Dataset for modification and development of thermoplastic whey protein isolate using surfactants: preliminary screening and interaction parameters for whey protein isolate modification based on Hofmeister series

The dataset includes viscosity measurements of WPI formulations containing sodium dodecyl sulfate (SDS), cetylpyridinium chloride (CPC), and benzalkonium chloride (BC) before thermal denaturation; dynamic light scattering (DLS) data used to evaluate changes in protein size and aggregation; and experimental data from the preparation and characterization of WPIT formulations.

The characterization dataset includes Fourier-transform infrared spectroscopy (FTIR), circular dichroism (CD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and rheological measurements. The data provide information on changes in protein structure, thermal stability, and viscoelastic behavior resulting from surfactant incorporation.
