Protein networks and starch nanocrystals jointly stabilizing liquid foams via pickering-type coverages and steric hindrance

Tao Wang et al.

Summary: Liquid foams are stabilized by protein networks in association with starch nanocrystals, forming stable foams that can last up to 4 days after high-speed frothing. The joint stabilization mechanisms of the liquid foams involve docking of RP-PP@SNCs at the interface and the formation of three-dimensional networks in the continuous phase.

The adsorption characteristics of 2D fibril and 3D hydrogel aggregates at the O/W interface combining molecular dynamics simulation

Zongyuan Han et al.

Summary: This study investigated the effects of spatial conformation, crystal structure, and microstructures on interfacial adsorption. With increasing pH, the alpha-helix contents and surface hydrophobicity decreased significantly in the emulsified aggregates, while beta-sheet contents increased significantly. The alpha-helix contents and surface hydrophobicity were higher in 2D fibril aggregates compared to 3D hydrogel aggregates, but the beta-sheet results varied with different hydrophobic amino acid sequences. The peak intensity and crystallinity were higher in hydrogel aggregation mode, and the transformation of crystal structure influenced the interfacial microstructure.

Phytochemical Compound Screening to Identify Novel Small Molecules against Dengue Virus: A Docking and Dynamics Study

Mst. Sharmin Sultana Shimu et al.

Summary: This paper presents a computational analysis to discover effective inhibitors for Dengue virus infection using virtual screening and molecular dynamics. Phellodendroside, quercimeritrin, and quercetin-7-O-rutinoside were identified as potential compounds based on their binding free energy. The study also investigated the pharmacological properties of these compounds and found no toxicity.

Effects of the non-covalent interactions between polyphenols and proteins on the formations of the heterocyclic amines in dry heated soybean protein isolate

Yang Chen et al.

Summary: The study revealed that polyphenols, when complexed with soybean proteins, can alter the protein structure and interaction, thereby influencing the formation of heterocyclic amines (HAs). This provides a theoretical basis for understanding the mechanisms behind HA formation in polyphenol-inhibiting protein foods.

Adsorption kinetics of ovalbumin and lysozyme at the air-water interface and foam properties at neutral pH

Haobo Jin et al.

Summary: This study investigated the dynamic adsorption properties of ovalbumin and lysozyme at the air-water interface and the foam properties at neutral pH. A 5:5 ratio of ovalbumin to lysozyme was found to result in the most stable foam structure, with maximum turbidity. The appropriate protein ratio was crucial for the relaxation of the protein complex structure and the mechanical structure of the interfacial composite protein membrane.

Overview of foam system: Natural material-based foam, stabilization, characterization, and applications

Fuchao Zhan et al.

Summary: The research focus on foam materials has recently shifted from inorganic to biological origin materials, especially edible materials, for stabilization purposes. This shift is motivated by the incompatibility of some inorganic materials with food and biomedical applications, as well as their poor sustainability. Recent research has shown that protein, polysaccharide, polyphenol, and their combinations can effectively stabilize liquid foam. This review summarizes the mechanism of foam instability, factors affecting stability, and recent progress in characterization methods. It also highlights the promising trends in basic research and applications, which offer exciting opportunities in the food industry.

Study on the mechanism of non-covalent interaction between rose anthocyanin extracts and whey protein isolate under different pH conditions

Yun Wang et al.

Summary: This study investigated the non-covalent interaction mechanism between rose anthocyanin extract (RAEs) and whey protein isolate (WPI) and compared it with the interaction mechanism between pure anthocyanin (PC) and WPI. The results showed that RAEs and WPI had non-covalent interactions under different pH conditions, with hydrogen bonds and van der Waals forces playing a role. Interestingly, PC and WPI also exhibited non-covalent interactions, with hydrogen bonds and van der Waals forces as the driving forces. Additionally, changes in WPI's secondary structure were observed in both RAEs and PC.

Evaluation of interaction between citrus flavonoid, naringenin, and pepsin using spectroscopic analysis and docking simulation

Elham Raeessi-Babaheydari et al.

Summary: Naringenin affects the structure and activity of pepsin by forming complexes, quenching its intrinsic fluorescence, and altering the protein structure, resulting in reduced enzyme activity. This interaction is mainly driven by hydrophobic forces, leading to changes in protein stability and rigidity.

Summary: The presence of phenolic compounds in rapeseed extracts can significantly influence the interfacial and foaming properties of whey protein, leading to protein aggregation and reduced foam stability. Removing unbound phenols only partially restores the properties, suggesting a strong binding between phenols and proteins.

Adsorption kinetics and dilatational rheological properties of recombinant Pea Albumin-2 at the oil-water interface

Yilun Luo et al.

Summary: The study found that at the oil-water interface, PA-2 can adsorb in the form of aggregates and exhibit a non-monotonic dependence on the dynamic viscoelastic modulus. The addition of 2-ME impacts the experimental results, causing protein aggregates to disaggregate and rearrange at a higher rate on the interface.

Enhancement of foam stability parallel with foamability of the foam stabilized by sodium caseinate-based complex: Octenyl succinate starch acting a dual role

Fuchao Zhan et al.

Summary: The interaction among SC/TA/OSA-Starch and the foam properties was investigated, showing that OSA-Starch can influence the formation of soluble complexes at different pH levels. It was found that OSA-Starch plays a role in promoting foam formation by advancing the diffusion of SC-based complexes to the air/water interface. The shear-thickening properties of the foam stabilized by SC/TA/OSA-Starch contribute to foam stability.

Summary: The study of aqueous foams in preparation of functional solid foam materials using composite stabilizers is of great interest, as it can enhance foamability, foam stability, and properties of the resulting solid foams. Future research on the colloidal properties and foam stabilization mechanisms of surfactant-nanoparticle, polymer-nanoparticle, and surfactant-graphene oxide composites is needed to explore novel applications and improve foam quality.
