This study primarily investigated the impact of pH-shifting on the gel properties of Flammulina velutipes polysaccharide (FVP)-porcine myofibrillar protein (MPs) gels, aiming to improve the quality of Flammulina velutipes-pork patties. Our findings revealed that the water holding capacity (81.72 %), oil holding capacity (87.41 %), emulsion activity index (81.05 %), emulsion stability index (52.58 %), and rheological properties of FVP-MPs gels were all enhanced under optimal pH 9 conditions. Alkaline conditions led to a more compact structure, with hydrogen bond interactions and hydrophobic interactions being the primary molecular forces. The physicochemical and sensory properties of pork patties prepared at pH 9 were enhanced, with key odor active substances such as 1-Penten-3-ol, 1-Propanol-M and 2-Ethylbutanal-M contributing to an improved flavor. This study provides comprehensive insights into the gel properties and interaction behavior of FVP-MPs gels under varying pH conditions, highlighting the potential for enhancing meat product quality by incorporating Flammulina velutipes at optimal pH values.

The preparation of new phosphor with outstanding luminescent properties for white light-emitting diodes (WLEDs) is consistently a challenging. Here in the present study, A novel white-emitting chloropatite phosphor Ca(PO)Cl:Eu was synthesized via the pechini sol gel synthesis with citric acid and polyethylene glycol (PEG) acid as a fuel at 850 °C systematically investigating the impact of doping concentration and synthesis temperature on both photoluminescence properties and crystal phase. The structural characteristics and crystalline nature of the prepared sample were investigated by using X-ray diffraction (XRD) patterns and Fourier transform infrared (FT-IR) spectra.

Hydroxyapatite nanoparticles (HANPs) are becoming increasingly crucial in dental implant applications as they are highly compatible with biological systems, actively support biological processes, and closely resemble bone minerals. This review covers the latest progress in how HANPs are made, studied, and used in dentistry. It looks at critical methods for creating HANPs, such as sol-gel, microwave hydrothermal synthesis, and biomimetic approaches, and how they affect the particles' size, structure, and activity.

Chronic wounds caused by microbial infection have emerged as a major challenge on patients and medical health system. Bacterial cellulose (BC) characterized by its excellent biocompatibility and porous network, holds promise for addressing complex wound issues. However, lack of inherent antibacterial activity and cross-linking sites in the molecular network of BC have constrained its efficacy in hydrogel design and treatment of bacterial-infected wounds.

In this study, bio-based composite films with enhanced barrier, mechanical, antioxidant and antimicrobial properties were prepared by incorporating Stropharia rugosoannulata waste (SP)-derived polysaccharides (SPP) and carbon dots (SPCDs) as an active substance into gelatin (GEL) matrix, which were evaluated for their potential application in pork preservation. The effects of varying concentrations of SPCDs on the morphology, microstructure, and overall performance of the films were systematically investigated. The findings demonstrated that the addition of SPCDs to the GEL/SPP matrix significantly improved the mechanical strength, water vapor permeability, and ultraviolet light blocking ability of the composite films.
