Possible Interaction: Gelatin and Sodium Dodecyl Sulfate

“Triton-treated samples were able to form a firm hydrogel under the appropriate conditions, while the use of SDS had detrimental effects on the gelation properties of the hydrogels.”

“Addition of SDS to WPI increased gelation while reducing aggregation.”

“However, the presence of SDS stimulates both attractive and repulsive forces whose relative dominance controls the viscoelastic properties and gelation.”

“Fourier transform infrared and differential scanning calorimetry analysis indicated that gelatin and SDS intimately interacted via electrostatic and hydrophobic interactions.”

“The triple helix structure of gelatin is decomposed to random coil upon the binding of SDS.”

“The adsorption capacity of CSB (4 g/L SDS gelation) for MB (100 mg/L) was 129.44 mg/g, and it decreased significantly with increasing SDS concentration during gelation.”

“On the whole, the research indicates that the existence of SDS not only decreases the droplet diameters and centralizes the droplets size distribution, but also accelerates coacervation of gelatin and gum arabic to reach the core droplet/water interface, forming no aggregating microcapsules.”

“When SLS is used in the medium, dissolution is significantly hampered due to the formation of a less soluble precipitate of gelatin.”

“ SLS interacts with gelatin to form a less-soluble precipitate at pH < 5.”

“However, if SDS was added after gelation , the protein layer was observed to fracture, consistent with the behavior of a solid phase.”
