- Crispy orange: a multi-purpose ready-to-eat snackPublication . Cristóvão, Mário André Monteiro; Camelo, Alexandra; Martins, Ana; Silveira, Ana; Riscado, Ana; Rodrigues, Ana; Baptista, Cátia; Beato, Helena; Vasconcelos, Vanessa; Paulo, Luísa; Pitacas, F.I.; Rodrigues, A.M.; Espírito Santo, Christophe; Brandão, InêsWith the war in Ukraine reshaping world trade, there is now a surplus of orange production in Europe, affecting the price in Portugal. Algarve is no exception, where producers are offering the fruit for lack of buyers. An innovative solution is on the agenda: transforming this Mediterranean diet fruit into a crispy ready-to-eat snack. The crispy orange snack is made exclusively from dehydrated oranges (and no other ingredients) and is not yet available in the market. Not only can this product be made from surplus orange production, but it can also be used in a variety of ways, including as a crunchy, ready-to-eat snack, as an edible cake topper, or even as an ingredient in beverages such as sparkling and tonic water, or gin. Following development, the product was fully characterized regarding nutritional value, water activity (aw), microbiology and sensory analysis with 66 consumers. Interestingly, unlike other orange products such as 100% orange juice, the crispy orange snack has a high fibre content (10% of the recommended daily dose). This is a major point as fibre is essential for regulating blood sugar levels. Furthermore, 95.5% of consumers who tested the product would buy it if it were available.
- Development and characterization of an orange dehydrated crispy snackPublication . Cristóvão, Mário André Monteiro; Camelo, Alexandra; Martins, Ana; Silveira, Ana; Riscado, Ana; Rodrigues, Ana; Batista, Cátia; Beato, Helena; Vasconcelos, Vanessa; Paulo, Luísa; Pitacas, F.I.; Rodrigues, A.M.; Espírito Santo, Christophe; Brandão, InêsOranges are mainly consumed as fresh fruit, processed orange (mostly as juice) are global commodity. As a natural ingredient. As an edible topping. Ready-to-eat snack. Presence of vectors in chestnuts. Dried fruits are used as versatile foods, as snacks or as an ingredient to enrich other foods. One of the most appreciated proprieties of a snack is presenting a crunchy texture. This study aims to create a new product by dehydration of sweet oranges in an innovative format.
- Enhancing the nutritional value of a sugar-free Greek-style yoghurt by incorporating strawberry-tree (Arbutus unedo L.) fruit and peach (Prunus persica)Publication . Carriço, Raquel; Marcos, Joana; Baptista, Cátia; Vasconcelos, Vanessa; Beato, Helena; Riscado, Ana; Silveira, Ana; Pitacas, F.I.; Paulo, Luísa; Rodrigues, A.M.; Palma, Maria Lídia; Nicolai, Marisa; Menezes, Regina; Pereira, Paula; Espírito Santo, Christophe; Cristóvão, Mário; Brandão, InêsAs consumers become more health-conscious, they are increasingly seeking out foods that offer potential health benefits, such as yoghurts. To encourage more sustainable and healthy consumption habits, it is important to develop food products using local food ingredients. This study focused on fermented dairy products, namely by developing various formulations of Greek yoghurt using strawberry-tree fruit (Arbutus unedo L.) (STF) and peach (Prunus persica) puree, with no added sugar. Both peach and STF were sourced locally. A sensory analysis was performed to determine the preferred formulation, selecting either z1 (20% STF and 80% peach) or z2 (30% STF and 70% peach). After comparing the two, z1 emerged as the preferred formulation. For this formulation, physicochemical and microbiological analyses were conducted. A Greek yoghurt that incorporates peach and STF was developed while satisfying the requirements for “low-fat”, “low-saturated fat”, and “no added sugars” nutrition claims. These are all important features that align with the guidelines provided by the World Health Organization in promoting a healthy diet that encourages reduced fat and saturated fat intake, limited consumption of added sugars, and increased fibre content. To the best of our knowledge, this is the first time describing a Greek yoghurt containing STF purée.
- Fatty acid profile, total fat, protein, moisture and ash in different edible parts of Albacore Tuna (Thunnus alalunga Bonnaterre, 1788) - Preliminary resultsPublication . Pitacas, F.I.; Benito Bernáldez, María José; Blasco Ruíz, Manuel; Lopéz González, José Antonio; Palencia, Rocío; Anjos, O.; Vasconcelos, Vanessa; Paulo, Luísa; Rodrigues, A.M.This study assessed the specific proximal composition and fatty acid profile of different edible parts of a 13 kg male Thunnus alalunga (Bonnaterre, 1788) caught in June 2023 in the Cantabrian Sea.
- Novel product using a native breed of sheep (Merino da Beira Baixa): smoked lambPublication . Cristóvão, Mário André Monteiro; Rodrigues, Ana; Silveira, Ana; Baptista, Cátia; Beato, Helena; Vasconcelos, Vanessa; Paulo, Luísa; Pitacas, F.I.; Rodrigues, A.M.; Espírito Santo, Christophe; Brandão, InêsMerino breed emerged, in the textile industry renowned for their high-quality wool. This work aims to develop a novel food product. In Castelo Branco the “Merino da Beira Baixa” is part of 3 PDO cheeses and a PGI meat “Amarelo”, “Picante” e “Castelo Branco” and “Borrego da Beira”.The breed has experienced a decline in influence due to plummeting wool prices and an inability to compete with more productive breeds. This work aims to develop a novel food product using a ancestral breed and technique (smoking).

- Nutritional characteristics and minerals of Lardosa cowpea landraces: a strategic legume species for the futurePublication . Beato, Helena; Resende, Mafalda; Paulo, Luísa; Martins, Catarina; Cristóvão, Mário André Monteiro; Vasconcelos, Vanessa; Brandão, Inês; Pitacas, F.I.; Rodrigues, A.M.; Espírito Santo, ChristopheCowpeas have been cultivated at least since the 8th century BC. [1; 2]. This grain legume (Vigna unguiculata L. Walp.), one of Africa's natural food gifts to the world, is characterized by its high nutritional value, ability to fix nitrogen and great tolerance to drought. The tolerance of this legume to low fertility soils, high temperatures and scarce water regimes makes this one of the most resistant crops to adverse edaphoclimatic conditions. It is certainly a very important culture in southern European countries like Portugal.
