Summary: All-aqueous microdroplets produced by liquid-liquid phase separation have been used as promising models of artificial cells and offer new methods for solvent-free encapsulation of fragile solutes. In this study, stable and impermeable water-in-water emulsions were constructed by the interfacial self-assembly of mixed sodium oleate/1-decanol bilayers on dextran-rich droplets. The lipid-based membrane was shown to be impermeable to oligonucleotides, proteins, and a low molecular weight dye.

Summary: The HIPE template method, using amphiphilic gelatin (GE) as the sole emulsion stabilizer, was used to prepare a stable GE-HIPE membrane and its zeolitic imidazolate framework-67 (ZIF-67) hybrid composite membrane. The ZIF-67/GE-HIPE composite membrane exhibited good lipophilicity and showed promising emulsion separation properties and organic pollutant adsorption removal ability. This work provides a strategy for the preparation of GE-based hydrophobic modified membrane and demonstrates a typical treatment of adsorption-separation of lipophilic substances.

Summary: This study investigates the effect of the starch amylose/amylopectin ratio on the gel-related properties of the gelatin/starch system using oscillatory shear methods. It is found that the higher self-aggregation and selfentanglement ability of amylose decreases the miscibility of gelatin and starch, resulting in increased viscosity and reduced sol-gel transition temperature. The gelatin/amylopectin-rich system exhibits higher gel hardness and wider linear viscoelastic region due to a more intact and uniform network structure. On the other hand, the gelatin/amylose-rich system shows enhanced resistance to deformation and improved restructuring capacity under different shear forces. These findings provide comprehensive insights into the gel-related properties of the gelatin/starch system and are valuable for the design of gelatin/starch systems with improved gel-related features.

Summary: This study reports an aqueous two-phase system (ATPS) formed in a single-component aqueous solution of alpha-ketooctanoic acid (KOCOOH), with the formation originating from the coexistence of micelles and vesicles. The KOCOOH concentration-driven stepwise aggregation leads to the formation of different structures in the system, showing a constantly changing ionization state of KOCOOH playing a crucial role in phase and aggregate structure transition.

Summary: Recent studies have shown that low salinity waterflooding can improve enhanced oil recovery (EOR), yet it also leads to the formation of unwanted water-in-oil emulsions. This study aims to investigate the impact of water chemistry, specifically ionic strength and ion types, on the stability of natural water-in-oil emulsions. The results indicate that higher ionic strength in the aqueous phase leads to lower emulsion stability, which can be explained by the salting-out mechanism. Furthermore, the presence of certain divalent cations improves emulsion stability, while a sulfate-rich brine results in less stable emulsions.

Summary: Fabrication of bead-free nanofibers from pure casein is challenging due to its self-aggregation tendency. In this study, the influence of pH, ethanol content, ionic environment, and casein concentration on the solubility and solution characteristics of casein-based spinning dopes was analyzed. The addition of tetrasodium pyrophosphate (TSPP) reduced bead defects and improved the properties of the nanofibers. The viscosity of the solution depended on the casein concentration, and bead-free nanofibers were obtained at a concentration higher than the entanglement concentration (C-e).

Summary: Phycocyanin, a protein prone to degradation under acidic conditions and unstable at high temperatures, has limited application in food. This study successfully combined phycocyanin with whey protein isolate using protein coprecipitation and chitosan coating to form composite particles, which maintained the color and colloidal stability of phycocyanin. The composite particles showed minimal color changes and retained high pigment retention rates after heating. Furthermore, the composite particles exhibited excellent antioxidant capacity. This breakthrough expands the application of phycocyanin in acidic beverages and other food forms.

Summary: This study investigated the synergetic gelation of curdlan gum (CG) and gellan gum (GG) at different ratios. The optimal gelation was achieved at a mass ratio of 1:1 and a total concentration of 0.6%. The gel properties were influenced by the CG/GG ratio, with the strongest gel observed at a ratio of 5:5. The improved gel properties were attributed to hydrogen bonds between CG and GG. The CG/GG binary composite gel exhibited increased water holding capacity as the CG/GG ratio decreased. Furthermore, the microstructure of the CG/GG gel was denser and more homogeneous, supporting its stronger gel rigidity and water holding capacity.
