Optimization of heat and ultrasound-assisted extraction of Eucalyptus globulus ...
Lima, Laíres; Pereira, Ana I.; Vaz, Clara B.; Ferreira, Olga; Dias, Maria Inês; Heleno, Sandrina A.; Calhelha, Ricardo C.; Barros, LillianThe extraction of phenolic compounds from eucalyptus leaves was optimized using heat and ultrasound-assisted techniques, and the bioactive potential of the resulting extract was assessed. The independent variables, including time (t), solvent concentration (S), and temperature (T) or power (P), were incorporated into a fivelevel central composite design combined with Response Surface Methodology. Phenolic conte...
Blockchain revolution in food supply chains: A positive impact on global food l...
Shiraishi, Carlos Seiti Hurtado; Roriz, Custódio Lobo; Carocho, Márcio; Prieto Lage, Miguel A.; Abreu, Rui M.V.; Barros, Lillian; Heleno, Sandrina A.The rising global population has created an urgent need for increased food production. Food loss and waste remain significant challenges throughout the food supply chain, from cultivation to consumption. Blockchain, a decentralized peer-to-peer network that stores information can help making food more traceable, from production to consumption. It can also help enhance food production sustainability, transparenc...
Phenolic Compounds from Pyrus communis Residues: Mechanisms of Antibacterial Ac...
Ribeiro, Jessica; Silva, Vanessa; Igrejas, Gilberto; Barros, Lillian; Heleno, Sandrina A.; Reis, Filipa S.; Poeta, PatríciaThe food industry produces substantial amounts of fruit byproducts, which are often discarded despite their high content of bioactive compounds with potential therapeutic applications. Pyrus communis (pear) residues, which are particularly rich in phenolic compounds, represent a valuable yet underutilized resource. These byproducts have demonstrated significant antioxidant and antibacterial properties, suggesti...
Valorization of natural resources - development of a functional plant-based bev...
Fernandes, Filipa Alexandra; Roriz, Custódio Lobo; Calhelha, Ricardo C.; Rodrigues, Paula; Pires, Tânia C.S.P.; Prieto Lage, Miguel A.Plant-based beverages are gaining attention due to their potential to offer sustainable and health-promoting alternatives to traditional dairy products. This study aimed to develop a dehydrated functional plant-based beverage composed of tigernut tubers (Cyperus esculentus L.), mukua pulp (Adansonia digitata L.), and thermal water. All matrices and the final beverage were fully characterized in terms of physica...
Bio-Recycling Hazelnut Shells to Improve Antioxidant Properties of Lentinus tig...
Desiderio, Anthea; Pedrosa, Mariana C.; Heleno, Sandrina A.; Carocho, Márcio; Rodrigues, Daniele Bobrowski; Buratti, Simone; Soffientini, IreneLentinus tigrinus is a wood-decay fungus known for its nutritional, culinary, and medicinal benefits. It contains bioactive compounds like polyphenols, terpenes, and flavonoids that exhibit antioxidant, anti-microbial, and anti-inflammatory effects. These natural antioxidants are increasingly recognized for their potential to prevent oxidative damage linked to aging and chronic diseases. This study investigates...
An update on fermented plant-based dairy alternatives: advances towards consume...
Ueda, Jonata Massao; Fernández-Ruiz, Virginia; Morales, Patricia; Ferreira, Anabela; Heleno, Sandrina A.; Carocho, MárcioPlant-based dairy alternatives (PBDA) represent a significant portion of the consumption of plant-based products, mainly to replace or complement the diet in relation to dairy milk, due to their health properties, the absence of lactose, environmental impacts, and consumer preference. These products have attracted a wide range of consumers, as they can be derived from different plant sources such as soy, rice, ...
Banana Peels as Substrate for Lactic Acid Production: Upstream Fermentation Bio...
Pedrosa, Mariana C.; Heleno, Sandrina A.; Alvarez, Cristina; Susmozas, Ana; Ballesteros, Ignacio; Pintado, Manuela; Barros, Lillian; Carocho, MárcioPurpose Banana peels account for around 30-40% of the banana's weight and represent an industrial waste. This biomass can be used as an eco-friendly solution for biotechnological bioprocesses. Still, due to the fibrous nature of banana peels, pretreatment becomes essential to enhance the effectiveness of enzymes on the hydrolysis of complex carbohydrates. This study aims to determine the best pretreatment and e...
From Apple Waste to Antimicrobial Solutions: A Review of Phenolics from PGI ‘Ma...
Ribeiro, Jessica; Silva, Vanessa; Dapkevicius, Maria de Lurdes N. E.; Igrejas, Gilberto; Barros, Lillian; Heleno, Sandrina A.; Reis, Filipa S.Apple by-products represent a valuable source of phenolic compounds with significant antimicrobial potential, aligning with sustainable strategies for waste valorisation within the circular bioeconomy. This review focuses on the phenolic profile and antimicrobial relevance of ‘Maçã de Alcobaça,’ a Protected Geographical Indication (PGI) apple variety from Portugal. The main phenolics identified include phloridz...
Genomic Analysis of Antibiotic Resistance and Virulence Profiles in Escherichia...
Ribeiro, Jessica; Silva, Vanessa; Freitas, Catarina; Pinto, Pedro; Vieira-Pinto, Madalena; Batista, Rita; Nunes, Alexandra; Gomes, João PauloSternal bursitis is an underexplored lesion in poultry, often overlooked in microbiological diagnostics. In this study, we characterized 36 Escherichia coli isolates recovered from sternal bursitis in broiler chickens, combining phenotypic antimicrobial susceptibility testing, PCR-based screening, and whole genome sequencing (WGS). The genetic analysis revealed a diverse population spanning 15 sequence types, i...
Nutritional and Bioactive Characterization of Unconventional Food Plants for Su...
Oliveira, Izamara; Salgado, José Miguel R.T.; Lopes, João Pedro Krauspenhar; Carocho, Márcio; Silveira, Tayse F. F. da; Garcia, Vitor Augusto dos SantosUnconventional food plants (UFPs) are increasingly valued for their nutritional composition and bioactive potential. This study proposes a comprehensive characterization of the chemical and bioactive properties of Pereskia aculeata Miller (Cactaceae) (PA); Xanthosoma sagittifolium (L.) Schott (Araceae) (XS); Stachys byzantina K. Koch (Lamiaceae) (SB); and inflorescences from three cultivars of Musa acuminata (M...
