Abstract:

This study investigated the structural and functional characteristics of soy protein isolate (SPI)-based emulsion-aggregated gels produced at different SPI-to-oil ratios with or without vacuum-assisted (VA) treatment. VA treatment markedly enhanced gel cohesion, reduced porosity, and produced denser, smoother microstructures, as confirmed by SEM analysis. Optimal formulations (S3O7 and S4O6) exhibited balanced textural properties, superior freeze-thaw stability, and higher absolute zeta potentials, indicating improved colloidal and structural stability. Protein solubility analysis revealed increased hydrogen bonding, disulfide crosslinking, and hydrophobic interactions after VA treatment, supporting a more cohesive and ordered protein network. Compared to conventional tofu, the developed gels demonstrated improved structural stability, enhanced water retention, and greater protein density. These findings highlight vacuum-assisted emulsion aggregation as an effective strategy for tailoring microstructure and stability in protein-based gel systems.

Detergent Purification of Membrane Proteins

Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...
