Investigating bioactive compounds in apple pomace: Potential to develop high ad...
Pascoalino, Liege; Finimundy, Tiane C.; Pires, Tânia C.S.P.; Pereira, Carla; Barros, Lillian; Ferreira, Isabel C.F.R.; Oliveira, BeatrizThis study investigates bioactive compounds in apple pomace (AP) obtained from Malus domestica varieties Granny Smith and Cripps Pink, emphasizing its potential for developing high-added-value products from industrial surplus. Regarding its chemical characterization, AP stood out for its high concentration of dietary fibers (7.1g/100g fw), polyunsaturated fatty acids (linoleic and oleic acids), α-tocopherol (0....
Valorisation of pumpkin by-products: Chemical composition and bioactive propert...
Leichtweis, Maria G.; Molina, Adriana K.; Dias, Maria Inês; Calhelha, Ricardo C.; Pires, Tânia C.S.P.; Pavli, Ourania; Oliveira, BeatrizThis study evaluated the fruit by-products (peels, seeds, and fibrous strands) from 11 pumpkin genotypes cultivated in Greece aiming to valorize them as natural sources of bioactive compounds. Five compounds, including ( )-epicatechin and chicoric acid isomers, were identified in peels, while seeds and fibrous strands mainly contained ( )-epicatechin. Organic acids and tocopherols varied significantly among gen...
Closing the loop: exploring apple pomace as a source of bioactive compounds in ...
Pascoalino, Liege; Barros, Lillian; Barreira, João C.M.; Oliveira, Beatriz; Reis, Filipa S.Apple pomace (AP), the common designation of bio-residues generated during apple processing, holds a vast potential for alternative added-value solutions, particularly by applying new sustainable technologies in the food sector. This review provides an overview of the scientific validation of AP as a suitable source of starting materials for different competitive applications, compatible with circular economy g...
Compositional and Bioactive Differentiation of Opuntia spp. Fruit Varieties by ...
Espírito Santo, Liliana; Pereira, Cláudia S.G.P.; Costa, Anabela S.G.; Almeida, Agostinho; Barreira, João C.M.; Oliveira, Beatriz; Vinha, Ana F.The nutritional, mineral, and bioactive profiles of four Opuntia fruit varieties-Opuntia robusta red variety (OR-RV) and three Opuntia ficus-indica varieties (red, yellow, and green: OFI-RV, OFI-YV, and OFI-GV, respectively)-were characterized to assess their compositional diversity and potential discriminant markers. Standard analytical procedures were applied to determine proximate composition, individual sug...
Innovative Learning in Undergraduate Medical Teaching: Perspective Based on Thi...
Rendas, António; Neuparth, Nuno; Carreiro-Martins, Pedro; Dores, Hélder; Oliveira, Beatriz; Costa, Teresa; Rosado-Pinto, Patrícia; Fonseca, MartaWe reviewed an innovative project in undergraduate medical education, which used problem-based learning and concept maps in pathophysiology teaching. We analyzed publications starting in 1995 and until 2024, to identify factors contributing to its continuity and impact, nationally and internationally.Problem-based learning was based on the methodology developed by Howard Barrows, a founder of the method. In 199...
Recovery of anthocyanins from Eugenia spp. fruit peels: a comparison between he...
Albuquerque, Bianca R.; Pinela, José; Pereira, Carla; Mandim, Filipa; Heleno, Sandrina A.; Oliveira, Beatriz; Barros, LillianNatural colorants have gained increased popularity among consumers and food producers due to their reputation as safer and healthier alternatives to commonly used artificial analogues. These natural pigments can be obtained from by-products resulting from food processing, such as the fruit peels of the Brazilian species Eugenia brasiliensis and Eugenia involucrata, thus contributing to the valorisation and circ...
Exploring the bioactive compounds from berry biowaste: Eugenia involucrata DC. ...
Albuquerque, Bianca R.; Finimundy, Tiane; Pinela, José; Pires, Tânia C.S.P.; Calhelha, Ricardo C.; Vaz, Josiana A.; Corrêa, Rúbia C.G.Aiming at valorising the Eugenia involucrata residue, the present work aimed in investigating the chemical profile and in vitro bioactivities of the residue (EIR) and its individual parts, i.e., seeds (EIS) and peels (EIP). Chromatographic analyses showed that EIP had the highest content of organic acids, tocopherols, and anthocyanins, whereas EIS was the richest in hydrolysable tannins. bis-HHDP-glucoside isom...
Detailed Phytochemical Composition, Cyto-/Hepatotoxicity, and Antioxidant/Anti-...
Bouzaid, Hiba; Espírito Santo, Liliana; Ferreira, Diana M.; Machado, Susana; Costa, Anabela S.G.; Dias, Maria Inês; Calhelha, Ricardo C.Coriander, caraway, and mystical cumin are famous for their aromatic properties and widely used in Moroccan cuisine. The nutritional/phytochemical composition of their seeds (used for food flavoring and preservation) were compared. Their antioxidant, anti-inflammatory, cytotoxic and hepatotoxic effects were also explored. The fat content was similar among the samples (13%), with monounsaturated fatty acids bein...
Metaverso, tendência ou mais um canal de comunicação?
Oliveira, BeatrizEste artigo analisa o universo do Metaverso e examina como está a redefinir as estratégias de comunicação empresariais modernas. O artigo explora as oportunidades e desafios do Metaverso para as marcas, examinando várias formas de utilização deste novo ambiente digital. Existe uma revisão da literatura sobre o Metaverso, além de exemplos concretos de marcas já presentes nesse espaço. Ao longo do texto, são abor...
Melhoria do valor nutricional de microvegetais de acelga através de biofortific...
Pereira, Alexis; Dias, Maria Inês; Oliveira, Beatriz; Pinela, JoséOs sistemas agroalimentares atuais enfrentam grandes desafios associados ao crescimento populacional, às alterações climáticas e ao esgotamento de recursos naturais. Além disso, a deficiência de micronutrientes essenciais, como o selénio, afeta milhões de pessoas em todo o mundo e está associada a sérios problemas de saúde. As alterações climáticas podem agravar esta carência ao reduzir os níveis de selénio nos...
