Thermally processed eggshells as a renewable source of calcium carbonate for in...
Silva, Sara; Marçal, Sara; Ribeiro, Tânia; Pintado, ManuelaCalcium carbonate (CaCO?) is a vital industrial material used extensively in pharmaceuticals, food production, construction, and environmental remediation. Current CaCO? sourcing methods, primarily reliant on mining limestone and chalk, present significant environmental challenges, including habitat destruction, high energy consumption, and carbon emissions. To address these concerns, this study explores the po...
Circular economy synergies: leveraging agrifood waste for sustainable shoe mate...
Silva, Sara; Ribeiro, Tânia; Silva, Isa; Marçal, Sara; Pintado, ManuelaThe shoe industry needs more sustainable practices to reduce its environmental impact not only in terms of processes and generated waste but also in its dependence on virgin raw materials. To address the last, there is an unconventional synergy that can prove to be disruptive. A synergy with the agrifood sector. While cascading use and food first principles mean that priority should be given to food and feed ap...
Metabolomic profile of vaccinium corymbosum leaves: exploiting diversity among ...
Ribeiro, Tânia; Pintado, Manuela E.; Sousa, ClaraBlueberry (Vaccinium corymbosum) leaves are often discarded as agricultural by-products despite their potential abundance in bioactive compounds. However, comprehensive knowledge of their phytochemical profile remains limited, especially at the cultivar level. To address this gap, this study performed untargeted metabolomic profiling of blueberry leaves from ten cultivars using UHPLC-QTOF MS. Metabolites were a...
Phenolic Profile and Antioxidant and Biological Activities of Plant Extracts Ri...
Melo, Adma N.F.; Afonso, Tiago B.; Pedrosa, Mariana C.; Carvalho, Marta; Rodrigues, Cláudia; Dias, Maria Inês; Ribeiro, Tânia; Machado, ManuelaIn this work, hydroethanolic plant extracts (acorn husk, laurel, eucalyptus, and rockrose leaves) were screened for their content in condensed tannins (HPLC-DAD/MS), polyphenol content, antioxidant, antimicrobial, and antiviral activities, and lack of toxicity. The results showed the highest values of condensed tannins found for laurel and eucalyptus extracts, while the total phenolic content ranged within 204....
Omega-3 fatty acids from fish by-products: Innovative extraction and applicatio...
Rodrigues, Matilde; Rosa, Ana; Almeida, André; Martins, Rui; Ribeiro, Tânia; Pintado, Manuela; Gonçalves, Raquel F.S.; Pinheiro, Ana C.Omega -3 fatty acids (O3FA) are essential nutrients that play a crucial role in maintaining human and animal health. They are known for their numerous health claims, including cardiovascular benefits, contributing to both the prevention and treatment of immunological, neurological, reproductive, and cardiovascular complications, and supporting overall well-being. Fish, especially oily fish, comprise rich source...
A paradigm shift in skincare through the power of grape seed-loaded liposomes
Castro, Maria Leonor de; Azevedo-Silva, João; Valente, Diana; Machado, Adriana; Ribeiro, Tânia; Ferreira, João Paulo; Pintado, Manuela; Ramos, OscarThe skin undergoes natural aging and is prone to various conditions/pathologies due to constant exposure to environmental stressors and abrasions. The cosmetic industry has revolutionized skincare, each time in a higher trend for natural and organic products. The growing trend of clean beauty, driven by consumer demand for non-toxic and environmentally friendly products, is increasingly intertwined with sustain...
Elevating skincare science: grape seed extract encapsulation for dermatological...
Castro, Maria Leonor; Azevedo-Silva, João; Valente, Diana; Machado, Adriana; Ribeiro, Tânia; Ferreira, João Paulo; Pintado, Manuela; Ramos, Oscar L.The skin is the largest organ in the human body and serves multiple functions such as barrier protection and thermoregulation. The maintenance of its integrity and healthy structure is of paramount importance. Accordingly, technological advances in cosmetic sciences have been directed towards optimizing these factors. Plant-derived ingredients have been explored for their bioactivity profiles and sustainable so...
Fucoidans: exploring its neuroprotective mechanisms and therapeutic application...
Batista, Patrícia; Cunha, Sara A.; Ribeiro, Tânia; Borges, Sandra; Baptista-Silva, Sara; Oliveira-Silva, Patrícia; Pintado, ManuelaBackground: Marine-derived natural products have been attracting attention from both the food and pharmaceutical sectors due to their promising therapeutic attributes. Algae and their biomolecules are examples of marine-derived products for ongoing research endeavors. Fucoidan, an algae-derived polysaccharide, has emerged as a recent biomolecule related to a diverse array of beneficial properties, with particul...
