Abstract
Un sensor para detectar la presencia de bacterias en un alimento perecedero incluye una solucion sensible al pH de azul bromotimol y rojo metilo mezclada con un álcali, lo que da lugar a un valor de pH y al cambio de un color generalmente verde a un color generalmente anaranjado en respuesta a la exposicion a una concentracion de dioxido de carbono. La solucion está envasada en un envase permeable a los gases utilizando una película de TPX (PMP), lo que da lugar a la difusion eficaz del dioxido de carbono a través del envase. el nivel de pH cae al entrar en contacto el dioxido de carbono ácido con la solucion como resultado de la formacion de ácido carbonico, lo que hace que la solucion sea un indicador de la concentracion de dioxido de carbono y, por ende, un indicador del desarrollo de bacterias.A sensor for detecting the presence of bacteria in a perishable food includes a pH-sensitive solution of bromothymol blue and methyl red mixed with an alkali, which results in a pH value and the change from a generally green color to a generally orange in response to exposure to a concentration of carbon dioxide. The solution is packaged in a gas permeable container using a TPX film (PMP), which results in the effective diffusion of carbon dioxide through the container. The pH level falls when the acidic carbon dioxide comes into contact with the solution as a result of the formation of carbonic acid, which makes the solution an indicator of the concentration of carbon dioxide and, therefore, an indicator of the Bacterial development
