Cinnamaldehyde, with proved antimicrobial activity against fungi commonly found in bread products, was successfully impregnated on biocomposite cassava starch based materials using supercritical carbon dioxide as solvent. Different process experimental conditions were tested (pressure, impregnation time and depressurization rate) at a fixed temperature (35 °C) in order to study their influence on the amount of impregnated cinnamaldehyde as well as on the morphology of the films. Results showed that all conditions permitted to impregnate antimicrobial active amounts superior to those previously obtained using conventional incorporation methods. Moreover, a significant decrease of the equilibrium water vapor sorption capacity and water vapor permeability of the films was observed after SSI processing which is a clear advantage of the process, considering the envisaged applications. 2014-02-15T00:00:00Z Enzymatic treatment applied as a final stage inE. globuluskraft pulp bleaching Sousa, Joana IT Moura, Ana IG Evtuguin, Dmitry V Carvalho, M Graça VS http://hdl.handle.net/10316/80418 2019-06-02T10:25:31Z 2016-01-01T00:00:00Z Title: Enzymatic treatment applied as a final stage inE. globuluskraft pulp bleaching Authors: Sousa, Joana IT; Moura, Ana IG; Evtuguin, Dmitry V; Carvalho, M Graça VS 2016-01-01T00:00:00Z Settling Suspensions Flow Modelling: A Review Silva, Rui Garcia, Fernando A.
