Simultaneous vehiculation of curcumin and riboflavin in bigels produced through...
Clímaco, Gabrielli Nunes; Gonçalves, Raquel Filipa Silva; Fernandes, Jean Michel; Pinheiro, Ana Cristina; Vicente, A. A.; Fasolin, Luiz HenriqueThe influence of curcumin (model hydrophobic compound) and riboflavin (model hydrophilic compound) on the structure and physicochemical properties of bigels produced with cold-set whey protein isolates (WPI) was assessed. The hydrogel phase was produced with WPI (11% w/v) while for the oleogel phase, sunflower oil and glycerol monostearate (GM) (10% w/v) were used. Curcumin (0.03 mg/mL) was added to the oil pha...
Introductory Note
Pequito, Paula; Pinheiro, Ana Cristina; Silva, Brigite; Craveiro, Clara; Daniela, Gonçalves; Neves, Ivone; Irene, Cortesão; Medeiros, PaulaThe history of Higher School of Education of Paula Frassinetti walks alongside with a constant concern about children’s development and education. It is in acontext identified by a permanent need for questioning that the “Childhood Week” (May 2021) emerged. This event was an opportunity for meetings and debates among professionals from different countries, dealing with issues that are raised today in Childhood ...
Unravelling nanoemulsions vs excipient nanoemulsions: formulation optimization,...
Fernandes, J. M.; Araújo, J.; Gonçalves, Raquel F. S.; Vicente, A. A.; Pinheiro, Ana CristinaThe consumption of functional foods incorporating bioactive compounds as a way to promote a healthier lifestyle has gained particular interest in research community and food industry. Firstly, 3D printing has been used in food manufacturing as a novel technology in this field to improve food sensorial properties (e.g., appearance and texture) as well as nutritional/functional content. Secondly, since bioactive ...
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 ...
Characterization and Genomic Analysis of a New Phage Infecting Helicobacter pylori
Ferreira, Rute; Sousa, Cláudia; Gonçalves, Raquel F.S.; Pinheiro, Ana Cristina; Oleastro, Mónica; Wagemans, Jeroen; Lavigne, Rob; Figueiredo, CeuHelicobacter pylori, a significant human gastric pathogen, has been demonstrating increased antibiotic resistance, causing difficulties in infection treatment. It is therefore important to develop alternatives or complementary approaches to antibiotics to tackle H. pylori infections, and (bacterio) phages have proven to be effective antibacterial agents. In this work, prophage isolation was attempted using H. p...
An in vitro fermentation model to study the impact of bacteriophages targeting ...
Pinto, Graça; Shetty, Sudarshan A.; Zoetendal, Erwin G.; Gonçalves, Raquel F. S.; Pinheiro, Ana Cristina; Almeida, Carina Manuela FernandesLytic bacteriophages are considered safe for human consumption as biocontrol agents against foodborne pathogens, in particular in ready-to-eat foodstuffs. Phages could, however, evolve to infect different hosts when passing through the gastrointestinal tract (GIT). This underlines the importance of understanding the impact of phages towards colonic microbiota, particularly towards bacterial families usually fou...
Unveiling the impact of STEC infecting phages on the colon microbiota using an ...
Pinto, Graça; Shetty, Sudarshan; Zoetendal, Erwin G.; Gonçalves, Raquel Filipa Silva; Pinheiro, Ana Cristina; Almeida, Carina Manuela Fernandes(Bacterio)phages are considered safe for humans consumption, being regard as excellent biocontrol tools to prevent foodborne pathogens spread. Phages major advantage is their inherent specificity towards a bacterial species, yet some reports have shown phages ability to evolve to infect different hosts when transiting the gastrointestinal tract (GIT). And so, it is of extreme importance to understand the safety...

Tackling older adults malnutrition through the development of tailored food pro...
Fernandes, J. -M.; Araújo, J.; Vieira, J.; Pinheiro, Ana Cristina; Vicente, A. A.Background The global population is ageing. Elderly population has surpassed the number of children under 5 years of age, making older adults the fastest-growing age group. The life expectancy increase is the result of scientific, technological and social advances made during recent decades. However, the increase in life expectancy is not accompanied by a healthy ageing, since older adults undergo several physi...
In vitro digestion simulation of medium chain fatty acids using static and dyna...
Pereira, Ericsem; Fernandes, Jean Michel; Gonçalves, Raquel Filipa Silva; Pinheiro, Ana Cristina; Duarte, Maria Salomé Lira; Alves, M. M.Food biophysics research has more recently focused on understanding the behavior of foods within the human gastrointestinal (GI) tract. In vitro models allow the screening of foods and are helpful for better understanding digestive kinetics. They can be used to evaluate the metabolic properties of macronutrients such as medium-chain fatty acids (MCFAs). In this work, a dynamic GI model system [Pinheiro et al., ...
