Impregnation of cinnamaldehyde into cassava starch biocomposite films using sup...
Souza, Ana Cristina de; Dias, Ana M. A.; Sousa, Hermínio C.; Tadini, Carmen C.In this work, supercritical solvent impregnation (SSI) has been tested for the incorporation of natural compounds into biocomposite materials for food packaging. 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...
Chitosan-based dressings loaded with neurotensin—an efficient strategy to impro...
Moura, Liane I. F.; Dias, Ana M. A.; Leal, Ermelindo C.; Carvalho, Lina; Sousa, Hermínio C. de; Carvalho, EugéniaOne important complication of diabetes mellitus is chronic, non-healing diabetic foot ulcers (DFUs). This study aims to develop and use dressings based on chitosan derivatives for the sustained delivery of neurotensin (NT), a neuropeptide that acts as an inflammatory modulator in wound healing. Three different derivatives, namely N-carboxymethyl chitosan, 5-methyl pyrrolidinone chitosan (MPC) and N-succinyl chi...
