Feasibility of incorporating recycled multilayer LDPE/EVOH films into flexible ...
Barros, Carolina Lemos; Carneiro, O. S.; Machado, A. V.Multilayer films are widely used in the food industry because they allow the combination of properties of different materials to increase product shelf life without sacrificing product value. Despite the associated benefits, these films are difficult to recycle due to material immiscibility and difficult layer separation. Thus, the purpose of this research is to investigate the feasibility of incorporating recy...
Development of high-performance recyclable films for food packaging
Barros, Carolina LemosAlgumas embalagens de plástico para produtos alimentares permitem o aumento do prazo de validade dos alimentos, diminuindo o seu desperdício e tornando-os mais acessíveis a toda a população. Estas embalagens, de um modo geral, combinam diferentes tipos de materiais em filmes coextrudidos ou laminados, permitindo assim melhorar as propriedades estéticas e funcionais (mecânicas e/ou de barreira), mas dificultando...
PLA films loaded with green tea and rosemary polyphenolic extracts as an active...
Andrade, Mariana A.; Barbosa, Cássia H.; Cerqueira, Miguel A.; Azevedo, Ana Gabriela; Barros, Carolina Lemos; Machado, A. V.; Coelho, AnabelaIn the present study, RE presented higher antioxidant capacity and higher content of total phenolic compounds than GTE. While the main phenolic compounds identified in RE were carnosic acid, carnosol and rosmarinic acid, in GTE catechins, rutin and gallic acid were the main identifies compounds. Extracts were incorporated into PLA active films, followed by the evaluation of its properties. The potential of the ...
Active flexible films for food packaging: a review
Azevedo, Ana G.; Barros, Carolina Lemos; Miranda, Sónia; Machado, A. V.; Castro, Olga; Silva, Bruno; Saraiva, Margarida; Silva, Ana SanchesActive food packaging is a dynamic area where the scientific community and industry have been trying to find new strategies to produce innovative packaging that is economically viable and compatible with conventional production processes. The materials used to develop active packaging can be organized into scavenging and emitting materials, and based on organic and inorganic materials. However, the incorporatio...
