Summary: This study investigated the effects of high intensity ultrasound (HIU) powers on a soy protein isolate (SPI)-pectin (PC) complex. The results showed that HIU treatment altered the protein structure, leading to improved solubility and dispersibility of the complex. Selecting appropriate HIU treatment power can effectively enhance the functional properties of the SPI-PC complex.

Summary: Ultrasound was used to modify the molecular structure of proteins and polysaccharides, and their interactions were investigated in the peanut protein isolate-high methoxy pectin (PPI-HMP) complexes. Various ultrasound parameters, PPI-HMP mixing ratio, and pH were studied. Results showed an electrostatic interaction between PPI and HMP at pH 2.0-6.0. Ultrasound changed the conformation and hydrogen bonding of PPI. Appropriate ultrasound treatment reduced viscosity and enhanced interactions between PPI and HMP. These findings are important for the food industry's use of PPI-HMP complexes.

Summary: Chemically bonded nonwovens are traditionally made with a latex binder containing plastic polymer and cellulosic fibers. However, they have low biodegradability and cannot be recycled. In this study, a biobased binder (PEC) made from carboxymethyl cellulose and chitosan dissolved in citric acid was combined with pea protein (PP) to create a fully biobased nonwoven with hydrophobic properties. By adjusting the fat content in PP and the protein content in the binder, different degrees of hydrophobicity and mechanical properties were achieved. The cured system showed a stable contact angle of around 120 degrees and significantly improved strength and stiffness compared to binder-free nonwovens in both dry and wet states.

Summary: This article introduces a genetically modified Trichoderma reesei strain RF6201 produced food enzyme pectinesterase and its safety assessment. The food enzyme is considered safe and is intended to be used in five food manufacturing processes. The estimated dietary exposure of the enzyme is up to 0.532 mg TOS/kg bw per day in European populations. Genotoxicity and repeated dose toxicity tests did not raise safety concerns, but two matches were found with pollen allergens, indicating a potential risk of allergic reactions in individuals sensitised to pollen allergens.

Summary: The effect of pH on the states of peanut protein isolate (PPI) and high methoxyl pectin (HMP) and the breakup model of emulsions under ultrasound were investigated. It was found that PPI-HMP formed a soluble complex at pH 5.0, had no interaction at pH 7.0, and was co-soluble at pH 9.0. The characteristics of the emulsion stabilized by PPI-HMP differed at different pH values. The research provided insights for the development of emulsions using pH-shifted PPI-HMP under ultrasound.

Summary: The study found that the complexation of pea albumin-rich fraction and ovalbumin with pectin of different degrees of esterification and blockiness is influenced by the pH and biopolymer mixing ratio. Turbidimetric analysis and isothermal titration calorimetry revealed that high esterification and blockiness pectin had stronger interactions with pea albumin, while low methoxy pectin showed better interactions with ovalbumin. The thermodynamic parameters of PA-pectin complexes can be controlled by adjusting the structural characteristics of the pectin.

Summary: This work reports on the synthesis and characterization of ZrO2 aerogels prepared by the epoxide-assisted sol-gel method using supercritical drying with CO2. The influence of HNO3 as a catalyst and CTAB surfactant on the properties of the aerogels was investigated. The results showed that the use of CTAB surfactant increased the specific surface area of the aerogel and maintained its 3D network structure. The ZrO2 aerogels exhibited good biocompatibility and high drug loading efficiency, making them potential biomaterials for drug delivery.

Summary: The development of polysaccharide-based films is driven by the problems with plastic materials and the film-forming properties of polysaccharides. In recent years, there has been a surge in research on using green solvents such as ionic liquids (ILs) and deep eutectic solvents (DESs) as alternatives to conventional solvents/plasticizers for preparing polysaccharide-based films. This review summarizes the properties and recovery of ILs and DESs, various green preparation strategies, and the characteristics of polysaccharide-based films with and without ILs and DESs. The advantages of these new solvents include high solubility for polysaccharides and better plasticizing ability compared to traditional plasticizers. They also possess antioxidant and antibacterial properties that are beneficial for applications in active food packaging films.

Summary: In this study, plasticized polyvinyl chloride (PVC) composites were prepared by adding tantalum oxide V (Ta2O5) and/or bismuth oxide III (Bi2O3) nanoparticles (NPs) and further cross-linking them. The resulting materials are lightweight, flexible, and non-toxic, making them suitable as radiation attenuators in the medical field to replace toxic and dense lead. Mechanical tests and density measurements show that the composites have enhanced tenacity and lightness. The SEM images demonstrate the proper dispersion of the nanoparticles (NPs). The X-ray attenuation property of the composites was evaluated, and it was found that when PVC composites were loaded with 50 wt% of a combination of Ta2O5 and Bi2O3 NPs, the mass attenuation coefficients were higher than those of lead. Cell viability tests confirmed the non-toxicity of the composites. Therefore, these investigated materials show promise for the fabrication of medical diagnostic X-ray shielding attachments.
