Valorization of natural resources - development of a functional plant-based bev...
Fernandes, Filipa Alexandra; Roriz, Custódio Lobo; Calhelha, Ricardo C.; Rodrigues, Paula; Pires, Tânia C.S.P.; Prieto Lage, Miguel A.Plant-based beverages are gaining attention due to their potential to offer sustainable and health-promoting alternatives to traditional dairy products. This study aimed to develop a dehydrated functional plant-based beverage composed of tigernut tubers (Cyperus esculentus L.), mukua pulp (Adansonia digitata L.), and thermal water. All matrices and the final beverage were fully characterized in terms of physica...
Nutraceuticals and dietary supplements: balancing out the pros and cons
Fernandes, Filipa Alexandra; Carocho, Márcio; Prieto Lage, Miguel A.; Barros, Lillian; Ferreira, Isabel C.F.R.; Heleno, Sandrina A.While the market is full of different dietary supplements, in most countries, legislation is clear and strict towards these products, with severe limitations on their health claims. Overall, the claims cannot go beyond the consumption of a said supplement will contribute to a healthy diet. Thus, the supplement industry has been reacting and changing their approach to consumers. One change is the considerable gr...
Cistus, Acacia, and Lemon verbena Valorization through Response Surface Methodo...
Fernandes, Filipa Alexandra; Carocho, Márcio; Finimundy, Tiane C.; Prieto Lage, Miguel A.; Ferreira, Isabel C.F.R.; Barros, Lillian; Heleno, Sandrina A.Cistus ladanifer L., Acacia dealbata L., and Aloysia citrodora Paláu were subject to an optimization procedure for two extraction techniques (heat-assisted extraction (HAE) and ultrasound-assisted extraction (UAE)). The extracts were then analyzed by HPLC-DAD-ESI/MS for their phenolic profile (cistus—15 compounds, acacia—21 compounds, and lemon verbena—9 compounds). The response surface methodology was applied,...
Effects of a Cyperus esculentus L. plant-based beverage on FVB/n female mice
Fernandes, Filipa Alexandra; Oliveira, Paula A.; Pinto, M.L.; Venâncio, Carlos; Félix, Luís; Medeiros-Fonseca, Beatriz; Correia, RossanaThis work evaluated the effects of the consumption of a plant-based beverage (Cyperus esculentus L., Adansonia digitata L., and thermal water) on the physiological parameters of mice over a 28-day period. Thirty-two female FVB/n mice (n = 8) were randomly assigned to one of four groups divided into two experimental protocols: Group 1 drank water and Group 2 drank a plant-based beverage for 24 h; in the second e...
Development and characterisation of gluten‐free fresh pasta using teff, rice, a...
Silveira, Tayse F. F. da; Hasni, Jihene; Portelada, Nathalie; Fernandes, Filipa Alexandra; Rodrigues, Paula; Lemos, André; Ferreira, Isabel C.F.R.To meet the demand for gluten-free (GF) products, this study developed artisanal fresh pasta using teff, rice, and buckwheat flours, enhanced with mineral-rich thermal waters (TW). A mixture design approach optimised flour proportions to balance texture, cooking time, water absorption, and cooking loss, along with functional properties such as total phenolic compounds (TPC) and antioxidant activity. Two promisi...
The generally recognized as safe (GRAS) microalgae Haematococcus pluvialis (wet...
Castillo, Aly; Finimundy, Tiane C.; Heleno, Sandrina A.; Rodrigues, Paula; Fernandes, Filipa Alexandra; Pereira, Simón; Lores, Marta; Barros, LillianThis work proposes the application of astaxanthin-rich H. pluvialis wet paste (HPW) as a partial substitute for wheat flour in the preparation of filloas, a dish that combines the basic ingredients of industrial bakery. The nutritional and color profile of HPW-enriched samples was evaluated by comparative analysis with a mixture of synthetic food dyes. The highest content of carotenoids (798 ± 12 µg g−1) and fatty...
Non-alkaloid nitrogen containing compounds
Pereira, Eliana; Fernandes, Filipa Alexandra; Mandim, Filipa; Ayuso, Manuel; Ferreira, Isabel C.F.R.; Caleja, Cristina; Barros, LillianPlants have been the target of a growing interest by the scientific community in chemical and nutritional characterization studies, due to the presence of bioactive compounds and their potential industrial use, namely in food and pharmaceutical sectors. Different secondary metabolites found in plants ensure their survival and reproduction. Non-alkaloids compounds are an important group of secondary metabolites ...
Arbutus unedo leaf extracts as potential dairy preservatives: case study on qua...
Derbassi, Nabila Ben; Pedrosa, Mariana C.; Heleno, Sandrina A.; Fernandes, Filipa Alexandra; Dias, Maria Inês; Calhelha, Ricardo C.; Rodrigues, PaulaThe plant kingdom is an endless source of molecules that can be applied in almost all realms of society. The food industry has profited from the use of plants and their derived materials for many decades. Recently, the food industry has been looking into plants to find different ways of either preserving, coloring or sweetening foods. In this work, leaf extracts of Arbutus unedo L. obtained by dynamic maceratio...

Fernandes, Filipa Alexandra; Heleno, Sandrina A.; Carocho, Márcio; Calhelha, Ricardo C.; Pires, Tânia C.S.; Freitas, Carlos AlbertoThe use of plants for medicinal purposes goes back to ancient times. Adansonia digitata L. is a tree native to the African continent with many traditional uses, including medicinal and food. The fruit of this tree is commonly known as mukua, and consists of pulp, fibrous tissue, and seeds. The pulp has been approved as a food ingredient by the European Commission and the Food and Drug Administration. Consumers ...
Valorização de biorresíduos da produção de sumo de laranja: extração de ácido c...
Fernandes, Filipa Alexandra; Pinela, José; Carocho, Márcio; Prieto Lage, Miguel A.; Heleno, Sandrina A.; Barros, LillianA laranja é um dos frutos mais consumidos mundialmente, sendo uma parcela considerável destinada à produção de sumos, operação industrial que gera uma grande quantidade de resíduos (polpa, cascas e sementes). Uma parte destes biorresíduos é utilizada na produção de ração animal; contudo, uma quantidade significativa ainda é depositada em aterros sanitários, gerando um impacto ambiental considerável [1,2,3].
