Exploring the potential of invasive species Sargassum muticum: microwave-assist...
Silva, Aurora; Cassani, Lucia; Carpena, Maria; Lourenço-Lopes, Catarina; Grosso, Clara; Chamorro, Franklin; García-Pérez, Pascual; Carvalho, AnaSargassum muticum (SM) poses a serious environmental issue since it is a fast-expanding invasive species occupying key areas of the European shoreline, disrupting the autochthonous algae species, and disturbing the ecosystem. This problem has concerned the general population and the scientific community. Nevertheless, as macroalgae are recognized as a source of bioactive molecules, the abundance of SM presents ...
Pigment composition of nine brown algae from the iberian northwestern coastline...
García-Pérez, Pascual; Lourenço-Lopes, Catarina; Silva, Aurora; González Pereira, Antía; Fraga-Corral, Maria; Zhao, Chao; Xiao, JianboBrown algae are ubiquitously distributed in the NW coastline of the Iberian Peninsula, where they stand as an underexploited resource. In this study, five solvents were applied to the extraction of pigments from nine brown algae, followed by their determination and quantification by HPLC-DAD. A total of 13 compounds were detected: Six were identified as chlorophylls, six were classified as xanthophylls, and one...
Thermochemical characterization of eight seaweed species and evaluation of thei...
Cassani, Lucia; Lourenço-Lopes, Catarina; Barral Martínez, Marta; Chamorro Rivo, Franklin Noel; García-Pérez, Pascual; Simal-Gandara, JesusAlgae are underexplored resources in Western countries and novel approaches are needed to boost their industrial exploitation. In this work, eight edible seaweeds were subjected to their valorization in terms of nutritional characterization, thermochemical properties, and bioactive profile. Our results suggest that seaweeds present a rich nutritional profile, in which carbohydrates are present in high proportio...
Biological properties and potential of compounds extracted from red seaweeds
Carpena Rodríguez, María; García-Pérez, Pascual; García-Oliveira, Paula; Chamorro Rivo, Franklin Noel; Otero, Paz; Lourenço-Lopes, Catarina; Cao, HuiMacroalgae have been recently used for different applications in the food, cosmetic and pharmaceutical industry since they do not compete for land and freshwater against other resources. Moreover, they have been highlighted as a potential source of bioactive compounds. Red algae (Rhodo- phyta) are the largest group of seaweeds, including around 6000 different species, thus it can be hypoth- esized that they are...
By-products of walnut (Juglans regia) as source of bioactive compounds for the ...
Chamorro Rivo, Franklin Noel; Carpena Rodríguez, María; Lourenço-Lopes, Catarina; Taofiq, Oludemi; Otero, Paz; Cao, Hui; Xiao, JianboThe scarcity of natural resources and a higher incidence of diseases related to inappropri-ate eating habits have focused research on the search for food and nutraceutical products with func-tional properties that are respectful of the environment. Agro-industrial by-products are a profitable source for obtaining bioactive compounds, with various biological properties, including antioxi-dant, anti-inflammatory,...
A HPLC‐DAD method for identifying and estimating the content of fucoxanthin, β‐...
Lourenço-Lopes, Catarina; Fraga-Corral, Maria; Garcia-Perez, Pascual; Carreira-Casais, Anxo; Silva, Aurora; Simal-Gandara, Jesus; Prieto Lage, Miguel A.Seaweeds are photosynthetic organisms that have high contents of pigments. The coloration of each alga is defined by the content and combination of pigments synthesized, which varies among species and environmental condi- tions. The most abundant pigments in algae are chlorophylls and carotenoids, lipophilic molecules that can be used as natural colorants and have high acceptance by consumers. In this work, a s...

Fucoxanthin’s Optimization from Undaria pinnatifida Using Conventional Heat Ext...
Lourenço-Lopes, Catarina; Fraga-Corral, Maria; Soria-Lopez, Anton; Nuñes-Estevez, Bernabe; Barral-Martinez, Marta; Silva, Aurora; Li, NingyangBrown macroalgae are a potential source of natural pigments. Among them, Undaria pinnatifida is recognized for its high concentration of fucoxanthin (Fx), which is a pigment with a wide range of bioactivities. In this study, three independent parameters were optimized for conventional heat extraction (CHE) to maximize the recovery of Fx from Undaria pinnatifida. Optimal conditions (temperature = 45 °C, solvent ...

Evolution of flavors in extra virgin olive oil shelf-life
García-Oliveira, Paula; Jiménez López, Cecília; Lourenço-Lopes, Catarina; Chamorro Rivo, Franklin Noel; González Pereira, Antía; Carreira Casais, AnxoExtra virgin olive oil (EVOO) is one of the most distinctive ingredients of the Mediterranean diet. There are many properties related to this golden ingredient, from supreme organoleptic characteristics to benefits for human health. EVOO contains in its composition molecules capable of exerting bioactivities such as cardio protection, antioxidant, anti-inflammatory, antidiabetic, and anticancer activity, among ...
