Antioxidantes Naturales en Polmeros: Estabilizacin y aplicacin en el envasado activo (Spanish Edition),Used
Delivery time: 8-12 business days (International)
Dos de las principales reas de investigacin en la actualidad en el campo de los envases alimentarios son: el desarrollo de nuevas tcnicas de envasado capaces de mejorar las propiedades de los alimentos en base a su interaccin con el envase, como los sistemas de envasado activo; y por otra parte, la utilizacin de aditivos de baja toxicidad y en lo posible de origen natural en la formulacin de materiales empleados en contacto con alimentos. Se estudia la incorporacin de tres antioxidantes naturales: carvacrol, hidroxitirosol y tocoferol a polietileno de alta densidad y polipropileno. Se investiga su efectividad en la estabilizacin de ambos polmeros, demostrndose su capacidad para reducir la degradacin termooxidativa de estas poliolefinas. Por lo que se pueden considerar como una alternativa a los aditivos actualmente empleados en formulaciones de materiales plsticos destinados a entrar en contacto con alimentos. Se demuestra tambin que la liberacin controlada de estos compuestos se produce en mayor medida en simulantes grasos, los cuales representan al grupo de alimentos ms sensibles a la oxidacin, perdiendo sus caractersticas organolpticas.
