Kaolin foliar spray induces positive modifications in volatile compounds and fr...
Dinis, Lia Tânia; Pereira, Sandra; Fraga, Irene; Rocha, Sílvia M.; Costa, Carina; Martins, Cátia; Vilela, Alice; Arrobas, MargaridaSolar radiation and temperature play crucial roles in grapevine metabolic processes and are known to have a positive impact on grape berry composition; however, excessive exposure to these factors can be detrimental. Kaolin-based particle film technology has emerged as a valuable solution for mitigating the effects of heat and water stresses in vineyards. This work aimed to evaluate the effects of kaolin applic...
ß-Farnesene exogenous application as a novel damage induction model to fast exp...
Dias, Cindy; Amaro, Ana; Fonseca, Alexandre; Ferrante, António; Silvestre, Armando; Rocha, Sílvia M.; Isidoro, Nélson; Pintado, ManuelaSince the prohibition of diphenylamine, replacement strategies have been needed for long-term disorder prevention, namely superficial scald (SC), in fruit. However, as this disorder only appears after months under cold storage, the assessment of effective strategies to prevent this disorder requires long periods. To tackle this challenge, we report in this paper a rapid and reliable system to induce symptoms, s...
Chromatographic-Based Platforms as New Avenues for Scientific Progress and Sust...
Câmara, José S.; Martins, Cátia; Pereira, Jorge A. M.; Perestrelo, Rosa; Rocha, Sílvia M.Chromatography was born approximately one century ago and has undergone outstanding technological improvements in innovation, research, and development since then that has made it fundamental to advances in knowledge at different levels, with a relevant impact on the well-being and health of individuals. Chromatography boosted a comprehensive and deeper understanding of the complexity and diversity of human–env...
Elderberry Stalks as a Source of High-Value Phytochemical: Essential Minerals a...
Patinha, Samuel; Murteira, Juliana V.; Costa, Carina Pedrosa; Salvador, Ângelo C.; Santos, Sónia A.O.; Silvestre, A.J.D.; Rocha, Sílvia M.Elderberry (Sambucus nigra L.) consumption has been growing in the last years, generating a large number of stalks (~10% of the berries bunch) that are still under-valorized. This study focused on the evaluation of elderberry stalks as a source of high-value phytochemicals. In this vein, the essential mineral content and lipophilic composition were analyzed for the first time. In addition, the polar fraction wa...

Purple passion fruit (Passiflora edulis f. edulis): a comprehensive review on t...
Fonseca, Alexandre M.; Geraldi, Marina V.; Junior, Mário R. Maróstica; Silvestre, Armando J. D.; Rocha, Sílvia M.Passiflora is a highly diverse genus where taxonomic lack of consensus remains. This may be the reason why numerous studies do not specify to the infraspecific level the plant material used or lack consistency in the nomenclature of botanical formae of Passiflora edulis. Ultimately, this may contribute to inaccurate chemical composition and health effects attributed to different Passiflora edulis species and fo...
Sustainable Valorization of Sambucus nigra L. Berries: From Crop Biodiversity t...
Costa, Carina Pedrosa; Patinha, Samuel; Rudnitskaya, Alisa; Santos, Sónia A. O.; Silvestre, Armando J. D.; Rocha, Sílvia M.Improvement of dietary and ecological biodiversity, namely by exploring autochthonous varieties, is a key point to the construction of a more sustainable food system and planetary health. However, the environmental sustainability continues to face huge challenges, reflecting the importance of achieving a better understanding about the functional role of biodiversity in ecosystems. Thus, the main objective of th...
Cinnamomum burmannii decoction: a thickening and flavouring ingredient
Nunes, Cláudia; de J. Raposo, M. Filomena; Petronilho, Sílvia; Machado, Fernanda; Fulgêncio, Rita; Gomes, M. Helena; Evtuguin, Dmitry V.Cinnamon is a spice widely used as a flavouring agent in foodstuffs. Despite its commercial availability and low cost, C. burmannii aqueous extracts obtained by decoction originate high viscous solutions (1545 cP) when compared with C. verum (51 cP), preventing its broad use by food industry. Following the hypothesis that cinnamon polysaccharides are responsible for this viscosity, in this work, the hot water-s...
Metabolic Phenotypes in Asthmatic Adults: Relationship with Inflammatory and Cl...
Santos, Adalberto; Pité, Helena; Loureiro, Cláudia Chaves; Rocha, Sílvia M.; Taborda-Barata, LuísBronchial asthma is a chronic disease that affects individuals of all ages. It has a high prevalence and is associated with high morbidity and considerable levels of mortality. However, asthma is not a single disease, and multiple subtypes or phenotypes (clinical, inflammatory or combinations thereof) can be detected, namely in aggregated clusters. Most studies have characterised asthma phenotypes and clusters ...
Chemical characterization of Sambucus nigra L. flowers aqueous extract and its ...
Ferreira-Santos, P.; Costa, H.; Salvador, Ângelo C.; Silvestre, Armando J. D.; Santos, Sónia A. O.; Rocha, Sílvia M.; Sousa, Ana MargaridaThe main goal of this study was to chemically characterize an aqueous S. nigra flower extract and validate it as a bioactive agent. The elderflower aqueous extraction was performed at different temperatures (50, 70 and 90 °C). The extract obtained at 90 °C exhibited the highest phenolic content and antiradical activity. Therefore, this extract was analyzed by GC-MS and HPLC-MS, which allowed the identification ...
