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...
Impact of the physiological stage on the bioaccessibility of α-tocopherol from ...
Fernandes, Jean Michel; Ménard, Olivia; Cochet, Marie-Françoise; Ossemond, Jordane; Vicente, A. A.; Pinheiro, A. C.; Dupont, DidierAge-related physiological decline negatively impacts nutrient digestion and absorption, making older adults more susceptible to diet-related diseases. Fortified and functional foods are promising strategies to enhance the delivery of nutraceuticals and bioactive compounds. However, understanding how these foods behave under age-specific gastrointestinal conditions is essential. Despite the relevance of in vitro...
Development of 3D-printed foods incorporating riboflavin-loaded whey protein is...
Araújo, João Miguel Fernandes; Fernandes, Jean Michel; Madalena, Daniel Alexandre Silva; Gonçalves, Raquel Filipa Silva; Vieira, Jorge Miguel Magalhães3D printing has emerged as a groundbreaking technology, aiming to enhance sensory attributes and improving nutritional/functional aspects. Simultaneously, nano-delivery systems have emerged as an opportunity to protect bioactive compounds against degradation and improve their bioaccessibility. Therefore, a novel concept is underway, involving the 3D printing of perishable healthy foods previously fortified with...
Development of novel functional thickened drinks enriched with vitamin D3 for t...
Fernandes, Jean Michel; Vieira, Jorge Miguel Magalhães; Gonçalves, Raquel Filipa Silva; Martins, Joana T.; Vicente, A. A.; Pinheiro, A. C.The older adult population is greatly affected by malnutrition. This condition can arise from inappropriate micro and micronutrient intake, as well as due to experienced age-related changes. For instance, a significant number of older adults suffer from dysphagia. Thus, the development of foods with adequate consistency/viscosity are vital for overcome this condition. Within this framework, novel functional thi...
Development and in vitro analysis of tailored functional and excipient foods fo...
Fernandes, Jean MichelAge-related losses of physiological functions in older adults are of utmost importance since they directly impact their metabolism, decreasing their ability to digest and adsorb food nutrients. Functional and excipient foods have been regarded as novel alternatives to improve the extent of delivery of nutraceuticals and bioactive compounds, increasing foods’ nutritional properties by enhancing the stability, bi...
Performance of β-carotene-loaded nanostructured lipid carriers under dynamic in...
Lüdtke, Fernanda Luisa; Fernandes, Jean Michel; Gonçalves, Raquel Filipa Silva; Martins, Joana T.; Berni, Paulo; Ribeiro, Ana P. B.; Vicente, A. A.A better understanding of how emulsifier type could differently influence the behavior of nanostructured lipid carriers (NLC) under the gastrointestinal digestion process, as well as at the cellular level, is of utmost importance for the NLC-based formulations optimization and risk assessment in the food field. In this study, NLC composed by fully hydrogenated soybean and high-oleic sunflower oils were prepared...
Incorporation of curcumin-loaded solid lipid nanoparticles into yogurt:Tribo-rh...
Gonçalves, Raquel Filipa Silva; Fernandes, Jean Michel; Martins, Joana T.; Vieira, Jorge Miguel Magalhães; Abreu, Cristiano S.; Gomes, José R.The incorporation of nanostructures loaded with bioactive compounds into food matrices is a promising approach to develop new functional foods with improved nutritional, health profiles and good sensorial properties. The rheological and tribological properties of yogurt enriched with curcumin-loaded solid lipid nanoparticles (SLN) were evaluated. Also, the TCA solubility index, the bioaccessibility of curcumin ...
Evaluating the in vitro digestion of lipids rich in medium-chain fatty acids (M...
Pereira, Ericsem; Fernandes, Jean Michel; Gonçalves, Raquel F. S.; Pinheiro, A. C.; Duarte, Maria Salomé; Alves, M. M.; Meirelles, Antonio J. A.Investigating the digestion of lipids is paramount for developing new lipid-based products. This work evaluated the gastrointestinal (GI) digestion of medium-chain fatty acids (MCFAs) rich lipids. The dynamic GI in vitro system was used to simulate gastric, duodenal, jejunal, and ileal GI tract portions. Results from the dynamic protocol were compared against static in vitro assays and GC analyses were conducte...
Two-step purification of epilactose produced by cellobiose 2-epimerase from Cal...
Cardoso, Beatriz B.; Fernandes, Jean Michel; Pinheiro, Ana C.; Braga, Adelaide Correia; Silvério, Sara Isabel Cruz; Rodrigues, L. R.Epilactose is a functional sugar that can be produced from lactose using cellobiose 2-epimerase and it is considered a developing prebiotic. In that sense, the development of strategies to produce and purify epilactose is key for its wider use in the food industry. The aim of this work was to establish a food-grade purification strategy suitable to be scaled-up to an industrial level. Firstly, the epilactose wa...
Emerging challenges in assessing bio-based nanosystems’ behaviour under in vitr...
Madalena, Daniel Alexandre Silva; Fernandes, Jean Michel; Avelar, Zita Sofia Barbosa; Gonçalves, Raquel Filipa Silva; Ramos, Óscar L.; Vicente, A. A.The current consumers demand for high quality food products together with the growing awareness regarding the link between health and nutrition has led to the development of novel food products with added functionality. Such functionality can be modulated by adding bio-based nanosystems that can improve the bioaccessibility of bioactive compounds and facilitate nutrient absorption. However, these functional pro...
