Human skin acts as a physical barrier; however, sometimes the skin gets infected by fungi, which becomes more severe if the infection occurs on the third layer of the skin. Azole derivative-based antifungal creams, liquids, or sprays are available to treat fungal infections; however, these formulations show various side effects on the application site. Over the past few years, herbal extracts and various essential oils have shown effective antifungal activity. Additionally, autoxidation and epimerization are significant problems with the direct use of herbal extracts. Hence, to overcome these obstacles, polysaccharide-based nanohydrogels embedded with natural plant extracts and oils have become the primary choice of pharmaceutical scientists. These gels protect plant-based bioactive compounds and are effective delivery agents because they release multiple bioactive compounds in the targeted area. Nanohydrogels can be applied to infected areas, and due to their contagious nature and penetration power, they get directly absorbed through the skin, quickly reaching the skin’s third layer and effectively reducing the fungal infection. In this review, we explain various skin fungal infections, possible treatments, and the effective utilization of plant extract and oil-embedded polysaccharide-based nanohydrogels.

This paper presents a novel approach for the recovery of lead from waste cathode-ray tube (CRT) glass by applying a combined chemical-electrochemical process which allows the simultaneous recovery of Pb from waste CRT glass and electrochemical regeneration of the leaching agent. The optimal operating conditions were identified based on the influence of leaching agent concentration, recirculation flow rate and current density on the main technical performance indicators. The experimental results demonstrate that the process is the most efficient at 0.6 M acetic acid concentration, flow rate of 45 mL/min and current density of 4 mA/cm2. The mass balance data corresponding to the recycling of 10 kg/h waste CRT glass in the identified optimal operating conditions was used for the environmental assessment of the process. The General Effect Indices (GEIs), obtained through the Biwer Heinzle method for the input and output streams of the process, indicate that the developed recovery process not only achieve a complete recovery of lead but it is eco-friendly as well.

The efficiency of some films prepared from heat-denatured whey protein isolate solutions on the quality and shelf-life of brook trout samples during storage at 4 °C was studied in this research (WPIf-a film based on whey protein isolate and WPIf+2.5%TEO-a film based on whey protein isolate incorporated with 2.5% tarragon essential oil). The control and covered fish samples were periodically assessed (at 3 days) over 15 days of storage for the physicochemical (pH; EC, electrical conductivity; TVB-N, total volatile basic nitrogen; TBARS, thiobarbituric acid reactive substances; color), microbiological (TVC, total viable count; PTC, psychrotrophic count; LAB, lactic acid bacteria; H2S-producing bacteria), and sensory properties (color discoloration; odor; overall acceptability). The WPIf+2.5%TEO has proven enhanced quality preservation effects compared to WPIf by showing lower values for physicochemical parameters, lower microbial loads, and higher sensory scores in the fish sample. All these effects have led to an extension of the sample’s shelf-life. In conclusion, the tarragon essential oil has conferred antioxidant and antimicrobial properties to the film. Thus, the WPIf+2.5%TEO could be a promising material for the packaging of fresh brook trout during refrigerated storage.

One of the biggest challenges in managing the food sector during a pandemic crisis is sustaining a robust food security system and adopting the right strategies in correlating the consumers’ needs and requirements with those of food safety, the producers, the distribution chain, the economic environment, and waste management. The restrictions on people’s global movement, commodities, and services and the measures taken to reduce the spread of COVID-19 have disrupted food environments around the world and forced us to collectively redesign and optimize our systems using existing resources from a more sustainable perspective. This paper offers an overview of the implications of COVID-19 for the food supply chain and discusses several potential strategies for tackling short- and long-term adverse effects resulting from the pandemic.

Five selected wild edible mushrooms from Romania (Agaricus bisporus, Pleurotus ostreatus, Cantharellus cibarius, Boletus edulis, and Lactarius piperatus) were investigated for their antioxidant potential using an ABTS spectrophotometric assay. Among the selected mushrooms, B. edulis displayed the highest radical scavenging activity and the greatest phenolic content, measured by the Folin–Ciocalteu reagent method. The total flavonoids were quantified using the aluminum chloride colorimetric method, with the extract of B. edulis being the richest. L. piperatus and B. edulis mushrooms exhibited the strongest antibacterial activity against S. aureus and E. coli. The content of trace elements was determined using an atomic absorption spectrometer, and it was found that K and Mg were the main metals present in all the selected mushroom species. The obtained results suggest that the studied wild edible mushrooms are natural functional matrices, and may have potential to be used as natural antioxidants if they are introduced into the daily diet.

The effects of heat treatment and the addition of tarragon essential oil on physical and mechanical properties of films prepared with 5% whey protein isolate (WPI) and 5% glycerol were investigated in this study. Heat treatment of the film-forming solution caused increases in thickness, moisture content, swelling degree, water vapor permeability (WVP), b*-value, ΔE*-value, transmittance values in the 200–300-nm region, transparency, and puncture resistance of the film, but decreases in water solubility, L*-value, a*-value, transmittance values in the 350–800-nm region, and puncture deformation. When incorporated with tarragon essential oil, heat-treated films have the potential to be used as antimicrobial food packaging. The addition of tarragon essential oil in film-forming solution caused increases in moisture content, solubility in water, WVP, a*-value, b*-value, ΔE*-value, and transparency of the film; decreases in transmittance values in the range of 600–800 nm; and variations in swelling degree, L*-value, transmittance values in the range of 300–550 nm, puncture resistance, and puncture deformation. Nevertheless, different tendencies were noticed in UNT (untreated) and HT (heat-treated) films with regards to transparency, light transmittance, puncture resistance, and puncture deformation. Based on these findings, HT films show improved physical and mechanical properties and, therefore, are more suitable for food-packaging applications.

The goal of the research was to assess the inhibitory effects of hop extracts, iso-α and β acids, against Pediococcus pentosaceus bacteria, during a short incubation period, both in liquid selective media (high pH values) and beer wort fermentation (low pH values) and testing if the identified iso-α acid stress changes the activity of S. cerevisiae boulardii yeast and ethanol production. Flow cytometry analysis was used for bacterial and yeast cell viability. In relation to the antibacterial activity of β-acids, a lower viability of Pediococcus pentosaceus cells was observed after a short incubation period in selective media, under iso-α acid stress. In beer wort, for a mixed culture with P. pentosaceus bacteria and S. cerevisiae boulardii yeast, under iso-α acid stress conditions at pH 4.0-5.0, Pediococcus pentosaceus exhibited lower cell viability (20.7%) than in selective media (61.4%). Regarding iso-α hop acid on S. cerevisiae boulardii yeast, the results showed that iso-α does not change the S. cerevisiae activity but prevents the culture from being contaminated by Pediococcus pentosaceus. The results highlighted reliable inhibitory effects of iso-α and β-acids against P. pentosaceus, both at pH 6.0-7.0 and pH 4.0-5.0, which open the possibility of hops being used as a supplement to prevent beverage contamination with spoilage microorganisms. ********* In press - Online First.

This study aimed to determine the chemical composition, fatty acids, volatile profile and phenolic compounds profiles from five wild edible mushrooms (Agaricus bisporus, Pleurotus ostreatus, Cantharellus cibarius, Boletus edulis, Lactarius piperatus) from Romania. The results indicated that the dried fruiting bodies of selected mushrooms were rich in proteins (36.24 g/100 g dw-Boletus edulis) and carbohydrates (62.45 g/100 g dw-Lactarius piperatus). 4-Hydroxybenzoic acid and cinnamic acid, were the main phenolic compound present in all selected species. Additionally, the fatty acid pattern included polyunsaturated acids in more than 60% of all fatty acids followed by monounsaturated fatty acids (30%). For the studied mushroom samples, the main volatile compounds identified by the gas chromatography-mass spectrometry were hexanal, benzaldehyde and dodecanoic acid. According to the obtained results, the fruiting bodies of selected Romanian mushrooms are a rich source of bioactive molecules indicating that they may be further exploited as functional ingredients in the composition of innovative food products.

The current study aimed the selective recovery of tin and lead from waste Sn-Pb alloy obtained as a secondary stream in the recovery process of copper from waste printed circuit boards. The recovery of the two metals was achieved through selective direct anodic dissolution of the waste Sn-Pb alloy samples in H2SO4 solutions coupled with the simultaneous electrowinning of a tin rich cathodic deposit. The optimal operating conditions were identified based on the influence of current density, H2SO4 concentration and electrolyte flow rate on the main technical performance indicators. The most favorable operating conditions for the electrochemical process were obtained at 0.5 M H2SO4 concentrations, 60 A/m2 current density and at a flow rate of 45 mL/min. Based on the experimental results the process was scaled-up, modeled and simulated using process flow modeling software CHEMCAD. The mass balance data corresponding to the recycling of 100 kg/h waste solder in the identified optimal operating conditions was used for the environmental assessment of the process. The General Effect Indices, for the input and output streams of the process, obtained through the Biwer-Heinzle method indicate that the developed recovery process it is not only efficient but environmental friendly as well.

This study is focused on the comparison and classification of parsley, lovage, basil, and thyme essential oils (EOs) based on their chemical composition, total phenolic content, antioxidant and antibacterial activities by using appropriate chemometric methods: Principal component analysis (PCA) and hierarchical cluster analysis (HCA). The results showed that parsley, lovage, and thyme EOs are rich in monoterpene hydrocarbons, but basil EO is rich in oxygenated monoterpenes and phenylpropanoids, and that both PCA and HCA separated essential oils into two main groups of which one contains two sub-groups. β-Phellandrene was the major component identified in parsley and lovage EOs, estragole was the major component in basil EO, and p-cymene was the major component in thyme EO. Thyme EO showed the highest level of total phenolics, the highest antioxidant capacity, and exhibited the stronger antibacterial activity, results that were emphasized by both chemometric methods used. Among tested essential oils, the one of parsley was distinguished by a low total TPC, weak antioxidant activity, and weak antibacterial activity against S. enteritidis (ATCC 13076); lovage EO by low TPC, weak antioxidant activity, but moderate antibacterial activity; and basil EO by low TPC, moderate antioxidant activity, and weak antibacterial activity against L. monocytogenes (ATCC 19114).

Antioxidants are substances that protect cells from the induced oxidative stress damage caused by unstable molecules known as free radicals that. Antioxidants neutralize free radicals as a natural by-product of normal cell processes. In the present study,were evaluated the phenolic and flavonoids contents as well as the antioxidant capacity of seeds from the Lamiaceae and Apiaceae family: fennel (Foeniculum vulgare), dill (Anethum graveolens) and rosemary (Rosmarinus officinalis) . (Sreemoyee Ch. et. al., 2012 ) The main objective of the study was the comparative assessment of the phenolic and flavonoid compounds from dill, rosemary and fennel methanolic extracts correlated with their antioxidant activity. Both total phenolic content and flavonoids content of the seeds samples were measured spectrophotometrically using the Folin-Ciocalteu assay and a chromogenic system of NaNO2–Al(NO3)3–NaOH, respectively.. Antioxidant capacity was determined by 2,2-DPPH method. Results strongly showed that Rosmarinus officinalis extract has the most effective antioxidant capacity in scavenging DPPH radicals, while Foeniculum vulgare and Anethum graveolens were less active. The total phenolic content was within 773,14 and 3367,24mg GAE/ 100g while the concentration in flavonoids was between 231,84 and 1325,53 QEg/100g dry seeds.
