In this study, an active films of polyvinyl alcohol (PVA) films, incorporated with sodium nitrite were developed, characterized and applied to pork stored for six days at 25 °C. As for the film characterization by FTIR, no chemical interactions were observed between nitrite and PVA under the studied conditions. The physical properties of the PVA films were not altered by the presence of nitrite. PVA films incorporated with 100 ppm nitrite reduced TBARS values of refrigerated pork from 0.63 µmol MDA/g (control) to 0.49 µmol MDA/g (PVA 01). Color changes were observed in all meat samples packaged with the film. It is concluded that the presence of nitrite does not interfere in the physical properties of the PVA films and that the developed films have an active potential for application in pork in natura.

This study utilized deep eutectic solvents (DES) based on choline chloride/lactic acid (ChCl/LA) to deconstruct coconut fibers. The effects of DES with different temperatures and molar ratios on the yield of lignin, recovery rate of residues, structural changes in lignin and solid residues, and saccharification efficiency were investigated. The results showed that acidic DES treatment effectively deconstructed the coconut fibers, resulting in a high lignin yield of 68.

Purpose: Due to the extensive use of radiation in various fields, such as food safety, sterilizing surgical materials, and medical diagnostics, it is essential to minimize radiation exposure for both patients and healthcare professionals, even at low doses. To meet this requirement, a composite film has been developed using polyvinyl alcohol (PVA) polymer and nitro blue tetrazolium (NBT) dye to measure low radiation doses effectively.
Methods: Various concentrations of NBT dye (ranging from 0.

The potential of advanced energy storage devices lies in using solid biodegradable polymer electrolytes. This study is focused on a solid blend polymer electrolyte (SBPE) film based on chitosan (CS)-poly(vinyl alcohol) (PVA) blend matrix doped with magnesium chloride (MgCl) salt via solution casting. The interaction of MgCl was verified via X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy.

To overcome the barriers often met by traditional ophthalmic formulations, polymeric films can be utilized as an alternative to enhance drug retention duration while managing medication release. In the current investigation, polymeric films made of poly (vinyl) alcohol (PVA) and chitosan (CS) loaded with Moxifloxacin Hydrochloride (M-HCl) and plasticized with Glutaraldehyde were formulated as potential ophthalmic delivery for the treatment of conjunctivitis. The thickness, surface pH, opacity, folding endurance, and % hemolysis were measured, followed by the transparency, microscopy, electrical conductivity, mechanical strength, swelling index, and invitro drug release studies.
