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...
Lemna minor: unlocking the value of this duckweed for the food and feed industry
Sosa, Diana; Alves, Felipe M.; Prieto, Miguel A.; Pedrosa, Mariana C.; Heleno, Sandrina A.; Barros, Lillian; Feliciano, Manuel; Carocho, MárcioDuckweed (Lemna minor L.) is a small floating aquatic plant that has an important economic impact in several industrial areas. With its high biomass production, reasonable protein content, and resilience to several climates, it has been attracting increasing interest for potential use in animal and human food systems. Historically consumed in southwest Asia, this duckweed is now gaining attention as a potential...
Harnessing the power of natural mineral waters in bread formulations: effects o...
Ferreira, Fernanda; Guimarães, Rafaela; Lemos, André; Milho, Catarina; Silveira, Tayse F. F. da; Ueda, Jonata M.; Carocho, Márcio; Heleno, Sandrina A.This study aimed to evaluate the feasibility of incorporating natural mineral waters (NMW), including thermal water (TW) and bottled mineral water (BMW), into bread (‘biju’ type) to enhance its mineral content and explore their impacts on physicochemical, technological, biochemical, and chemical composition. NMW, rich in sodium, potassium, and magnesium, resulted in bread formulations with higher contents of th...
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...
Development, characterization and stability of a novel sport drink based on the...
Radhouane, Maroua Fatma; Silveira, Tayse Ferreira; Ribeiro, Jessica; Rodrigues, Paula; Guimarães, Rafaela; Calhelha, Ricardo C.; Mandim, FilipaIsotonic drinks are sports beverages that replenish minerals and rapidly absorbable carbohydrates. We proposed to surpass traditional formulations of isotonic drinks by integrating thermal water, which remains unexploited as a source of electrolytes in isotonic despite the high mineral content. The novel formula combined thermal water with apple juice and hibiscus extract (as sources of sugars and color, respec...
Extraction of Bioactive Compounds from Rubus Idaeus Bioresidues: A Full Screeni...
Plasencia, Paula; Finimundy, Tiane C.; Carocho, Márcio; Calhelha, Ricardo C.; Añibarro-Ortega, Mikel; Pires, Tânia C.S.P.; Barreiro, FilomenaPurpose Rubus idaeus cultivation has boosted productivity due to its high nutritional value. In consequence, waste produc- tion increased. The discarded biomass, including leaves and aerial components, can be transformed into valuable functional ingredients for industrial applications, such as cosmetics. Studying their bioactivity potential is highly relevant. Methods According to the present idea, the research...
