β-Cyclodextrin inclusion complexes of combined Moroccan Rosmarinus officinalis,...
El Kharraf, Sara; Farah, Abdellah; EL-GUENDOUZ, Soukaina; Lourenço, João P.; Rosa Da Costa, Ana; El Hadrami, El Mestafa; Machado, Alexandra M.A combined volatile oil (VO) was extracted from Rosmarinus officinalis, Lavandula angustifolia and Citrus aurantium by simultaneous hydro- and steam-distillation, and encapsulated in beta-cyclodextrin by co-precipitation. Response surface methodology (RSM) was used to optimize microencapsulation conditions. The variable recovered powder, VO retention degree, and inclusion efficiency were investigated based on t...
Simultaneous Hydrodistillation-Steam Distillation of Rosmarinus officinalis, La...
El Kharraf, Sara; Faleiro, Maria Leonor; Abdellah, Farah; EL-GUENDOUZ, Soukaina; El Hadrami, El Mestafa; Miguel, MariaInterest in the use of essential oils (EOs) in the biomedical and food industries have seen growing over the last decades due to their richness in bioactive compounds. The challenges in developing an EO extraction process that assure an efficient levels of monoterpenes with impact on biological activities have driven the present study, in which the EO extraction process of rosemary, lavender and citrus was perf...
Encapsulation of Rosmarinus officinalis essential oil in β‐cyclodextrins
El Kharraf, Sara; Farah, Abdellah; El Hadrami, El Mestafa; El‐Guendouz, Soukaïna; Lourenço, João P.; Rosa Da Costa, Ana; Miguel, MariaThe aim of this study was to investigate the encapsulation process of R. officinalis (rosemary) essential oil (REO) in beta cyclodextrin (beta-CD), by co-precipitation, using response surface methodology (RSM), specifically the face-centered central composite design (FCCCD). Solid-to-solid (beta-CD/REO) and liquid-to-liquid (ethanol/water) ratios were selected as independent variables and their influence on the...
Two extraction methods of essential oils: conventional and non-conventional hyd...
El Kharraf, Sara; Farah, Abdellah; G, Miguel; EL-GUENDOUZ, Soukaina; El Hadrami, El MestafaThe traditional extraction of essential oils exposes plant material to high temperatures for hours, which may lead to the production of artifacts, even originating unpleasant odors and loss of quality. In addition, this procedure is energy-consuming, which makes it an expensive method. The present work has been focused on a method that combines hydrodistillation and subsequent extraction with water vapor and vo...
