Rapid screening of fumonisins in maize using near-infrared spectroscopy (NIRS) ...
Sampaio, Pedro; Barros, Sílvia Cruz; Freitas, Andreia; Silva, Ana Sanches; Brites, Carla; Carbas, BrunaFumonisins occurrence in maize represents a significant global challenge, impacting economic stability and food safety. This study evaluates the potential of near-infrared (NIR) spectroscopy combined with chemometric al- gorithms to detect fumonisins in maize. For fumonisin B1 (FB1) and B2 (FB2) levels were developed predictive NIR models using partial least squares (PLS) and artificial neural networks (ANN). P...
Impact of photoselective nets on phenolic composition and antioxidant capacity ...
Teixeira, João David; Sousa, Miguel Leão de; Barros, Sílvia Cruz; Parpot, Pier; Almeida, Carina Manuela Fernandes; Silva, Ana SanchesPhenolic compounds in apples provide significant health benefits, including antioxidant, and anti-inflammatory properties. The phenolic profile and content in apples are influenced by genetics, environmental factors, and agricultural practices. Photoselective nets, which are designed to filter specific wavelengths of light, might impact fruit quality and phenolic content. This study aimed to assess the effects ...
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...
