Exploring the effects of sweet potato leaves on skin health - from antimicrobia...
Machado, Manuela; Silva, Sara; Pintado, Manuela; Costa, Eduardo M.Sweet potato leaves (SPL), an agricultural byproduct, hold significant potential in dermatological applications due to their bioactive compounds. This study evaluates the phenolic profile of SPL extracts and investigates their biological activities relevant to skin health. Extract fingerprinting, through uHPLC-DAD and LC–MS, identified phenolic acids and flavonoids, with cynarin, neochlorogenic acid, and spirae...
Alginate edible films containing essential oils: characterization and bioactive...
Lopes, Ana I.; Melo, Adma; Afonso, Tiago B.; Silva, Sara; Barros, Lillian; Tavaria, Freni K.; Pintado, ManuelaEssential oils (EOs) are natural substances rich in phenolic compounds with notable antimicrobial and antioxidant properties. However, they present some limitations, such as low stability and bioavailability. Incorporating EOs into polymeric films offers a novel approach to overcome these challenges while enhancing their efficacy. In this study, we produced and thoroughly characterized alginate-based edible fil...
Application of encapsulated tomato by-product extract as a colorant in mascarpone
Molina, Adriana K.; Leichtweis, Maria G.; Machado, Manuela; Silva, Sara; Pintado, Manuela; Barreira, João C. M.; Dias, Maria Inês; Prieto, Miguel Á.Agricultural by-products, often underutilized, represent a significant opportunity to obtain sustainable value-added products to develop new functional foods. In this context, the (typically discarded) aerial parts of tomato plants (Solanum lycopersicum L. var. cerasiforme), were studied as new sources of natural bioactive compounds, focusing the extraction and encapsulation (using spray drying with maltodextri...
Soft gels in food systems: recent advances, applications, and technological inn...
Machado, Manuela; Costa, Eduardo Manuel Aguiar da; Silva, SaraSoft gels, such as hydrogels, organogels, aerogels, and bigels, represent versatile materials that are increasingly utilized within food systems to modify texture, regulate nutrient delivery, serve as fat substitutes, and enhance product shelf life. Their structural diversity and tunable properties enable targeted solutions for healthier, more sustainable, and consumer-centric products. This review provides a c...
Bioactive food proteins: bridging nutritional and functional benefits with sust...
Machado, Manuela; Bautista-Hérnandez, Israel; Gómez-García, Ricardo; Silva, Sara; Costa, Eduardo M.Bioactive food proteins play multifunctional roles in human health and functional food development. Beyond their nutritional value, these proteins contain peptide sequences capable of exerting physiological effects, such as antioxidant, anti-hypertensive, immunomodulatory, and anti-inflammatory activities. This review summarises the processing and functional technologies applied to bioactive proteins; the incre...

Normative values and reference equations of the 4-meter gait speed test for Por...
Silva, Sara; Vilarinho, Rui; Festas, Clarinda; Santos, Fátima; Montes, António Mesquita; Jácome, Cristina; Mesquita Montes, António; Vilarinho, RuiTo determine the normative values and reference equations of the 4-Meter Gait Speed Test (4MGS) at usual and maximal speed for Portuguese adults. We also assessed the participant experience during the performance of the 4MGS. A cross-sectional study was conducted with individuals without disabilities. Sociodemographic, anthropometric, smoking habits and physical activity (Brief Physical Activity Assessment Tool...
Precision fermentation as a tool for sustainable cosmetic ingredient production
Silva, Sara; Bautista-Hérnandez, Israel; Gomez-García, Ricardo; Costa, Eduardo M.; Machado, ManuelaPrecision fermentation, a highly controlled process of microbial fermentation, is emerging as a transformative tool to produce cosmetic ingredients. This technology leverages engineered micro-organisms to produce high-value compounds with applications in skincare, hair care, and other cosmetic formulations. Unlike traditional methods of ingredient sourcing, which often rely on extraction from plants or animals,...
Thermally processed eggshells as a renewable source of calcium carbonate for in...
Silva, Sara; Marçal, Sara; Ribeiro, Tânia; Pintado, ManuelaCalcium carbonate (CaCO?) is a vital industrial material used extensively in pharmaceuticals, food production, construction, and environmental remediation. Current CaCO? sourcing methods, primarily reliant on mining limestone and chalk, present significant environmental challenges, including habitat destruction, high energy consumption, and carbon emissions. To address these concerns, this study explores the po...
