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...
Investigating bioactive compounds in apple pomace: Potential to develop high ad...
Pascoalino, Liege; Finimundy, Tiane C.; Pires, Tânia C.S.P.; Pereira, Carla; Barros, Lillian; Ferreira, Isabel C.F.R.; Oliveira, BeatrizThis study investigates bioactive compounds in apple pomace (AP) obtained from Malus domestica varieties Granny Smith and Cripps Pink, emphasizing its potential for developing high-added-value products from industrial surplus. Regarding its chemical characterization, AP stood out for its high concentration of dietary fibers (7.1g/100g fw), polyunsaturated fatty acids (linoleic and oleic acids), α-tocopherol (0....
Nutritional, Chemical, Antioxidant and Antibacterial Screening of Astragalus ci...
Shahrivari-Baviloliaei, Saba; Konopacka, Agnieszka; Pascoalino, Liege; Reis, Filipa S.; Kunkowski, Dawid; Petropoulos, Spyridon A.; Konieczynski, PawelThe chemical composition and biological activity of A. glycyphylos and A. cicer are scarcely investigated. In this study, the nutritional and chemical profiles of A. cicer and A. glycyphyllos, considering their different morphological parts (leaves, fruits and roots), were assessed together with their antioxidant and antibacterial potential. Our results showed that carbohydrates are the major macronutrients in ...
Closing the loop: exploring apple pomace as a source of bioactive compounds in ...
Pascoalino, Liege; Barros, Lillian; Barreira, João C.M.; Oliveira, Beatriz; Reis, Filipa S.Apple pomace (AP), the common designation of bio-residues generated during apple processing, holds a vast potential for alternative added-value solutions, particularly by applying new sustainable technologies in the food sector. This review provides an overview of the scientific validation of AP as a suitable source of starting materials for different competitive applications, compatible with circular economy g...
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...
Foliar application of biostimulants improves nutritional and bioactive quality ...
Pascoalino, Liege; Pires, Tânia C.S.P.; Pinela, José; Rodrigues, M.A.; Ferreira, Isabel C.F.R.; Barros, Lillian; Barreira, João C.M.; Reis, Filipa S.Owing to their health benefits, walnuts are attracting interest as a good option for nutritious meals, thereby promoting their production. Furthermore, the adoption of ecologically and environmentally friendly agriculture strengthens biostimulant use as a sustainable complement to traditional fertilizers. This study evaluated the effects of different foliarapplied biostimulants in walnut tree orchards, in north...
How Does Domestic Cooking Affect the Biochemical Properties of Wild Edible Gree...
Liava, Vasiliki; Fernandes, Ângela; Reis, Filipa S.; Finimundy, Tiane C.; Mandim, Filipa; Pinela, José; Stojković, Dejan; Ferreira, Isabel C.F.R.Wild edible greens are a key ingredient of the so-called Mediterranean diet and they are commonly used in various local dishes in their raw or processed form. Domestic processing of edible greens may affect their nutritional value and chemical profile. In this work, six wild species (e.g., Cichorium spinosum L. (S1); Centaurea raphanina subsp. mixta (DC.) Runemark (S2); Picris echioides (L.) Holub (S3); Urosper...
Value-added lipids from plant foods and respective applications
Pedrosa, Mariana C.; Ueda, Jonata Massao; Heleno, Sandrina A.; Carocho, Márcio; Reis, Filipa S.; Ferreira, Isabel C.F.R.; Barros, LillianSince ancient times, man has used plants as a food source, associating their consumption with nutritional and health benefits. Among the nutrients obtained from plants, which the consumer associates more with beneficial health effects than those obtained from the animal diet, we can highlight the lipids. Lipids play a vital role in plant or animal biology, as they are a source of energy and can also act as horm...
Plant extracts and SARS-CoV-2: research and applications
Heleno, Sandrina A.; Carocho, Márcio; Reis, Filipa S.; Pires, Tânia C.S.P.; Pintado, Manuela; Ferreira, Isabel C.F.R.; Barros, LillianThe recent pandemic of COVID-19 caused by the SARS-CoV-2 virus has brought upon the world an unprecedented challenge. During its acute dissemination, a rush for vaccines started, making the scientific community come together and contribute to the development of efficient therapeutic agents and vaccines. Natural products have been used as sources of individual molecules and extracts capable of inhibiting/neutral...
