Summary: Commercial Tara gum from three sources was purified by precipitation with isopmpanol and evaluated on the structural, physicochemical and rheological properties. The monosaccharide composition of Tara gum galactomannans showed strong influence of their origin, with intrinsic viscosity being influenced by origin and temperature. The rheological behavior at diluted concentrations resulted in shear thickening fluid.

Summary: By mixing fish gelatin, Tara gum, and glycerol in different ratios and subjecting Tara gum to ball milling treatment, films with different morphologies can be obtained. The amount of glycerol and the type of Tara gum used strongly influence the morphology and density of the films, which in turn determine the thermal and mechanical behaviors. Improvements in thermal stability and mechanical properties can be achieved by using milled Tara gum or increasing glycerol content, up to 20 wt%. Exceeding this percentage of glycerol is detrimental to film quality and reduces thermal and mechanical performances.

Summary: Circular Gleditsia sinensis gum, Gleditsia microphylla gum, and tara gum are galactomannans with similar mannose/galactose molar ratios. The hydrophobic interactions and critical aggregation concentrations of the galactomannans were compared using a fluorescence probe technique. The results showed that increasing galactomannan concentration led to the formation of hydrophobic domains, while temperature and urea concentration affected the destruction and formation of these domains, respectively.

Summary: This study focused on developing and characterizing edible films made from Persian gum with glycerol and emulsified oil droplets. The addition of glycerol and oil droplets improved the mechanical properties of the films while reducing water solubility and water vapor permeability. The optimal concentration was found to be 0.9% glycerol and 1% emulsified oil droplets, making the films suitable for food packaging.

Summary: Galactomannans are commonly extracted polysaccharides from various leguminous seeds. Enzymatic and ultrasound depolymerisation can decrease their viscosity and molecular weight, resulting in the generation of different polysaccharide units. The study shows that the enzymatic hydrolysates exhibit reactivity towards non-enzymatic browning, indicating potential applications in various industries.

Summary: Bioactive edible packaging films have gained increasing attention as a result of concerns over the excessive use of petroleum-based synthetic packaging materials for food. Among various materials, chitosan stands out as the most suitable polysaccharide due to its biodegradability and biocompatibility. However, its poor barrier and mechanical properties limit its application as a food packaging material. Numerous studies have been conducted to enhance the characteristics of chitosan films by modifying preparation techniques and incorporating other natural substances to create composite films. This paper provides an overview of these modifications and their impact on the physicochemical and biological properties of chitosan-composite edible films.

Summary: Similar to other water-soluble polymer films, pure soluble soybean polysaccharide (SSPS) films are rigid and brittle, limiting their practical applications in food packaging. This study investigated the effects of three commonly used polyol plasticizers on the properties of SSPS films. The addition of plasticizers significantly improved the ductility and water content of the films. PEG400-plasticized SSPS films showed the highest transparency and thermal stability, while sorbitol-plasticized films had better tensile strength and water vapor barrier properties. Glycerol-plasticized films had the highest elongation at break, moisture content, and water solubility.

Summary: The main purpose of this paper is to synthesize a new green and environmentally friendly emulsion for water erosion resistance. A non-toxic polymer was prepared by grafting AA and MMA onto the long chains of TG to synthesize a copolymer emulsion (TG-g-P(AA-co-MMA)). The polymer's structure, thermal stability, morphology, and wettability were characterized, and the key synthesis conditions were optimized for emulsion performance (viscosity). The study found that TG-g-P(AA-co-MMA) emulsions have good potential for soil remediation applications, with improved thermal stability, viscosity, erosion resistance, and compressive strength.

Summary: The surface-modified nanoparticles of Eugenol (EU) and carvacrol (CAR), known as EU-CF and CAR-CF NPs, respectively, displayed bactericidal effects on E. coli and bacteriostatic effects on Staphylococcus aureus. Fourier transform infrared spectroscopy (FTIR) analysis revealed significant changes in bacterial carbohydrates, lipids, and DNA. The CF conjugated NPs showed better membrane damage and DNA disintegration in Gram-negative E. coli than in Gram-positive S. aureus. Furthermore, the presence of EU-CF and CAR-CF NPs inhibited the growth of E. coli in orange juice without affecting the flavor compounds.

Summary: In this study, the impact of curcumin-nanoemulsion-loaded corn starch gels with different amylose contents on the release and bioaccessibility of curcumin during in vitro gastrointestinal digestion was investigated. It was found that the addition of curcumin nanoemulsion significantly increased the storage modulus of waxy and normal corn starch gels, but decreased in high amylose corn starch gels. The disintegration and emptying of the waxy corn starch gel from the stomach was the slowest, while the high amylose and normal corn starch gels showed a higher and faster release of curcumin during intestinal digestion.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
