The aim of this research was to assess the effects fruit purees banana, kiwi, mango, red berry, and strawberry on microbiological, physicochemical, antioxidant, sensory properties sheep yogurt. were characterized for their microbiological profile before yogurt production, no spoilage or pathogenic microorganisms detected in any analyzed. Yogurt productions carried out under industrial conditions using pasteurized sheep's milk selected starter cultures Lactobacillus delbrueckii subsp....
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...
The interest in assessing the behavior of rare-earth elements (REE) natural environment is constantly increasing due to their numerous applications both environmental and technological fields. However, current methodologies for analyzing REE distributions are based on normalization concentration profiles lithological values, potentially resulting different outcomes depending which values used normalization, affecting interpretability data. present work proposes an alternative approach by...
In the present work, oregano essential oils (OEOs) were applied to process fresh ovine cheese "Tuma" obtained by pressed technology. Cheese making trials performed under industrial conditions using ewe's pasteurized milk and two strains of Lactococcus lactis (NT1 NT4) as fermenting agents. Two experimental products (ECP) through addition 100 (ECP100) 200 (ECP200) µL/L OEO milk, while control product (CCP) was OEO-free. Both Lc. showed in vitro vivo ability grow presence OEOs dominate over...
The protonation constants of the polyacrylate anion (molecular mass 2000 Da) in Et4NI, Me4NCl, LiCl, LiNO3, NaCl, NaNO3, and KCl aqueous solution, were determined a wide range ionic strengths. A three-parameter approximation was used to express as function dissociation degree α, their dependence on strength considered using simple polynomial expansion. Differences log KH between different data media interpreted terms weak complex formation alkali metal cations. Measurements also performed at...
Protonation constants of several natural and synthetic humates fulvates were determined by ISE-H+ potentiometry in different ionic media (alkali metal halides tetraethylammonium iodide) at strengths T = 298.15 K. Experimental data obtained previous studies (polyacrylates, polymethacrylates, polyacrylate-co-maleate) naturally occurring (alginate, humic substances) polycarboxylates also taken into account the general analysis acid−base properties polyelectrolytes. expressed as a function...
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),...
Abstract The content of 21 polycyclic aromatic hydrocarbons (PAHs) were determined in 16 samples sediments collected from Ganzirri and Faro marine coastal lagoons Messina, Italy. Analysis was performed by gas chromatography/mass spectrometry (GC/MS) selected ion monitoring (SIM) mode. total concentration (ΣPAHs) ranged 74 to 5755 μg/kg dry matrix. resulting distributions molecular ratios specific compounds are discussed terms sampling location origin organic matter. results obtained show...
Trace metal concentrations were measured in different tissues of Sabella spallanzanii, Styela plicata, and Mytilus galloprovincialis collected the Termini Imerese Harbor (Sicily, Italy) to evaluate potential use these species as bioindicators. Higher bioaccumulation factors (BAFs) calculated tube S. except for As, which had a higher BAF branchial crown same species. Regarding other analyzed, BAFs found digestive gland M. galloprovincialis. An exception was Pb, significantly more concentrated...
The aim of this study was to develop a novel and healthier fermented meat product by replacing pork fat with avocado pulp (AVP) during salami production. Experimental salamis were produced under laboratory conditions substituting AVP partially (10-AVP) totally (20-AVP), while control (CTR) remained AVP-free. microbial composition experimental assessed using combined culture-dependent -independent approach. Over 20-days ripening period, lactic acid bacteria, coagulase-negative staphylococci,...
The content of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn, has been determined in the organic inorganic fraction eight soil samples from Sicily. A modified type-Tessier sequential extraction procedure used to recognize metals five different fractions categorised as follows: (a) exchangeable metals, (b) bound carbonates, (c) iron manganese oxides, (d) matter, (e) residual fraction. mineralogical composition soils was characterized by X-ray diffraction. Humic substances were extracted means an...
The acid-base properties of pectin and its ability to complex with copper(II) or cadmium(II) were quantitatively determined in order define the this natural polyelectrolyte sequester metal ions. Potentiometric measurements carried out at different ionic strengths (0.1 - 0.7 mol L-1, Na+ medium) allowed us together dependence protonation constants on strength calculate constant infinite dilution. formation species between was investigated potentiometrically (using H+, Cu2+ Cd2+ Ion Selective...
