Implication

Experimental study demonstrates surface hydrophobicity predicts emulsifying properties in heat-denatured food proteins, suggesting joint utility with solubility for functionality.

Key Points

Investigate how thermal denaturation affects the emulsifying properties of selected food proteins and assess protein surface hydrophobicity as a predictive indicator of functional performance.
Evaluated the emulsifying properties of selected food proteins following heat-induced denaturation.
Measured protein surface hydrophobicity and solubility to determine their individual and combined predictive utility for emulsifying activity, emulsion stability, and fat binding capacity.
Heat denaturation did not uniformly impair protein emulsifying properties and substantially improved them in select protein systems.
Surface hydrophobicity independently predicted emulsifying performance, whereas protein solubility alone failed to serve as an effective predictor.
The combination of surface hydrophobicity and solubility yielded the most accurate predictions for emulsifying activity, emulsion stability, and fat binding capacity.
