Energy band gap tuning of Ba-Ca hexagonal ferrite by Dy3+ ion substitution (0 ≤ x ≤ 0.2) to improve spectral, structural, dielectric and photocatalytic properties

In the present study, Dy3+ substituted M-type Ba0.5Ca0.5DyxFe12-xO19 (0.00 ≤ x ≤ 0.20) hexagonal ferrites were synthesized using sol-gel auto-combustion method with lemon extract as a fuel. The single hexaferrite phase with space group P63/mmc is revealed by the X-ray powder diffraction (XRD) patterns. The Field emission scanning electron microscopy (FESEM) exhibits the agglomeration of nanoplates with vacancies at some places. Energy dispersive X-ray photoelectron spectroscopy (EDAX) mapping confirmed the presence of Ba, Ca, Fe, O, and Dy in the hexaferrite. Fourier Transform Infrared (FTIR) spectroscopy exhibits two characteristic bands at 579 and 429 cm−1 corresponding to tetrahedral and octahedral metal ions-oxygen stretching, revealing the occurrence of the ferrite phase. The optical energy band gap calculated using the Tauc plots was found to increase with the increase in dysprosium substitution to fall within the range of 2.8–3.5 eV. The Raman spectra confirmed the Raman vibration modes and M-type structures of hexagonal ferrites (HFs). The dielectric constant values drop rapidly with increasing frequency up to a few KHz and then gradually for the further higher frequencies. The occurrence of Ba and Ca with 2+, while Dy, and Fe with 3+ oxidation states is confirmed using X-ray photoelectron spectroscopy (XPS). The HFs exhibit remarkable efficiency by degrading the Reactive Brown dye to 99.3 % in just 15 min, equivalent to a high degradation reaction rate constant (k) value of up to 0.0396 min−1. Consequently, the catalyst shows promising potential for environmental remediation.

New Pipeline for Analysing Fruit Proteolytic Products Used as Digestive Health Nutraceuticals

Proteolytic products are extensively used in the nutraceutical sector to improve protein digestion and muscle quality in target populations (e.g., athletes or elderly). These products are processed using techniques that often lead to low purity but competitive pricing. Despite their widespread use and well-established production methods, the industry lacks standardized analytical methods for assessing these products and detecting potential fraud. This study proposes a comprehensive and harmonized pipeline for their analysis, which includes quantifying total soluble protein and proteolytic activity, as well as the determination of product stability and protein profile using SDS-PAGE and proteomic techniques. Despite the fact that protease extracts from pineapple had the highest protein content, most of the bromelain remained inactive, unlike in kiwi and papaya. SDS-PAGE revealed partial protein degradation of pineapple extracts, whereas kiwi extracts reflected a lower purification level but a higher protein integrity. The application of proteomic approaches strengthened the identification and origin tracing of the proteases. This study contributes to the development of a robust framework for analyzing proteolytic extracts, spanning from soluble protein quantification to protein profiling and activity determination. It may also ensure reliable supplier selection, high-quality manufacturing practices, and the implementation of optimal storage and formulation strategies in the nutraceutical industry.

In this study, the effect of the antioxidant extract from lemon by-products (Citrus × Limon L.) integrated into an edible alginate-based coating was evaluated to preserve the storage quality of ready-to-eat Clementine (Citrus × Clementina) fruits. The effects of different coatings (1.5% of alginate and 1.5% of alginate + 2–4% of lemon by-product extract) were assessed by the physical, chemical, microbiological, sensorial, and structural analyses of ready-to-eat Clementine fruits stored for 21 d at 4 °C. Ready-to-eat Clementine fruits coated with alginate and extract from lemon by-products showed greater levels of polyphenols, flavonoids, antioxidant activity, and organic acids. A microbiological analysis revealed the dose-dependent effect of the extract to contrast the growth of mesophilic bacteria, yeast, and molds during storage. A sensory analysis confirmed that the enriched coating improved the visual, structural, and olfactory parameters until the end of storage. The evidence in this study proves that an antioxidant extract from lemon by-products is a great sustainable treatment to preserve ready-to-eat fruits.

Sonochemical Facile Synthesis of Bismuth Oxide Nanoparticles Using Citrus Lemon Extract and Its Catalytic Activity on Azo Dye Degradation

The synthesis of bismuth oxide nanoparticles through sono-cavitation using citrus lemon extract as a simple, eco-friendly and cost-efficient method was evaluated. The aqueous extract of citrus lemon acted as a bio-reducing and capping/stabilizing agent in the single-step biosynthesis of bismuth oxide nanoparticles. Different instrumental techniques have been used to characterize the biosynthesized bismuth oxide nanoparticles, including UV–vis spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray powder diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, X-ray photoelectron spectroscopy and energy-dispersive X-ray spectroscopy (EDS). UV–vis spectroscopy revealed the formation of stable bismuth oxide nanoparticles at λmax of 400 nm with a surface plasmon resonance (SPR) band. TEM revealed that the biosynthesized bismuth oxide nanoparticles were rod shaped with a particle size of 26 nm. A potential mechanism for the formation of bismuth oxide nanoparticles with the influence of sono-cavitation has been suggested based on the observed findings. These catalytic capabilities of the bio-synthesized bismuth oxide nanoparticles were then evaluated by degradation of toxic azo dyes under different laboratory conditions. The azo dye Congo red (CR) was effectively degraded to 86% within 30 min under optimum experimental conditions using 0.12 g/mL catalyst. Thus, the phytochemical citrus lemon offers a cheap and eco-friendly solution for the synthesis of catalytic nanoparticles to degrade highly toxic organic compounds such as azo dyes.Graphical

Acrylamide detection and reduction in meat products using organic acids, fruit extracts, and probiotics

Grilled foods are an important source of acrylamide, which has neurotoxic, genotoxic, and carcinogenic properties. The current study aims to evaluate the level of acrylamide in beef, chicken, and fish products, especially those requiring high cooking temperatures, using High Performance Liquid Chromatography (HPLC). Reduction of acrylamide by organic acids i.e., (citric acid, malic acid, tartaric acid, and lactic acid) and fruit extracts of lemon, apple, and grape has also been investigated. The results revealed that the highest mean acrylamide concentration was found in chicken products (grilled chicken) which recorded 8.32 μg/100 g, followed by beef products (beef grilled) with a concentration of 7.91 μg/100 g, and fish products (pan-fried fish burgers) which recorded 6.77 μg/100 g). Furthermore, the mixture of organic acid has the highest effect on reducing the level of acrylamide in a chemical model system. Moreover, the fruit extract mixture was more effective in reducing the percentage of acrylamide in the grilled chicken than organic acids mixture. Finally, the addition of fruit extract improved the sensory properties of grilled chickens. In sum, this study offers novel and promising natural strategies to decrease acrylamide in meat products toward further future application in meat industry to deliver safe food to consumers.

Phytochemical characterization and quality evaluation of stirred goat milk yoghurt with added fruit and vegetable puree during storage

PurposeGoat milk yoghurt differs from cow milk yoghurt in that it has a different casein composition and content, which presents several technical challenges, including consistency with an appropriate flavor.Design/methodology/approachIn this study, the antioxidant potential and phytochemical profiling of the fruits (pineapple and papaya) and vegetable (carrot) extracts was evaluated and the effect of their purees on the quality and stability of stirred goat milk yoghurt (GMY) were investigated. The qualities of stirred GMY with carrot (CrY), pineapple (PaY) and papaya (PpY) purees were assessed against the product without puree (CY).FindingsThe carrot puree had the highest moisture, ash contents and pH value. The carrot extract had the highest DPPH radical scavenging activity, while the pineapple extract had the highest total phenolic value (1.59 µg GAE/g) and flavonoids content (0.203 µg CE/g). The scanning of all the puree extracts in GC-MS indicated that 5-hydroxymethylfurfural was a major component. The phytochemical quantification of the extracts through multiple reaction monitoring (MRM) against 16 compounds showed the presence of sinapic acid, cinnamic acid, pthalic acid, ferulic acid, 4-OH-benzoic acid, 3-OH-benzoic acid, p-coumaric acid, caffeic acid and vanillic acid in different quantities. The addition of purees and storage period had a significant (p < 0.05) effect on the moisture, pH, titratable acidity, syneresis, viscosity, color values and sensory properties of the products. In all the samples after 15 days of storage, Streptococcus thermophilus and Lactobacillus bulgaricus counts remained above the recommended level of 106CFU/g. Stirred GMY sample produced with pineapple puree showed a higher syneresis and viscosity, but the CrY sample demonstrated the highest antioxidant activity. The developed formulations remained stable with minimum changes in quality and sensory attribute during refrigerated storage for 10 days.Originality/valueThis study suggests that addition of fruit and vegetable improve the viscosity and sensory perception of the product with minimal use of synthetic flavor and preservatives.

Applying Giloy Stems Dye to Silk and Lyocell Fabrics to Improve Their Antimicrobial and Fastness Properties Using Bio-Mordant

The investigation of novel strategies to combat harmful bacteria is warranted given the serious threat that antimicrobial resistance poses to world health. Out of all of these, treating textile materials with antimicrobial compounds has attracted a lot of attention due to its potential to stop the spread of infectious diseases. The goal of this study was to evaluate how silk and lyocell materials' inherent antibacterial qualities might be improved by giloy dyeing and lemon mordanting. The goal of mordanting was to improve dye adhesion by using only natural ingredients such as citrus lemon extract. Using dye from Azadirachta indica, which was made by aqueous boiling, Lyocell and Silk materials were dyed under various circumstances. Following Giloy dyeing and Lemon mordanting, the antibacterial efficiency significantly improved, notably against common infections like Klebsiella pneumoniae and Staphylococcus aureus, according to the results. Furthermore, the study assessed washing and perspiration fastness capabilities, which yielded positive results and confirmed the method's feasibility. This method has the potential to considerably improve infection control measures in textiles, particularly in fields focused on public health and cleanliness. Given the serious issue of antimicrobial resistance, adopting new textile treatments like this can help to build effective and sustainable solutions. Future studies can investigate further uses and adjustments, assuring its adaptability and wider adoption across many environments.

Evaluation and comparison of the efficiency of ultrasonically activated intracanal irrigants grapeseed and pineapple extract in removing smear layer from the apical third of the root canal: An in vitro SEM analysis

ABSTRACT Aim: This study aims to evaluate and compare the efficiency of grapeseed and pineapple extract in removing smear layer from the apical third of root canal, with and without ultrasonic activation. Methods: Eighty single-rooted permanent teeth were divided into two main groups: Group I: conventional syringe irrigation and Group II: ultrasonic activation. Each group was subdivided into two experimental groups, i.e. grapeseed and pineapple extract and one control group, i.e., 17% ethylenediaminetetraacetic acid (EDTA). For each subgroup, instrumentation was done using ProTaper Gold up to size F3 and irrigated with 5 mL of the respective irrigant, followed by a final rinse of 2.5 mL of 5.25% NaOCl. For Group II, the respective irrigant was ultrasonically activated for 1 min, followed by a final rinse of 2.5 mL of 5.25% NaOCl. Smear layer evaluation was done with scanning electron microscope, and data were statistically analyzed. Results: In Group I, both pineapple and grapeseed extracts were more effective than 17% EDTA in removing smear layer from the apical root canal. However, in Group II, 17% EDTA showed highest efficacy in smear layer removal, followed by pineapple and grapeseed extracts (P &lt; 0.05). Conclusion: Natural extracts such as pineapple and grapeseed seeds extracts exhibit potential for smear layer removal in the apical third, without the disadvantage of dentinal erosion from synthetic smear layer removing agents.

Phytochemicals in vital tooth bleaching: Spectrophotometric evaluation of efficacy with papaya, pineapple, or kiwi extracts and 30% hydrogen peroxide.

Dental bleaching, a common cosmetic treatment, typically uses hydrogen peroxide (H2O2). Yet, the search for natural options has prompted an investigation into fruit extract efficacies such as papain, bromelain, and actinidin for tooth whitening. The aim of this study was to evaluate the efficacy of 30% hydrogen peroxide and fruit extracts (papaya, pineapple, and kiwi) on human enamel using a spectrophotometer at different time intervals. Eighty maxillary anterior teeth were stained with tea solution and evaluated for baseline color. They were then divided into four groups: hydrogen peroxide alone and hydrogen peroxide combined with papaya, pineapple, or kiwi extracts. Each group was further divided based on bleaching duration: 10 or 20 min. The color value of the bleached teeth was measured using a reflectance spectrophotometer. In order to analyze the data, one-way ANOVA, post hoc Tukey, and paired t-tests were used. The significance level was established at α =0.05. Combining hydrogen peroxide with pineapple extract showed the highest efficacy, followed by papaya and kiwi extracts. Hydrogen peroxide alone also demonstrated significant bleaching efficacy, albeit lower than the combinations with fruit extracts. Combining hydrogen peroxide with pineapple and papaya extracts notably improves dental bleaching efficacy, as shown by reduced color difference (ΔE) values. This underscores the potential of natural enzymes in tooth whitening.

Antimicrobial Potential of Pomegranate and Lemon Extracts Alone or in Combination with Antibiotics against Pathogens.

Amidst the growing concern of antimicrobial resistance as a significant health challenge, research has emerged, focusing on elucidating the antimicrobial potential of polyphenol-rich extracts to reduce reliance on antibiotics. Previous studies explored the antifungal effects of extracts as potential alternatives to conventional therapeutic strategies. We aimed to assess the antibacterial and antifungal effects of standardised pomegranate extract (PE) and lemon extract (LE) using a range of Gram-negative and Gram-positive bacteria and two yeast species. Additionally, we assessed the antimicrobial activities of common antibiotics (Ciprofloxacin, Imipenem, Gentamicin, and Ceftazidime), either alone or in combination with extracts, against Staphylococcus aureus and Escherichia coli. PE displayed substantial antibacterial (primarily bactericidal) and antifungal effects against most pathogens, while LE exhibited antibacterial (mostly bacteriostatic) and antifungal properties to a lesser extent. When compared with antibiotics, PE showed a greater zone of inhibition (ZOI) than Ciprofloxacin and Ceftazidime (p < 0.01) and comparable ZOI to Gentamicin (p = 0.4) against Staphylococcus aureus. However, combinations of either PE or LE with antibiotics exhibited either neutral or antagonistic effects on antibiotic activity against Staphylococcus aureus and Escherichia coli. These findings contribute to the existing evidence regarding the antimicrobial effects of PE and LE. They add to the body of research suggesting that polyphenols exert both antagonistic and synergistic effects in antimicrobial activity. This highlights the importance of identifying optimal polyphenol concentrations that can enhance antibiotic activity and reduce antibiotic resistance. Further in vivo studies, starting with animal trials and progressing to human trials, may potentially lead to recommendation of these extracts for therapeutic use.

Protein Concentration, Anthelmintic Activity, and Microbial Contamination of the Laboratory-Produced Chitosan-Encapsulated Bromelain Batches

Bromelain has been shown to have potential as an anthelmintic for controlling livestock nematodes, such as Haemonchus (H.) contortus. The present study aimed to evaluate the in vitro quality of the laboratory-produced nanoencapsulated bromelain (NEB) and its activity against H. contortus. The acid-base extraction method was employed to extract four different batches of bromelain from the peels of fully ripened pineapples. It was encapsulated in chitosan to form the nano-encapsulated bromelain complex. Standard biochemical methods were employed to determine the bromelain concentration, protein concentration, in vitro anthelmintic activity against various stages of H. contortus (egg, larva, adult), and bacteria contamination for the four NEB batches. The mean concentration of extracted bromelain was 4.3 mg/ml in all four batches. There were no variations in the protein concentrations between the batches of NEB, which ranged from 1,090 mg/ml to 1.205 mg/ml. Although there were no significant differences in different batches, a variation in NEB inhibitory concentration (IC50) was observed according to the different parasitic stages. The highest activity was for adult worms (LC50 =0.2454 ± 0.05 mg/ml), followed by the eggs (IC50 = 0.3 ± 0.07 mg/ml), and the larval stage (IC50 =0.9 ± 0.45 mg/ml). Despite the identification of certain bacterial species in the raw pineapple extract, the final product of all four batches of NEB remained free from any bacterial contamination. The current study indicated that NEB's concentration, protein concentrations, and anthelmintic activity did not vary significantly across the different batches of NEB. Additionally, the encapsulation process ensured that the final product was free of bacterial contamination and thus safe for use in animals.
