Summary: Gelatin/carrageenan active packaging films incorporated with turmeric essential oil encapsulated in zein nanoparticles were developed. The films were characterized using FTIR, XRD, and SEM. The physical, chemical, and mechanical properties of the films were improved by the application of TEO-containing nanocomposites. ZNP was found to be an excellent carrier of TEO. The nanocomposite film sustainably released TEO, reducing bacterial colonies and improving the shelf life of chicken meat.

Summary: A nanocellulose-based film with excellent antimicrobial and antioxidant properties was developed by incorporating Pickering emulsion stabilized by functionalized particles. The emulsion droplets formed oil core/CNF shell microcapsules in the active CNF films, achieving high inhibition rates against L. monocytogenes and E.coli. The developed active CNF films have great potential for applications in food preservation and active packaging.

Summary: A functional carrageenan/agar-based film was prepared by combining tea tree oil Pickering emulsion (PET) and zinc sulfide nanoparticles (ZnSNP). The incorporation of ZnSNPs improved the mechanical strength, while PET slightly decreased the strength. However, the combined addition of ZnSNP and PET maintained the mechanical strength with slightly improved flexibility, making it suitable for active food packaging applications.

Summary: This study evaluated the effects of adding different concentrations (0%, 1%, 2%, and 3%) of peach gum (PG) to films made from polyethylene oxide (PEO) combined with Litsea cubeba essential oil (LCEO) for future use as active food packaging. The results showed that the film with 2% PG concentration had the best physical and mechanical properties. The addition of PG improved the glass transition temperature and resulted in films with brighter color, lower water vapor permeability, and the lowest water activity. Furthermore, PG films exhibited high antioxidant and antibacterial activity and maintained the quality of wrapped beef during storage.

Summary: A facile method was employed to fabricate tight ultrafiltration membrane for the removal of naturally existed hazard organic substances from surface water and wastewater. By using metal organic framework MOF of cerium (Ce), a new composite membrane was developed to enhance the performance of polyethersulfone (PES) membrane. The study showed that increasing the content of Ce-AnthMOF could significantly enhance the hydrophilicity and permeability performance of the membrane. Testing the membrane for the treatment of whey wastewater showed high removal rates of various pollutants, indicating a promising approach for efficient wastewater treatment.

Summary: Antimicrobial membranes for food packaging were created by grafting hydroxyethyl cellulose (HEC) with a synthesized monomer, 1-butyl-3-vinylimidazolium bromide (BVIm)[Br], and methyl acrylate (MA). The elasticity of the film increased with the content of BVIm[Br], while the stress strength values varied among different samples. The membranes demonstrated the ability to inhibit the spoilage of Karish cheese without affecting the lactic acid and probiotic bacteria.

Summary: This study implemented an integrated method for standardization of propolis using chromatographic, spectroscopic, palynological and biological analyses. Different digitalization algorithms were utilized to evaluate the HPTLC images, and ImageJ (R) and Gel Analyzer (R) showed superior performance. Multivariable pattern recognition models were constructed to discriminate between different types of propolis, and HPTLC-ESI-MS was used for precise identification. Several health-relevant markers were discovered. An independent UV spectroscopic method and palynological analysis were also used for prediction and determination of plant sources. The identification of plant sources is crucial for the standardization of propolis.

Summary: New chitosan derivative nanofibers with antibacterial properties were successfully produced in this study. Two CS Schiff base derivatives (CS-APC and CS-2APC) were prepared by incorporating 4-amino antipyrine moiety in different ratios, and further modified to obtain CS-APCR and CS-2APCR. The chemical structure was confirmed using spectral analyses. Molecular docking evaluation showed that CS-APCR has good fitting in the active sites of three enzymes with docking score values of - 32.76, - 35.43, and - 30.12 kcal/mol, respectively. CS derivative nanofibers were obtained by blending CS-2APC and CS-2APCR with PVP, resulting in decreased fiber diameters compared to pure PVP. The CS derivatives and their nanofibers exhibited antibacterial activities against Staphylococcus aureus and Escherichia coli, with CS-2APCR nanofibers showing stronger activity against E. coli strains than CS-2APC nanofibers.

Summary: Crosslinking affects the mechanical behavior and tissue metabolism of collagen-based tissues. Aging and diabetes alter the crosslinking type and density, thus changing tissue properties. High-connectivity enzymatic crosslinking and advanced-glycation end-products result in uniform deformation under daily activity, while low-connectivity enzymatic crosslinking does not. High-connectivity model displays more sliding, while AGEs induce instability in structures near the binding sites.
