Application of microalgae as natural colorant for pastry and confectionary prod...
Pereira, Tatiana; Barroso, Sonia; Pinto, Filipa R.; Silva, Frederica; Teixeira, Paula; Mendes, Susana; Gil, Maria M.Modern consumers demand the replacement of synthetic colorants with natural alternatives. Microalgae can serve as an alternative source for these colorants since they hold significant amounts of pigments. This study aimed to evaluate the potential of using microalgae biomass and extracts as natural colorants for pastry and confectionary products. The application of different biomass and levels of Chlorella vulg...
Consumer's perceptions and motivations on the consumption of fortified foods an...
Silva, Frederica; Pereira, Tatiana; Mendes, Susana; Gordo, Leonel; Gil, Maria ManuelConsumer attitudes and acceptance of emerging technologies in the food sector, as well as their application, are determining factors for their successful implementation. In this study, a survey was conducted in order to better know and understand the perception, motivation and consumption associated with fortified foods and 3DPF (3-Dimensional Printing Food). Key points such as food neophobia and factors involv...
Increasing biological knowledge for better management of by-catch species: Age,...
Sequeira, Vera; Sousa, Inês; Neves, Ana; Vieira, Ana Rita; Silva, Elisabete; Silva, Frederica; Duarte, Ana Marta; Mendes, Susana; Ganhão, RuiGurnards are a valuable by-catch of mixed demersal fisheries and are commercially important in European waters, but they are often discarded, reported under “mixed gurnards” and with incomplete biological information by species. In the present work, a total of 558 piper gurnard specimens of between 10.9 and 44.4 cm (1 to 11 years) and 425 red gurnard specimens of between 10.2 and 42.1 cm (0 to 9 years) from the...

Annual variations in the mineral element content of five fish species from the ...
Pinto, Filipa R.; Duarte, Ana M.; Silva, Frederica; Barroso, Sónia; Mendes, Susana; Pinto, Edgar; Almeida, Agostinho; Sequeira, Vera; Vieira, Ana RitaThe most consumed fish species in Portugal do not correspond to the most caught fish species on the Portuguese coast. From the point of view of ocean sustainability and economics, it is important to study unexploited or underexploited fish species that have the potential to be introduced into the food market. This potential can be reflected by their nutritional value, where mineral elements are often overlooked...
Seasonal study of the nutritional composition of unexploited and low commercial...
Duarte, Ana M.; Silva, Frederica; Mendes, Susana; Pinto, Filipa R.; Barroso, Sonia; Silva, Elisabete; Neves, Ana; Sequeira, VeraTarget species diversification is essential for fisheries sustainability and fish market revitalization. Fish discards are a widely recognized problem resulting from fisheries worldwide, and are of major concern for all sector players, from administrations, to fishermen, and scientists. However, non-target species are seldom studied, and information on nutritional profiles and seasonal changes in nutritional pr...

Reproduction of the Blue Jack Mackerel, Trachurus picturatus, in Western Portug...
Neves, Ana; Sequeira, Vera; Vieira, Ana Rita; Silva, Elisabete; Silva, Frederica; Duarte, Ana Marta; Mendes, Susana; Ganhão, Rui; Assis, CarlosBlue jack mackerel, Trachurus picturatus, is the fifth most landed fish species in mainland Portugal, but information on its reproductive biology is scarce. From September 2018 to August 2019, 626 specimens were collected from commercial vessels to clarify the reproductive strategy of the T. picturatus population off the west coast of Portugal. The proportion and length range of males and females were similar. ...
Modelling fish growth with imperfect data: The case of Trachurus picturatus
Neves, Ana; Vieira, Ana Rita; Sequeira, Vera; Silva, Elisabete; Silva, Frederica; Duarte, Ana Marta; Mendes, Susana; Ganhão, Rui; Assis, CarlosGrowth modelling is essential to inform fisheries management but is often hampered by sampling biases and imperfect data. Additional methods such as interpolating data through backcalculation may be used to account for sampling bias but are often complex and time-consuming. Here, we present an approach to improve plausibility in growth estimates when small individuals are under-sampled, based on Bayesian fittin...
