Acrilamida em cereais e derivados: validação do método analítico e resultados p...
Copeto, Sandra; Jesus, Susana; Delgado, Inês; Coelho, InêsA reação de Maillard, responsável pela cor, sabor e aroma dos alimentos, também produz substâncias nocivas, como a acrilamida (AA). Esta amida insaturada forma-se quando alimentos ricos em hidratos de carbono, como pão, batatas e café, são cozinhados a temperaturas elevadas e humidade baixa. A União Europeia classificou a AA como carcinogénica (Categoria 1B), mutagénica (Categoria 1B) e tóxica para a reprodução...
Chemometric and multielement techniques for the exploratory analysis of honey q...
Rios, Francisco Teodoro; Lobo, Manuel Oscar; Castanheira, Isabel; Delgado, Inês; Nascimiento , Ana; Sammán, NormaThe proximal and mineral profiles of multi floral honeys from different geographic regions were determined and related to their origin. Moisture, °Brix sugars, ash, pH, free acidity, water activity (aw) and minerals content were determined by AOAC methods. In the exploratory analysis, non-supervised chemometric methods were applied to build classification rules and relate the origin of the samples based on thei...
Valorisation of sea urchin (Paracentrotus lividus) gonads through canning
Camacho, Carolina; Oliveira, Helena; Serrano, Carmo; Delgado, Inês; Coelho, Inês; Pedro, Sónia; Lourenço, Helena; Bandarra, Narcisa M.; Marques, AntónioFresh sea urchin (Paracentrotus lividus) gonads are a delicacy with short seasonal availability, very often heterogeneous in size and intrinsic characteristics. This study aimed to valorise this resource through the preparation of canned products (with/without Porphyra spp.) and evaluate their physicochemical and sensory quality (3–12 months). Canning contributed to a decrease in protein, K and most carotenoids...
Study around the Barroso mine (Portugal): Baseline levels of lithium for assess...
Jesus, Susana; Ventura, Marta; Assunção, Ricardo; Gueifão, Sandra; Delgado, Inês; Rego, Andreia; Ribeiro, Mariana; Martins, Marta; Neves, OrquídiaThe energetic green transition is increasing the demand for lithium (Li) exploitation. However, the Li supply faces challenges like limited reserves and environmental concerns. This pioneer study aims to characterize the Li concentrations in the region around the Barroso mine, in Portugal, by collecting and analyzing samples of cabbage, potato, drinking and irrigation water and soil from two nearby sites, and p...
Mackerel and Seaweed Burger as a Functional Product for Brain and Cognitive Agi...
Cardoso, Carlos; Valentim, Jorge; Gomes, Romina; Matos, Joana; Rego, Andreia; Coelho, Inês; Delgado, Inês; Motta, Carla; Castanheira, IsabelMost world countries are experiencing a remarkable aging process. Meanwhile, 50 million people are affected by Alzheimer’s disease (AD) and related dementia and there is an increasing trend in the incidence of these major health problems. In order to address these, the increasing evidence suggesting the protective effect of dietary interventions against cognitive decline during aging may suggest a response to t...
Balancing act: tubulin glutamylation and microtubule dynamics in Toxoplasma gondii
Delgado, Inês; Gonçalves, João; Fernandes, Rita; Zúquete, Sara; Basto, Afonso P.; Leitão, Alexandre; Soares, Helena; Nolasco, SofiaThe success of the intracellular parasite Toxoplasma gondii in invading host cells relies on the apical complex, a specialized microtubule cytoskeleton structure associated with secretory organelles. The T. gondii genome encodes three isoforms of both α- and β-tubulin, which undergo specific post-translational modifications (PTMs), altering the biochemical and biophysical proprieties of microtubules and modulat...
Inorganic contaminants and micronutrients in foods consumed by the vegetarian P...
Gueifão, Sandra; Rego, Andreia; Delgado, Inês; Ventura, Marta; Coelho, InêsAim: The present study aimed to determine the profile of micronutrients and inorganic contaminants in the plant-based and dairy food products most consumed by the Portuguese population. Methods: The sampling plan followed the Total Diet Studies (TDS) methodology and included representative samples of the Portuguese vegetarian diet, chosen based on the National Food and Physical Activity Survey. Five main food g...

Namorado, Sónia; Ogura, Joana; Silva, Susana; Coelho, Inês; Delgado, Inês; Gueifão, Sandra; Ventura, Marta; Martins, Carla; Viegas, SusanaIntrodução: Tem sido amplamente reconhecido que a exposição humana a determinados químicos tem um impacto negativo na saúde humana. Importa, pois, caracterizar e monitorização a exposição da população por forma a, se necessário, suportar o desenvolvimento de medidas que levem à redução dessa exposição. Objetivo: Caracterizar a exposição da população adulta portuguesa a um conjunto de substâncias químicas consid...
Iodine profile in foods consumed in vegetarian diets
Delgado, Inês; Ventura, Marta; Gueifão, Sandra; Rego, Andreia; Castanheira, Isabel; Coelho, InêsVegetarian diets have gained popularity in the last decade, and it has been found that increased consumption of plant-based foods has numerous health benefits [1]. The number of vegetarians has quadrupled in the last ten years, currently representing around 9% of the population residing in Portugal [2,3]. Therefore, the nutritional study of the foods most consumed by the vegetarian population becomes important....
