The interest in the consumption of health-promoting foods has led to identifying derivatives wine industry as products increase functional properties different or design new foods. main goal this study is characterize and valorize byproducts wastes Sicilian grapes sources bioactive components, from perspective a circular economy biorefinery approach. In particular, research investigated: 1. total phenolic content antioxidant activities 2. profiles free bound fractions defatted grape seeds...
In recent years, the invasive Atlantic blue crab (Callinectes sapidus) has increased its spread throughout Mediterranean Sea, threatening native biodiversity and local economies. This study aimed to valorize C. sapidus sampled in Sicily by utilizing exoskeleton as a source of chitosan, astaxanthin, bio-phenolic compounds. These biomolecules were evaluated for their reducing, radical scavenging, antitumor activity. The ferric ion reducing antioxidant power (FRAP) free scavenging activity...
The phenolic profiles of six varieties avocado (Persea americana) grown in Sicily were investigated. ultra-high-performance liquid chromatography-heated electrospray-mass spectrometry method was developed to determine qualitative and quantitative changes fruits at two different ripening stage. Nineteen individual compounds detected pulp extracts. Gallic acid, sinapinic vanillin, p-coumaric gentisic acid present only ripe fruits. On the contrary, epicatechin decreased with fruit ripening,...
Pomegranate fruits are a rich source of polyphenols with numerous health-promoting effects. juices five genotypes ('Mollar', 'Kingdom', 'Dente di Cavallo', and two old populations 'Francofonte' 'Santa Tecla') were evaluated regarding anthocyanin non-anthocyanin phenolic contents using ultrahigh performance liquid chromatography (UHPLC)-Orbitrap-mass spectrometry (MS). Moreover, total antioxidant activity (TAA) was 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS)...
This study aimed to perform an in-depth investigation of olive oil mill wastewater (OOMW). Two OOMW samples (OOMW-A and OOMW-B) from conventionally farmed olives were collected two different mills in Palermo province (Italy). Multiresidual analysis indicated that both unsuitable for food production due pesticide residues. Specifically, OOMW-A contained 4 active compounds totaling 5.7 μg/L, while OOMW-B had 16 analytes with a total content 65.8 μg/L. However, polyphenol the revealed 23 high...
In this work, a new sensitive analytical method has been developed and evaluated for the determination of most commonly used gaseous anesthetics, desflurane, sevoflurane, latter's hepatic metabolite hexafluoroisopropanol (HFIP) in urine. addition, an evaluation anesthetics exposition on urine levels small population surgical operators performed results are briefly discussed.
Among the Sicilian economic productive sectors, that of wine production has today a considerable value. However, with growth this sector, notable was increase in waste, which to date is not only an damage for companies, but also threat environment. It known waste from properties (e.g., antioxidants) have potential reuse at cosmetic, pharmaceutical and nutritional levels obtain economically sustainable applications. A new goal given by recovery added value compounds agri-food wastes...
The raw cladode of Opuntia ficus indica (OFI) was evaluated as a sustainable biosorbent for the removal heavy metals (Ni, Pb, Cu, and Cd) from aqueous solutions. functional groups OFI were identified by employing DRIFT-FTIR CP-MAS-NMR techniques before after contact with ions in an media, showing rearrangement biomass structure due to complexation between metal groups. adsorption process studied both single- multi-component systems under batch conditions at different pHs (4.0, 5.0, 6.0),...
The fatty acid composition of the seed oil from yellow fruit Opuntia ficus‐indica widely grown in Sicily shows several distinctive features. obtained comprises significant amounts vaccenic along with other unsaturated acids showing health benefits, including linolenic, trans ‐13‐octadecenoic, gondoic, 7Z,10Z‐hexadecadienoic, and gadoleic acid. economic analysis advantage carrying out extraction fruits considered unfit for consumption. Practical applications: Sicilian is similar to that...
The aim of this study was to assess the nutraceutical qualities extra virgin olive oil (EVOO) samples obtained from three Sicilian cultivars: Nocellara, Biancolilla, and Cerasuola. We also evidenced relationship among biophenols, base parameters panel test scores, evaluated stability biophenols in EVOO. assessment took into consideration variations harvesting periods influence four different milling methods. A statistical analysis collected data revealed that cultivar period were primary...
Recent observations of X-ray pulsars (XRPs) performed by the Imaging Polarimetry Explorer have made it possible to investigate intricate details these objects in a new way, thanks added value polarimetry. Here we present results member small group XRPs displaying super-orbital variability. was observed three separate times during high state its period. The luminosity 2--8 keV energy band $L $ makes brightest XRP ever We detect significant polarization all observations, with values...
Abstract: The state of melatonin confined in dry cholesterol/lecithin mixed reversed micelles dispersed CCl 4 was investigated using 1 H‐NMR and FT‐IR spectroscopies as a function the to lecithin molar ratio (R MLT ) cholesterol CHL ). An analysis experimental results leads hypothesis that, independent R consequence anisotropic melatonin/lecithin, melatonin/cholesterol interactions, is totally solubilized micelles. Melatonin mainly located oriented nanodomain constituted by hydrophilic...
Abstract A newly developed high‐performance liquid chromatography/mass spectrometry (HPLC/MS) method has been successfully used to analyze plasma concentrations of various phytosterols (cholestanol and β ‐sitosterol) cholesterol metabolites (desmosterol lathosterol). This was based on an unusual solvent combination water/methanol vs. methanol/acetone/ n ‐hexane applied a Purospher Star RP‐18e (125 × 2 mm, 3 µm) column, which proved excellent for the separation, identification quantification...
