Implication

Experimental study demonstrates a strong link between molecular flexibility and emulsification in soy protein-glucose conjugates, highlighting mechanisms to improve plant-based food stability.

Key Points

To investigate the structure–function relationship between molecular flexibility and emulsifying properties in soy protein isolate and soy protein isolate–glucose conjugates prepared across various reaction temperatures.
Synthesized soy protein isolate–glucose conjugates via the Maillard reaction under wet conditions across five temperatures (50 °C, 60 °C, 70 °C, 80 °C, and 90 °C).
Characterized structural modifications using surface hydrophobicity (H0), intrinsic fluorescence spectroscopy, Fourier transform infrared spectroscopy, and free sulfhydryl group measurements alongside emulsifying property assays.
Molecular flexibility showed a strong positive correlation with emulsifying activity (r = 0.920, P < 0.01) and emulsion stability (r = 0.952, P < 0.01).
Surface hydrophobicity peaked at 70 °C, while free sulfhydryl content increased significantly (P < 0.05) and particle size decreased as the degree of grafting advanced.
Conjugation altered secondary structure by significantly increasing β-turn and random coil content while reducing α-helix and β-sheet structures.
