Impact of ohmic heating conditions on the behavior of metallized flexible packa...
Marangoni Júnior, Luís; Rodrigues, Rui Miguel Martins; Pereira, Ricardo Nuno Correia; Ito, Danielle; Teixeira, Fábio Gomes; Padula, MarisaThe integrity of packaging material is crucial for understanding the interactions among food, packaging, and processing, as it directly influences packaging performance, the efficacy of processing methods, and the stability of food. This study aimed to evaluate the effects of various ohmic heating (OH) processing conditions on the integrity of PETmet/PE films (PET: polyethylene terephthalate, met: metallization...
Effect of ohmic heating on the structure and properties of flexible multilayer ...
Júnior, Luís Marangoni; Rodrigues, Rui Miguel Martins; Pereira, Ricardo Nuno Correia; Augusto, Pedro Esteves Duarte; Teixeira, Fábio GomesFood-packaging-processing interactions define packaging materials' performance properties and product quality. This study evaluated the effect of ohmic heating (OH) processing and different food simulants on the properties of four multilayer flexible packaging materials (PETmet/PE, PETmet/PP, PET/Al/PE, and PET/Al/PA/PP). OH treatment was applied to the sealed packages containing the simulants using a voltage g...
Starch/PVA-based nanocomposites reinforced with bamboo nanofibrils.
Guimarães Júnior, Mário; Botaro, Vagner Roberto; Novack, Kátia Monteiro; Teixeira, Fábio Gomes; Tonoli, Gustavo Henrique DenzinThis work aimed to evaluate the effect of including different concentrations of bamboo nanofibrils on physical, mechanical, morphological and structural properties of nanocomposites from cassava starch and polyvinyl alcohol (PVA). Nanocomposites were prepared with blends of starch/PVA and nanofibrils of bamboo. Chemical pre-treatments and mechanical defibrillation were used to obtain the nanofibrils. The mixtur...
