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...
Spirulina (Arthrospira platensis) immobilization in calcium-alginate beads can ...
Filomena Barreiro; Silva-Pituco, Samara C.; Aquino, Leandro L.; Dias, Madalena M.C-phycocyanin (C-PC), a water-soluble blue pigment, is the primary phycobiliprotein in Spirulina. In this study, Spirulina was immobilized in calcium-alginate (SAC) beads as an innovative method to recover C-PC in the crosslinking bath while retaining the biomass within the beads. This approach simplifies the separation process and reduces costs. SAC beads were prepared via ionic gelation with alginate and CaCl...
Influence of environmental factors on α-tocopherol levels in Moringa oleifera e...
Kessler, Júlia C.; Manrique, Yaidelin A.; Martins, Isabel M.; Ribeiro, António E.; Rodrigues, Alírio; Barreiro, Filomena; Dias, Madalena M.Moringa oleifera L. extracts (Mo) have attracted attention as a sustainable and effective alternative to synthetic ingredients for cosmetic formulations. The unique and diverse phytochemical profile of the Mo tree enhances the quality and appeal of commercial products, as evidenced by numerous studies and patents. Supercritical carbon dioxide extraction (SFE-CO2) is particularly advantageous for this purpose, o...
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...
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, ...
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...
Developing High-Coloring Natural Systems Using Double Emulsions with Daucus car...
Teixeira, Liandra Gracher; Silva, Samara Cristina; Colucci, Giovana; Santamaria-Echart, Arantzazu; Peres, António M.; Dias, Madalena M.; Barreiro, M.F.Daucus carota L. extract is attracting interest as a natural colorant alternative. However, the presence of anthocyanins (ACNs), which are sensitive to pH changes, limits its application. To tackle this issue, water-in-oil-in-water (W1/O/W2) double emulsions are emerging as innovative solutions. Nevertheless, the problem of reaching robust colorant systems for industrial use still needs to be overcome. One impo...

Teixeira, Liandra Gracher; Silva, Samara Cristina; Colucci, Giovana; Santamaria-Echart, Arantzazu; Peres, António M.; Dias, Madalena M.Anthocyanins (ACNs) are water-soluble bioactive flavonoids found in flowers, roots, leaves, seeds, and stalks. ACNs cover a wide palette of colours, from blue and purple through orange to red1,2. They are used in the food industry (food colourant with E163 code), namely in fruit juice concentrates, nectars, jellies, yoghurts, marmalades, potato chips, ice creams, and soft drinks, replacing the synthetic Red 40 ...
