Enzymatic Cross-Linking of β-Lactoglobulin: Conformational Properties Using FTIR Spectroscopy
TL;DR: The changes in the C-H stretching region clearly indicate that hydrophobic interactions are altered upon enzymatic cross-linking by transglutaminase, and denaturing by thermal treatment dissociates the beta-sheets in the native structure, leading to new intermolecular beta- sheets being formed.

Polymerization and Gelation of Whey Protein Isolates at Low pH Using Transglutaminase Enzyme
TL;DR: Dynamic and steady shear rheology is used to examine the synthesis of low-pH whey protein gels obtained through a two-step process and finds the enzyme-catalyzed gels to have significantly higher yield/fracture stress and strain compared to cold- set gels prepared without enzyme or conventional heat-set gels.

Modulation of hydrophobic interactions in denatured whey proteins by transglutaminase enzyme
Ahmed S. Eissa,Saad A. Khan +1 more
TL;DR: The role of enzyme crosslinking in mediating formation of hydrophobic association in chemically denatured whey protein isolates (WPI) is examined in this paper, with and without transglutaminase enzyme.

Acid-induced gelation of enzymatically modified, preheated whey proteins.
Ahmed S. Eissa,Saad A. Khan +1 more
TL;DR: The results indicate that factors responsible for fracture properties may not be apparent in the gel microstructure and linear viscoelastic properties.

Effect of SDS on whey protein polymers. Molecular investigation via dilute solution viscometry and dynamic light scattering
TL;DR: In this paper, the effect of Sodium Dodecyl Sulfate (SDS) on whey protein polymers was assessed and it was shown that the polymer molecules got larger upon SDS addition as revealed by both viscometry and dynamic light scattering.
