Magnesium and manganese induced changes on chemical, nutritional, antioxidant a...
Oliveira, Izamara; Chrysargyris, Antonios; Finimundy, Tiane C.; Carocho, Márcio; Santos-Buelga, Celestino; Calhelha, Ricardo C.; Tzortzakis, Nikolaoscomposition was determined using standard methods. Free sugars, fatty acids, organic acids, tocopherols, and phenolic compounds were analyzed using various HPLC and GC devises. The extract’s antimicrobial, antioxidant, cytotoxicity, and anti-inflammatory activity were assessed. The results indicated that Mg enrichment negatively affected plant growth and mineral accumulation but improved photosynthetic performa...
Recovery of anthocyanins from Eugenia spp. fruit peels: a comparison between he...
Albuquerque, Bianca R.; Pinela, José; Pereira, Carla; Mandim, Filipa; Heleno, Sandrina A.; Oliveira, Beatriz; Barros, LillianNatural colorants have gained increased popularity among consumers and food producers due to their reputation as safer and healthier alternatives to commonly used artificial analogues. These natural pigments can be obtained from by-products resulting from food processing, such as the fruit peels of the Brazilian species Eugenia brasiliensis and Eugenia involucrata, thus contributing to the valorisation and circ...
Response surface methodology applied to ultrasound-assisted extraction of raspb...
Plasencia, Paula; Carocho, Márcio; Heleno, Sandrina A.; Finimundy, Tiane C.; Barreiro, M.F.; García, Pablo A.; Barros, LillianDue to their high nutritional value, berries production has increased, but this inevitably leads to the accumulation of bioresidues. To prevent this, leaves and other aerial components of berry plants can be converted into valuable ingredients for cosmetics applications due to their unique chemical composition and functional properties. Ultrasound-assisted extraction methodology is an efficient technique to obt...
Chemical characterization and bioactive properties of wine lees and diatomaceou...
Duarte, Cristina Nogueira; Taofiq, Oludemi; Dias, Maria Inês; Heleno, Sandrina A.; Santos-Buelga, Celestino; Barros, Lillian; Amaral, Joana S.Annually, wine production is responsible for generating large quantities of residues, which are frequently disposed of and not valorized. So far, different studies have been conducted on grape pomace, yet less attention has been paid to other residues, such as wine lees and diatomaceous earth used in wine filtration. In this context, this study aimed to evaluate and compare the phenolic profile of these underex...
The generally recognized as safe (GRAS) microalgae Haematococcus pluvialis (wet...
Castillo, Aly; Finimundy, Tiane C.; Heleno, Sandrina A.; Rodrigues, Paula; Fernandes, Filipa Alexandra; Pereira, Simón; Lores, Marta; Barros, LillianThis work proposes the application of astaxanthin-rich H. pluvialis wet paste (HPW) as a partial substitute for wheat flour in the preparation of filloas, a dish that combines the basic ingredients of industrial bakery. The nutritional and color profile of HPW-enriched samples was evaluated by comparative analysis with a mixture of synthetic food dyes. The highest content of carotenoids (798 ± 12 µg g−1) and fatty...
Recovery of high valuable bioactive molecules from Vaccinium myrtillus L. biore...
Plasencia, Paula; Heleno, Sandrina A.; Finimundy, Tiane C.; Carocho, Márcio; Calhelha, Ricardo C.; Añibarro-Ortega, Mikel; Alves, Maria JoséPurpose The interest in using bioresidues produced by the agri-food industry is increasingly intrinsic to the world economy. As such, researchers started to look for new ways to enhance its use, developing innovations to transform these residues into high-value raw materials with industrial application, promoting the circular economy concept. Methods Therefore, pruning residues from the production of Vaccinium ...
Powdered foods: structure, processing, and challenges: a review
Ueda, Jonata Massao; Morales, Patricia; Fernandez-Ruiz, Virginia; Ferreira, Anabela; Barros, Lillian; Carocho, Márcio; Heleno, Sandrina A.Powdered foods are easy to store and transport, with a longer shelf life that minimizes potential waste, contributing to sustainable development. Each food category has a unique composition, responsible for its chemical and physical attributes, which directly influences the stability of powdered products. The drying method used is essential to obtain the desired characteristics of the powdered food, and the cho...
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...
Inflammation: what's there and what's new?
Calhelha, Ricardo C.; Haddad, Hala; Ribeiro, Lucia M.; Heleno, Sandrina A.; Carocho, Márcio; Barros, LillianSince the dawn of man, inflammation has been known to humanity, as it is marked by pain. Inflammation processes are related to serious chronic diseases with irreversible damage to the organism, being crucial for the development of anti-inflammatory agents. Among the existing anti-inflammatory drugs, non-steroidal and glucocorticoids are commonly used; however, these compounds have been described as responsible ...
