Phytochemical profile and anticholinesterase and antimicobial activities of sup...
Silva, Filipa; Martins, A.; Salta, J.; Neng, N. R.; Nogueira, J.; Mira, Delfina; Gaspar, Natália; Justino, Jorge; Grosso, C.; Urieta, J. S.Winter savory Satureja montana is a medicinal herb used in traditional gastronomy for seasoning meats and salads. This study reports a comparison between conventional (hydrodistillation, HID, and Soxhlet extraction, SE) and alternative (supercritical fluid extraction, SFE) extraction methods to assess the best option to obtain bioactive compounds. Two different types of extracts were tested, the volatile (SFE-9...
Properties of chemically modified gelatin films
Carvalho,R. A. de; Grosso,C. R. F.Edible and/or biodegradable films usually have limited water vapor barriers, making it difficult to use them. Thus, the objective of this work was to evaluate the effect of a chemical reticulation treatment with formaldehyde and glyoxal on the mechanical properties, water vapor permeability, solubility and color parameters of gelatin-based films. Formaldehyde and glyoxal were added to the filmogenic solution in...
Characterization of composite biofilms of wheat gluten and cellulose acetate ph...
Fakhouri,F. M.; Tanada-Palmu,P. S.; Grosso,C. R. F.The objective of this research was to develop and characterize composite biofilms produced using wheat gluten and cellulose acetate phthalate. Biofilms act as barriers to moisture and oxygen diffusion through the film. The films were prepared with different thicknesses and component concentrations and were analyzed for water vapor and oxygen permeabilities, water and acid solubilities and mechanical properties....
