Occurrence of emerging persistent and mobile organic contaminants in European water samples
(Elsevier, 2019-01-18)The release of persistent and mobile organic chemicals (PMOCs) into the aquatic environment puts the quality of water resources at risk. PMOCs are challenging to analyze in water samples, due to their high polarity. The ... -
Optimization of a miniaturized solid-phase microextraction method followed by gas chromatography mass spectrometry for the determination of twenty four volatile and semivolatile compounds in honey from Galicia (NW Spain) and foreign countries
(Elsevier, 2021)An analytical miniaturized methodology based on solid-phase-microextraction (mini_SPME) followed by gas chromatography coupled to mass spectrometry (GC-MS) has been developed for the identification of volatile and semivolatile ... -
Paralytic Shellfish Toxins Occurrence in Non-Traditional Invertebrate Vectors from North Atlantic Waters (Azores, Madeira, and Morocco)
(MDPI, 2018)Paralytic shellfish toxins (PSTs) are potent alkaloids of microalgal and cyanobacterial origin, with worldwide distribution. Over the last 20 years, the number of poisoning incidents has declined as a result of the ... -
Peel of traditional apple varieties as a great source of bioactive compounds: extraction by micro-matrix solid-phase dispersion
(MDPI, 2020)Micro matrix solid phase dispersion (micro-MSPD) was optimized by response surface methodology for the extraction of polyphenols from the peel of twelve traditional and eight commercial apple varieties grown in Croatia. ... -
Phenolic Profile of Fruit Industry Byproducts Determined by LC–DAD–MS/MS

Physical Properties and Consumer Evaluation of Cocoa Bean Shell-Functionalized Biscuits Adapted for Diabetic Consumers by the Replacement of Sucrose with Tagatose
(MDPI, 2020)The cocoa bean shell (CBS), a by-product of the cocoa industry, has been reported to be rich in fiber and polyphenols, which could contribute to reducing the metabolism of sugars and glucose adsorption. The production of ... -
Physico-Chemical Characterization of Tunisian Canary Palm (Phoenix canariensis Hort. Ex Chabaud) Dates and Evaluation of Their Addition in Biscuits
(MDPI, 2020)Phoenix canariensis Hort. Ex Chabaud, also known as the Canary Island palm or ornamental palm, is an endemic species of the Canary Islands and has been widely propagated globally. It has become one of the most important ... -
Polyethylene microplastics do not increase bioaccumuation or toxicity of nonylphenol and 4-MBC to marine zooplankton
(Elsevier, 2019-07-08)Global production of synthetic polymers, led by polyethylene (PE), rose steadily in the last decades, and marine ecosystems are considered as a global sink. Although PE is not biodegradable, in coastal areas it fragments ... -
