Novas perspetivas na produção de embalagens alimentares - Bibliografia
A indústria alimentar é uma das maiores utilizadoras de plásticos, sobretudo sob a forma de embalagens, mas também como películas que revestem os alimentos e os protegem. Contudo, com as novas diretivas europeias e mundiais que visam reduzir e preferencialmente eliminar o uso de plásticos, a indústria e a comunidade científica terão que se reinventar para desenvolver tecnologias que permitam com eficiência proteger alimentos e, ao mesmo tempo, não constituírem fontes de poluição ou contaminação para os ecossistemas.
Assim, terão que ser tecnologias biodegradáveis e com pouco ou nenhum impacto negativo. Um longo caminho foi já trilhado, havendo alternativas que parcialmente substituem os plásticos convencionais, mas que ainda não conseguem competir em termos económicos e também a nível das propriedades físicas. Ainda assim, o aparecimento de bioplásticos abre oportunidade para se introduzirem nestes biopolímeros compostos naturais que irão ajudar a conservar alimentos, criando uma base para futuras inovações. A próxima década será determinante para a reinvenção dos bioplásticos.
