Optimised model microcapsules of Arabic gum and gelatin a for functional cosmet...
Kessler, Júlia C.; Martins, Isabel M.; Manrique, Yaidelin A.; Lopes, José Carlos B.; Rodrigues, Alírio; Barreiro, M.F.; Dias, Madalena M.Microcapsules were developed using Arabic gum and gelatin A through complex coacervation, employing both batch and continuous production methods. Ingredients were chosen to encapsulate diverse hydrophobic core materials with functional properties tailored for cosmetic applications, such as those found in commercial hydrating creams, aiming to enhance their performance through microencapsulation. The formulation...
Literature Review on Single and Twin-Screw Extruders Design for Polymerization ...
Delvar, Elham; Oliveira, Inês; Brito, Margarida S. C. A.; Silva, Cláudia G.; Santamaria-Echart, Arantzazu; Barreiro, M.F.; Santos, Ricardo J.This work presents a comprehensive review of the evolution in modeling reactive extrusion (REx), tracing developments from early analytical models to advanced computational fluid dynamics (CFD) simulations. Additionally, it highlights the key challenges and future directions in this field. Analytical models to describe the velocity profiles were proposed in the 1950s, involving certain geometrical simplificatio...
Solid dispersions as effective curcumin vehicles to obtain k-carrageenan functi...
Rezende, Stephany; Santamaria-Echart, Arantzazu; Almeida, Heloísa H.S.; Marcet, Ismael; Carpintero, Maria; Rendueles, Manuel; Lopretti, MarySynthetic packaging materials offer cost efficiency and performance but pose environmental risks. This study explores sustainable alternatives by developing k-carrageenan (KC) films functionalized with curcumin, using solid dispersions (SDs) to improve curcumin's compatibility, addressing the challenge of incorporating hydrophobic functionalities into hydrophilic film matrices. Films with varying curcumin conte...
Application of the FTIR technique as a non‐invasive tool to discriminate Portug...
Lamas, Sandra; Ruano, Daniela Filipa Magalhães; Dias, Francisco; Barreiro, M.F.; Pereira, J.A.; Peres, António M.; Rodrigues, NunoThree Portuguese olive oils with PDO (‘Azeite do Alentejo Interior’, ‘Azeites da Beira Interior’ and ‘Azeite de Trás-os-Montes’) were studied considering their physicochemical quality, antioxidant capacity, oxidative stability, total phenols content, gustatory sensory sensations and Fourier transform infrared (FTIR) spectra. All oils fulfilled the legal thresholds of EVOOs and the PDO's specifications. Olive oi...
Patente Nacional Nº 118006 - Método de produção de goma xantana com bagaço húmi...
Crugeira, Pedro Jorge Louro; Barreiro, M.F.; Almeida, Heloísa Helena Scorsato de; Pires, Marcella Golini; Rafael, Helder MartinsO presente invento refere-se a um processo de produção de goma xantana, a partir da cepa de Xanthomonas campestris atcc 33913, com o uso do bagaço húmido da azeitona, proveniente da extração do azeite em sistema contínuo de duas fases. O método utiliza o bagaço húmido de azeitona pasteurizado até uma concentração de 45% suplementado com 2,0% de sacarose para meio de produção. Os polifenóis, poli...
Disclosing the potential of Cupressus leylandii A.B. Jacks & Dallim, Eucalyptus...
Almeida, Heloísa H.S.; Crugeira, Pedro Jorge Louro; Amaral, Joana S.; Rodrigues, Alírio; Barreiro, M.F.Antimicrobial resistance is a major global health concern, threatening the effective prevention and treatment of infections caused by microorganisms. These factors boosted the study of safe and green alternatives, with hydrosols, the by-products of essential oils extraction, emerging as promising natural antimicrobial agents. In this context, four hydrosols obtained from Cupressus leylandii A.B. Jacks & Dallim,...
Nano-hydroxyapatite Pickering emulsions as edible mayonnaise-like food sauce te...
Relvas, Maria Eduarda; Ghirro, Larissa Camargo; Martins, Isabel M.; Lopes, José Carlos B.; Dias, Madalena M.; Barreiro, M.F.; Ribeiro, AndreiaPickering emulsions have the potential to enhance product stability and provide opportunities to create functional solutions that align with labelling requirements. The present work aims to develop Pickering emulsions stabilised by nano-hydroxyapatite (n-HAp) particles to replace traditional mayonnaises. The study addresses the effect of n-HAp solid particle concentration (5–15 wt%) and oil-water ratio (50:50, ...
Response surface methodology applied to ultrasound-assisted extraction of raspb...
Plasencia, Paula; Carocho, Márcio; Heleno, Sandrina A.; Finimundy, Tiane C.; Barreiro, M.F.; García, Pablo A.; Barros, LillianDue to their high nutritional value, berries production has increased, but this inevitably leads to the accumulation of bioresidues. To prevent this, leaves and other aerial components of berry plants can be converted into valuable ingredients for cosmetics applications due to their unique chemical composition and functional properties. Ultrasound-assisted extraction methodology is an efficient technique to obt...
Unlocking the Potential of Hydrosols: Transforming Essential Oil Byproducts int...
Almeida, Heloísa H.S.; Fernandes, Isabel P.; Amaral, Joana S.; Rodrigues, Alírio; Barreiro, M.F.The global demand for sustainable and non-toxic alternatives across various industries is driving the exploration of naturally derived solutions. Hydrosols, also known as hydrolates, represent a promising yet underutilised byproduct of the extraction process of essential oils (EOs). These aqueous solutions contain a complex mixture of EO traces and water-soluble compounds and exhibit significant biological acti...
Evaluating the potential of natural polymers for water-dispersible curcumin-bas...
Rezende, Stephany; Ferreira, Olga; Santamaria-Echart, Arantzazu; Dias, Madalena M.; Barreiro, M.F.Solid dispersion (SD) technology, a strategy through which a hydrophobic compound is molecularly dispersed into a hydrophilic carrier, is raising interest in food applications to surpass natural colourants’ low water solubility. Motivated by the importance of using natural solutions, five natural polymers (k-carrageenan (KC), maltodextrin (MD), Arabic gum (AG), potato starch (PS), and pectin (PC) were evaluated...
