Abstract
La kiwicha es uno de los pseudocereales que a lo largo de los años ha ocasionado un interés global y así como otros alimentos este es propenso a la contaminación de hongos que superando los limites permisibles causan graves daños a la salud. En este estudio se determinó el efecto del tiempo y caudal de aire en la descontaminación de granos de kiwicha infestados con Aspergillus sydowii sometidos a irradiación UVC en el reactor de lecho fluidizado. Para concretar el efecto de cada factor o su interacción se aplicó un ANOVA, teniendo como resultado que el tiempo y el caudal de aire por si solos no tiene efecto significativo (p > 0.05) mientras que al interactuar los dos factores si se logra un efecto significativo (p < 0.05) para las comparaciones de 60 minutos con 650 – 600 L/h y en 60 minutos con 750 – 650 L/h. Cuando el aire fluye a altas velocidades (hasta 750 L/h), los granos de kiwicha se suspenden dentro del sistema de la mejor manera, lo que podría de ser el caso mitigar la presencia de micotoxinas. El biorreactor tipo lecho fluidizado permite mejorar la interacción de los granos contaminados y los rayos UVC.
ABSTRACT Kiwicha is one of the pseudocereals that over the years has caused global interest and, like other foods, it is prone to contamination by fungi that, exceeding permissible limits, cause serious damage to health. In this study, the effect of time and air flow on the decontamination of kiwicha grains infested with Aspergillus sydowii subjected to UVC irradiation in the fluidized bed reactor was determined. To specify the effect of each factor or its interaction, an ANOVA was applied, resulting in time and air flow alone having no significant effect (p > 0.05), while when the two factors interact, an effect is achieved. significant (p < 0.05) for the comparisons of 60 minutes with 650 – 600 L/h and 60 minutes with 750 – 650 L/h. When air flows at high velocities (up to 750 L/h), kiwicha grains are suspended within the system in the best way, which could potentially mitigate the presence of mycotoxins. The fluidized bed type bioreactor improves the interaction of contaminated grains and UVC rays.
