Unlocking the potential of Citrus medica L.: antioxidant capacity and phenolic ...
Mateus, Ana Rita Soares; Teixeira, João David; Barros, Silvia Cruz; Almeida, Carina Manuela Fernandes; Silva, Sónia Carina; Sanches-Silva, AnaCitrus medica L. is a traditional citrus fruit that is rich in bioactive compounds and has the potential to be used as a natural source of food additives. This study aims to evaluate the antioxidant capacity and characterize the phenolic compounds present in the peels (including flavedo and albedo), pulp, and seeds of citron. The results showed that, compared to the other parts, the pulp had a substantially hig...
The Bright and Dark Sides of Herbal Infusions: Assessment of Antioxidant Capaci...
Mateus, Ana Rita Soares; Crisafulli, Carmen; Vilhena, Matilde; Barros, Sílvia; Pena, Angelina; Silva, Ana SanchesHerbal infusions are highly popular beverages consumed daily due to their health benefits and antioxidant properties. However, the presence of plant toxins, such as tropane alkaloids, constitutes a recent health concern for herbal infusions. This work presents an optimized and validated methodology based on the QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) extraction procedure followed by Ultra-Hig...
Antioxidant Capacity and Phenolics Profile of Portuguese Traditional Cultivars ...
Teixeira, João David; Mateus, Ana Rita Soares; Sanchez, Claudia; Parpot, Pier; Almeida, Carina; Silva, Ana SanchesPears (Pyrus communis L.) and apples (Malus domestica Borkh.) are two of the most popular fruits worldwide. The phenolic compounds they offer are associated with human health benefits due to their antioxidant properties. Since these fruits' by-products are not yet fully exploited, it is important to characterize them, especially in terms of their antioxidant properties. The aim of this study was to determine th...
Ergot Alkaloids on Cereals and Seeds: Analytical Methods, Occurrence, and Futur...
Silva, Ângela; Mateus, Ana Rita Soares; Barros, Sílvia Cruz; Silva, Ana SanchesErgot alkaloids are secondary metabolites resulting from fungi of the genus Claviceps that have proven to be highly toxic. These mycotoxins commonly infect cereal crops such as wheat, rye, barley, and oats. Due to the increase worldwide consumption of cereal and cereal-based products, the presence of ergot alkaloids in food presents a concern for human safety. For this reason, it is essential to develop several...
Comparison of the phenolics profile of regional and commercial cultivars of app...
Teixeira, João David; Mateus, Ana Rita Soares; Parpot, Pier; Sousa, Miguel Leão de; Sánchez, Cláudia; Almeida, Carina; Sanches-Silva, AnaPhenolic compounds are believed to have antioxidant properties, and therefore many studies have been conducted in order to search for the presence of such compounds in food matrices and the effects that they cause [1, 2]. Some of the most common sources of phenolic compounds in human diet are fruit and fruit based products, particularly apples [3]. An Ultra-High Performance Liquid Chromatography combined with T...

By-products of dates, cherries, plums and artichokes: A source of valuable bioa...
Mateus, Ana Rita Soares; Pena, Angelina; Sendón, Raquel; Almeida, Carina; Nieto, Gonçalo Almeida; Khwaldia, Khaoula; Silva, Ana SanchesBackground Food processing is fundamental to extend the shelf-life of food products. During the processing, several parts of food are wasted. FAO indicated that about one-third of the world's food production for human consumption was lost or wasted, and food waste is an environmental, economic, and social problem. Fruits and vegetables are the food groups with the highest amount of food waste, both in food proc...
Evaluation of the individual phenolic compounds of regional cultivars of pears ...
Teixeira, João David; Mateus, Ana Rita Soares; Sánchez, Claudia; Parpot, Pier; Almeida, Carina; Sanches-Silva, AnaPear (Pyrus communis L.) is a fruit of great interest because their consumption offers nutritional as well as medicinal advantages [1]. The most well-known and studied properties associated with pears are antioxidant and anti-inflammatory properties [2] these are associated with the presence of phenolic compounds, mainly in the peels but also, in smaller amounts, in its mesocarp (pulp) [3]. In this work, an Ult...
