Exploring the development of a clean-label vegan burger enriched with fermented...
Bassani, Joseane C.; Martins, Valter F. R.; Barbosa, Joana; Coelho, Marta; Sousa, Clara; Steffens, Juliana; Backes, Geciane T.; Pereira, HugoHaematococcus pluvialis and Porphyridium cruentum are red microalgae with high biotechnological potential due to their rich composition of bioactive compounds. However, their intense flavor limits their application in food products. This study evaluated the impact of fermentation with Lactiplantibacillus plantarum (30 ?C for 48 h; LAB-to-biomass ratio of 0.1:1; 106 CFU/mL) on the physicochemical and functional ...
Effects of glyoxylic acid on metabolism and ripening of ‘Rocha’ pears treated w...
Dias, Cindy; Sousa, Clara; Vasconcelos, Marta W.; Ferrante, António; Pintado, ManuelaThe application of 1-methylcyclopropene (1-MCP) is widely used to extend the storage life of climacteric fruits, such as ‘Rocha’ pears. However, the suppression of ethylene’s action by 1-MCP often results in excessive ripening delay, compromising fruit quality and consumer acceptance. In this study, we investigated the potential of glyoxylic acid (GLA) to counteract the effects of 1-MCP and promote ripening. To...
Machine learning-based spectral analyses for camellia japonica cultivar identif...
Rodrigues, Pedro Miguel; Sousa, ClaraCamellia japonica is a plant species with high cultural and biological relevance. Besides being used as an ornamental plant species, C. japonica has relevant biological properties. Due to hybridization, thousands of cultivars are known, and their accurate identification is mandatory. Infrared spectroscopy is currently recognized as an accurate and rapid technique for species and/or subspecies identifications, i...
Metabolomic profile of vaccinium corymbosum leaves: exploiting diversity among ...
Ribeiro, Tânia; Pintado, Manuela E.; Sousa, ClaraBlueberry (Vaccinium corymbosum) leaves are often discarded as agricultural by-products despite their potential abundance in bioactive compounds. However, comprehensive knowledge of their phytochemical profile remains limited, especially at the cultivar level. To address this gap, this study performed untargeted metabolomic profiling of blueberry leaves from ten cultivars using UHPLC-QTOF MS. Metabolites were a...
Near-infrared spectroscopy machine-learning spectral analysis tool for blueberr...
Ribeiro, Pedro; Barbosa, Maria Inês; Sousa, Clara; Rodrigues, Pedro MiguelVaccinium corymbosum is one of the main sources of commercialized blueberries across the world. This species has a large number of distinct cultivars, leading to significantly different berries characteristics such as size, sweetness, production rate, and growing season. In this context, accurate cultivar discrimination is of significant relevance, and currently, it is mostly performed through berries examinati...

Decellularized small intestine for burn wound treatment: a tissue engineering p...
Silva, Inês V.; Rosadas, Marta; Rodrigues, Ilda; Sousa, Clara; Ribeiro, Viviana; Costa, Raquel; Moroni, Lorenzo; Oliveira, Ana L.Introduction: Burn injuries are a significant global health issue, causing approximately 11 million injuries and 180,000 fatalities each year (1). Beyond physical trauma, burn injuries lead to complications such as infections and sepsis. Burn scars can also diminish quality of life by affecting joint mobility and daily activities (2,3). Conventional dressings and autografts have limitations, necessitating novel...
Predicting iron deficiency and oxidative stress in glycine max through Fourier ...
Santos, Carla S.; Sousa, Clara; Bagheri, Maryam; Pinho, Simão; Vasconcelos, MartaAims: The excessive use of fertilizers is a problem in current agricultural systems, and sustainable farming practices, including precision agriculture, demand the use of new technologies to manage plant stress at an early stage. To sustainably manage iron (Fe) fertilization in agricultural fields, it is urgent to develop early detection methods for Fe deficiency, and linked oxidative stress, in plant leaves. H...
Safety profile of ZnO active packaging PBAT based biomaterial for food packagin...
Singh, Srishti; Pereira, Joel; Guerreiro, Patricia; Selbourne, Céu; Paula, Cidália; Cunha, António; Sousa, Clara; Poças, FátimaMaterials produced with polybutylene adipate terephthalate (PBAT) and starch are raising great interest for packaging and food contact applications, including as support for active antimicrobial agents such as zinc oxide nanoparticles (ZnO). Studies focusing on the safety of these materials as evaluated with the current reference rules for food contact materials, are lacking. A commercially available PBAT/starc...
Discrimination and quantification of cotton and polyester textile samples using...
Paz, Maria Luís; Sousa, ClaraIn the textile industry, cotton and polyester (PES) are among the most used fibres to produce clothes. The correct identification and accurate composition estimate of fibres are mandatory, and environmentally friendly and precise techniques are welcome. In this context, the use of near-infrared (NIR) and mid-infrared (MIR) spectroscopies to distinguish between cotton and PES samples and further estimate the cot...
