The present work aimed at studying Saccorhiza polyschides extracts obtained by subcritical water extraction as a potential source of essential macro and trace elements, aiming for its application biofertilizer. mineral composition, well sulfate, chlorine iodine, total organic matter, nitrogen content, were determined on the from seaweeds harvested during low tide northern Portuguese coast. selected parameters are important Among macronutrients, most abundant was K (15.7 ± 0.2 g/L), followed...
Mental health and active aging are two of the main concerns in 21st century. To search for new neuroprotective compounds, extracts Codium tomentosum Stackhouse Fucus vesiculosus L. were obtained through multi-step (four step) subcritical water extraction using a temperature gradient. The safety assessment was performed by screening pharmaceutical compounds pesticides UHPLC-MS/MS, iodine arsenic levels ICP-MS. Although free pesticides, presence high contents found first steps. Thus,...
This presents the efficacy of a 3D-ElectroFenton (3D-EF) reactor with active perovskite/carbon black/PTFE microelectrodes for removal carbamazepine (CZP) present in wastewater. Incorporating particle enhanced electron transfer and improved electrocatalytic efficiency, leading to more effective CZP removal. The optimal operational conditions were meticulously determined, including current intensity (0.05 – 0.3 A) loading (0 1.5 g), optimize process minimize energy consumption. findings reveal...
Abstract BACKGROUND Morus nigra (mulberry) fruit has been reported as a source of bioactive compounds, although information about their leaves is very limited. Usually, they are considered wastes and have traditionally used only for tea preparation. The main objective this work was to explore the valorization mulberry by polyphenols microwave‐assisted extraction (MAE) characterization antioxidant activity phenolic composition. A 2 3 factorial design combined with response surface methodology...
The three-dimensional (3D) electrochemical treatment process was studied for the removal of two pharmaceuticals, diclofenac (anti-inflammatory) and sulfamethoxazole (antibiotic), in mono bi-component systems. Adsorption conventional two-dimensional processes were initially then combined to develop 3D process. influence different operating parameters on efficiency studied: distance between cathode anode, pharmaceutical electrolyte (NaCl) concentrations, pH, (carbon-based) adsorbent used as...
This study aimed to optimize the extraction conditions for a valuable source of antioxidants: seaweed. Therefore, ten seaweed samples were subjected solid–liquid (SLE), where (biomass (g): solvent (mL) ratio, temperature, and time) optimized using response surface methodology (RSM). The seaweeds also subcritical water (SWE) (140 190 °C) ultrasound-assisted (UAE) (10 20 min). antioxidant capacity extracts was determined through ferric-reducing power...
Sericin has been characterized as demonstrating a variety of bioactivities, establishing it valuable resource for biomedical and pharmaceutical applications. The diverse biological activities sericin are likely linked to its unique biochemical composition properties. This study aimed assess the effect origin, seasonality, amino acid on bioactivity samples from two Portuguese regions compared commercial sericin. profile was analyzed using HPLC-FLD. Moreover, several bioactivities were...
Veganism is gaining popularity due to its ethical, health, and environmental benefits. However, many vegans face challenges in obtaining a complete essential amino acid profile from plant sources, making diversified protein sources crucial for balanced nutrition. Macroalgae, nutrient-rich food traditionally consumed Asia, offers solution by providing both non-essential acids vital optimal health. This study analyzed the profiles of seven macroalgae species northwest coast Iberian Peninsula...
The main objective of this study was to provide an overview the potential health-promoting properties honeys collected at specific apiary locations from protected area Montesinho Natural Park (MNP), by analyzing their amino acid and polyphenolic profiles, biological properties, comparing them with renowned Manuka honey. results revealed differences in total phenolic content among samples examined between sampling campaigns, values ranging 55.6 225 mg gallic equivalents (GAE) per 100 g honey,...
Marine macroalgae are excellent sources of bioactive compounds recognized by their pharmaceutical and biomedical potential. A subcritical water extraction (SWE) was applied to the macroalga Codium tomentosum, extract used prepare phytosomes. Box–Behnken design optimize entrapment efficiency. These phytosomes were further modified with DSPE-PEG (2000)-maleimide apolipoprotein E characterized dynamic light scattering, UV spectrophotometry, octanol/water partition coefficient, differential...
An improved gas chromatography-mass spectrometry (GC-MS) method to determine acrylamide (AA) in coffee and products was developed. The based on two main purification steps: the first with ethanol Carrez solutions order precipitate polysaccharides proteins, respectively; second a layered solid-phase extraction (SPE) column which proved be efficient elimination of chromatographic interferences. is applicable wide range products. Twenty-six samples different were analysed. levels AA 11.4-36.2...
The present study describes the development and validation of a new method based on matrix solid-phase dispersion (MSPD) sample preparation procedure followed by GC-MS for determination acrylamide levels in coffee (ground brewed coffee) substitute samples. Samples were dispersed C(18) sorbent mixture was further packed into preconditioned custom-made ISOLUTE bilayered SPE column (C(18)/Multimode; 1 g + g). Acrylamide subsequently eluted with water, then derivatized bromine quantified SIM...
