Abstract

LOS ALIMENTOS PUEDEN SER EMPAQUETADOS Y CONSERVADOS DURANTE PERIODOS EXTENDIDOS USANDO POLIMEROS INTELIGENTES CONFORMADOS COMO ENVASES PARA ALIMENTOS QUE TIENEN UNAS PERMEABILIDADES AL GAS ESPECIFICAS Y VARIABLES. LOS POLIMEROS USADOS EN LA FORMACION DE LOS ENVASES PARA ALIMENTOS SON INTELIGENTES YA QUE TIENEN UNAS PERMEABILIDADES QUE PUEDEN SER CAMBIADAS DE FORMA RADICAL Y REVERSIBLE MEDIANTE CAMBIOS RELATIVAMENTE PEQUEÑOS EN LA TEMPERATURA. USANDO TIPOS Y FORMULACIONES DIFERENTES DE POLIMEROS Y VARIAS TEMPERATURAS, ES POSIBLE CREAR UN MEDIO AMBIENTE DENTRO DEL ENVASE PARA ALIMENTOS QUE SE AJUSTE A LA RESPIRACION DE LOS ALIMENTOS DE MANERA QUE SE PRESERVE DE LA MEJOR FORMA EL COLOR, LA CALIDAD Y LA VIDA MEDIA DEL ALIMENTO. LOS POLIMEROS SON POLIMEROS CRISTALIZABLES DE CADENA LATERAL DISEÑADOS Y FORMULADOS PARA SUMINISTRAR UN MATERIAL QUE SEA SUBSTANCIALMENTE IMPERMEABLE A UN GAS COMO EL OXIGENO, EL DIOXIDO DE CARBONO O EL VAPOR DE AGUA A UNA TEMPERATURA POR DEBAJO DE UN PUNTO DE TRANSICIONDE FASE DADO IMPERMEABLES A LOS MISMOS GASES A UNA TEMPERATURA POR DEBAJO DE ESE PUNTO.
