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...
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, ...
Vitamin E-loaded hydroxyapatite Pickering emulsions as new product design for f...
Ribeiro, A.; Gonçalves, Raquel Filipa Silva; Pinheiro, A. C.; Manrique, Y. A.; Barreiro, M. Filomena; Lopes, José Carlos B.; Dias, M. MadalenaLipophilic vitamin E is a vital component of human health; however, it degrades quickly and loses bioactivity due to oxidative instability. In this study, vitamin E-loaded Pickering emulsions stabilised by nano-hydroxyapatite (n-HAp) were produced using a static mixer (NETmix), a technique enabling continuous production and droplet size tailoring. Thus, oil-in-water (O/W) emulsions containing vitamin E at a con...
Pickering emulsions based in inorganic solid particles: from product developmen...
Ribeiro, Andreia; Lopes, José Carlos B.; Dias, Madalena M.; Barreiro, M.F.Pickering emulsions (PEs) have attracted attention in different fields, such as food, pharmaceuticals and cosmetics, mainly due to their good physical stability. PEs are a promising strategy to develop functional products since the particles' oil and water phases can act as carriers of active compounds, providing multiple combinations potentiating synergistic effects. Moreover, they can answer the sustainable a...
In vitro digestion and bioaccessibility studies of vitamin E-loaded nanohydroxy...
Ribeiro, Andreia; Gonçalves, Raquel Filipa Silva; Pinheiro, Ana Cristina; Manrique, Yaidelin A.; Barreiro, Maria Filomena; Lopes, José Carlos B.Vitamin E is a lipophilic vitamin playing an essential role in human health. Due to oxidative instability, it presents fast degradation and bioactivity loss. In this study, vitamin E-loaded Pickering emulsions stabilized by nano-hydroxyapatite (n-HAp) were produced using a static mixer (NETmix), a technique enabling continuous production and droplet size tailoring. Thus, oil-in-water (O/W) emulsions containing ...
Development of water-in-oil pickering emulsions from sodium oleate surface-modi...
Ribeiro, Andreia; Manrique, Yaidelin A.; Lopes, José Carlos B.; Dias, Madalena M.; Barreiro, M.F.The stabilisation of water-in-oil (W/O) Pickering emulsions is still a challenge for the scientific community. In this work, sodium oleate (SO) surface modified nano-hydroxyapatite (n-HAp) particles were produced and tested as W/O stabilisers. The modified n-HAp particles presented a wettability dependent on the used SO content, switching from hydrophilic (initial state) to hydrophobic (one SO layer) and back t...
Effect of temperature, pH and ionic strength on hydroxyapatite stabilised Picke...
Ribeiro, Andreia; Manrique, Yaidelin A.; Barreiro, M.F.; Lopes, José Carlos B.; Dias, Madalena M.Oil-in-water (O/W) Pickering emulsions are attracting attention as carriers of lipophilic active compounds with clear advantages over traditional systems. Having in view their effective use it is important to study their stability against environmental stresses impacting manufacture, storage, and application conditions. In this work, hydroxyapatite nanoparticles (n-HAp) Pickering emulsions produced in continuou...

Continuous production of hydroxyapatite Pickering emulsions using a mesostructu...
Ribeiro, Andreia; Manrique, Yaidelin A.; Barreiro, M.F.; Lopes, José Carlos B.; Dias, Madalena M.Emulsions are used in a wide range of applications, including food and cosmetics. Nowadays, the demand for sustainable products has increased with Pickering emulsions emerging as clean alternatives. To achieve the industrial implementation of Pickering emulsions, continuous production and less intensive energy devices are required. In this context, a mesostructured reactor based on an innovative static mixer, N...
Continuous production of melamine-formaldehyde microcapsules using a mesostruct...
Dias, Madalena M.; Moreira, Ana C.G.; Manrique, Yaidelin A.; Martins, Isabel M.; Fernandes, Isabel P.; Rodrigues, Alírio; Lopes, José Carlos B.A mesostructured NETmix reactor was adapted to develop a continuous process to produce microcapsules, focusing on the steps commonly used in batch formulation: the emulsion and cure. Microcapsules were formed through a polycondensation process by coating Miglyol, a skin-hydrating emollient, with melamine-formaldehyde, which is a resistant shell material with surface smoothness. Different recirculation times wer...
