (96 h), utilizando para su determinación la curva de análisis Probit. En el primer caso, se evaluó a un solo contaminante (solución de cobre de 1000 ppm), encontrándose que la CL50 es de 3.3 µg/L; en el segundo caso se evaluaron varios contaminantes (...

We assessed the texture profile (TPA), Aw and PH of hot-dog elaborated on the basis of llama meat; We worked with 16 formulations that included different levels of inclusion of egg albumin (AH), Tara Gum (GT) and functional soy Concentrate (CSF). By TPA, cohesiveness, mastication, hardness, gumminess and elasticity were assessed. To evaluate the individual and synergistic effect of the components, the mixture design method was used. It was found that the addition of CSF influenced significantly in hardness (R2 = 0.92) and chewability (r2 = 0.94), while cohesiveness was positively influenced by the greater proportion of GT and AH (r2 = 0.97). On the other hand, the elasticity showed greater magnitude when the proportion of CSF and AH (R2 = 0.90) increased in the mixture. The microbiological barriers of ph and AW were also evaluated, it was observed that the Aw was reduced mainly by CSF an...
