Sustainability assessment of collagen extraction from fish skins: A comparative...
Miguel P. Batista; Fernández, Naiara; Gaspar, Frédéric B.; Bronze, MR; Duarte, Ana Rita C.; Ortigueira, Joana; Lopes, TiagoABSTRACT: Collagen from blue shark skins offers a promising solution to utilize fishery by-products, reducing waste and improving resource efficiency. This study develops green chemistry-based extraction processes to minimize reliance on traditional chemical methods and lower environmental impacts, prioritizing sustainability and circularity. Two methods for collagen extraction are compared: a conventional alka...
Enzymatic hydrolysis allows an integral valorization of nannochloropsis oceanic...
Cunha, Sara A.; Coscueta, Ezequiel R.; Alexandre, Agostinho M. R. C.; Partidário, Ana Maria Carvalho; Fernández, Naiara; Paiva, AlexandreNannochloropsis oceanica is a microalga with relevant protein content, making it a potential source of bioactive peptides. Furthermore, it is also rich in fatty acids, with a special focus on eicosapentaenoic acid, an omega-3 fatty acid mainly obtained from marine animal sources, with high importance for human health. N. oceanica has a rigid cell wall constraining protein extraction, thus hydrolyzing it may hel...
Biodegradable film production from agroforestry and fishery residues with activ...
Gaspar, Marisa C.; Leocádio, João; Mendes, Cátia V. T.; Cardeira, Martim; Fernández, Naiara; Matias, Ana; Carvalho, Maria G. V. S.; Braga, Mara E. M.This paper is dedicated to the memory of A. T. Portugal, the University of Coimbra leader of Multibiorefinery project, for his partnership and commitment; An increasing interest in food packaging materials without environmental impact and able to improve shelf life has emerged in the last decade. The aim of this work was to produce biodegradable films from agroforestry (pine stumps) and fishery (chitosan) resid...
Multi-step subcritical water extracts of fucus vesiculosus l. And codium toment...
Soares, Cristina; Paíga, Paula; Marques, Marta; Neto, Tânia; Carvalho, Ana Paula; Paiva, Alexandre; Simões, Pedro; Costa, Leonor; Bernardo, AnaMental health and active aging are two of the main concerns in the 21st century. To search for new neuroprotective compounds, extracts of Codium tomentosum Stackhouse and Fucus vesiculosus L. were obtained through multi-step (four step) subcritical water extraction using a temperature gradient. The safety assessment of the extracts was performed by screening pharmaceutical compounds and pesticides by UHPLC-MS/M...

Combined hydrothermal pre-treatment and enzymatic hydrolysis of corn fibre: pro...
Valério, Rita; Serra, Ana Teresa; Baixinho, João; Cardeira, Martim; Fernández, Naiara; Bronze, MR; Duarte, Luís C.; Tavares, Maria L.; Crespo, JoãoABSTRACT: Ferulic acid may be used as a nutraceutical ingredient or as a substrate to produce bio-vanillin. There is an increasing market demand for ferulic acid obtained from natural sources such as low-cost agro-industrial by-products, due to its potential applications as nutraceutical ingredient and as a substrate to produce biovanillin. This work aims to study ferulic acid recovery from corn fibre (one of t...
