The objective of the present study is developing a new technique for the preservation of natural cheese by the use of an edible biofilm based on sodium alginate in order to evaluate the effect of the essential oils ( L.) incorporated in the film on the oxidation stability, microbial spoilage, physicochemical characteristics and sensory criteria. The cheese samples coated with sodium alginate incorporated by the oils showed moderate stability in terms of oxidative stabilities of proteins and lipids during storage. In addition, poor microbial growth (total aerobic mesophilic flora, yeasts and fecal coliforms) was observed in cheese samples coated with biofilm, also, the growth of and Molds for all types of cheese were completely inhibited. Additionally, it was observed that the biofilm coating reduced the weight loss and hardness of the cheese comparing with the uncoated sample. The results of sensory analysis revealed that uncoated cheese, coated with sodium alginate and sodium alginate composed of oil of were the most preferred by panelists, in comparison with others. Therefore, it was concluded that this technique of coating cheese with edible film activated with essential oils is preferred and favorable by virtue of the effect of oils preserving the cheese without seriously affecting their organoleptic properties.

Objective: The difficulty of establishing slow release at intestinal infection sites, weak antibacterial effects, as well as the limited broad use of florfenicol oral formulations are the main targets of the current study. Novel hydrogels derived from sodium alginate were developed using a complexation form for florfenicol delivery to achieve slow release at the site of intestinal infection and enhance its antibacterial activity against .
Methods: The optimal formulation, physicochemical properties, stability, pH-responsive performance, antibacterial activity, and in vitro biosafety of the florfenicol hydrogels have been studied systematically.

To address the shortcomings of traditional actuators, such as large size, high energy consumption, and slow response, this study developed a conductive and responsive artificial muscle, exploring the operational principles and performance enhancement techniques for artificial muscles made from sodium alginate and graphene oxide. Initially, the research outlined a preparation methodology using sodium alginate, graphene oxide, and nanonickel as primary materials. Subsequent adjustments in the nanonickel content optimized critical performance metrics, including output force, lifespan, and deflection displacement.

This work analyzes the production of a hydrogel composed of mucilage from the cactus (OFI) and sodium alginate. In obtaining the new material, green synthesis was used, free of chemical compounds, and applied in the treatment of textile effluent for the adsorption of methylene blue (MB). The hydrogel was characterized by FT-IR, XRD, SEM, and zeta potential.

Soybean protein isolate (SPI) exhibits limited functional properties in processing applications due to environmental stressors such as pH, salt ion, and temperature. The present study was devoted to exploring the non-covalent assembly of SPI with chitosan (CS), glucan (GL) and sodium alginate (SA) under different pH conditions. At a fixed mixing ratio (1:1), the phase behavior, protein solubility, and surface hydrophobicity (H) of the resulting protein-polysaccharide complexes (PPCs) exhibited great differences due to the diversity of polysaccharide charge density and structure.
