Añibarro-Ortega, Mikel; Dias, Maria Inês; Petrović, Jovana; Núñez, Sonia; Calhelha, Ricardo C.; Costa, Eduardo M.; Machado, M.; Pintado, ManuelaThis study explored the valorization of post-harvest eggplant aerial parts as a sustainable source of value-added ingredients by investigating their phenolic composition and in vitro bioactive properties. HPLC-DAD-ESI/MSn analysis identified chlorogenic acid derivatives as the predominant phenolic compounds (53 % of the phenolic fraction), followed by O-glycosylated kaempferol and quercetin. The extract display...

Martins, V.; Machado, M.; Costa, E.; Gomes, A. M.; Poças, F.; Pintado, M.; Morais, R. M. S. C.; Morais, A. M. M. B.Introduction: Macroalgae are a good source of nutrients, such as carbohydrates (dietary fiber and polysaccharides), proteins, lipids and minerals [1,2]. Fucus sp. is composed of valuable bioactive compounds, such as fucoxanthin, vitamins, water-soluble (vitamin C and of complex B) and fat-soluble (vitamins A, D, E and K), phenolic compounds, lipids (MUFA and PUFA), and polysaccharides (fucoidans and alginic aci...
Inflammatory potential of high-protein hybrid yogurt
Gigante, M. L.; Baptista, D. P.; Silva, K. K. P.; Machado, M.; Costa, E.; Pintado, M.Introduction: Partly replacing dairy proteins with plant proteins in processed foods is a potential alternative strategy for creating a more sustainable food system. Furthermore, with the growth of the elderly population worldwide, there is an interest in developing foods to promote the health of the elderly.

Martins, V.; Coelho, M.; Machado, M.; Costa, E.; Gomes, A. M.; Poças, F.; Pintado, M.; Morais, R. M. S. C.; Morais, A. M. M. B.Introduction: Macroalgae are a good source of nutrients, such as carbohydrates (dietary fiber and polysaccharides), proteins, lipids and minerals, and they are sustainable, because they do not compete with food crops for arable land and potable water [1,2]. Fucus sp. is composed of valuable bioactive compounds, such as fucoxanthin, vitamins, water-soluble vitamins (vitamin C and of complex B) and fat-soluble vi...
Desenvolvimento de nanofertilizantes pela técnica de camada-sobre-camada
Saraiva, Raquel; Ferreira, Q.; Rodrigues, G.; Machado, M.; Oliveira, A.; Oliveira, MargaridaO desenvolvimento de nanofertilizantes é uma alternativa que se afigura de grande interesse no contexto económico e climático atual. Por um lado, é necessário reduzir a extração e o uso de matérias-primas utilizadas na produção de alimentos e por outro lado, a libertação desses compostos no solo deve ser realizada de forma criteriosa e eficiente, nos momentos em que as culturas necessitam. O objetivo deste trab...

Reis, B.; Ramos-Pinto, L.; Martos-Sitcha, J. A.; Machado, M.; Azeredo, R.; Fernandez-Boo, S.; Engrola, S.; Unamunzaga, C.; Calduch-Giner, J.To enhance fish general health, feeds can be supplemented with health-promoting additives, reducing the need to use chemotherapeutics. Incorporation of marine algae biomasses in aquafeeds has been shown to improve fish immune status by enhancing innate immune response. This study evaluated the effects of Phaeodactylum tricornutum incorporation in feed by two different processes, either as freeze-dried biomass o...
