Description
Maillard-reacted milk proteins and caramelized lactose create stable nucleation sites for water-in-fat emulsions.
Technical
Heat-induced degradation of milk solids (casein/whey) produces pyrazines and furans while creating hydrophobic/hydrophilic interfaces. The resulting amphiphilic compounds (like lactones and diacetyl) lower interfacial tension between aqueous and lipid phases.
Culinary Significance
Transforms standard butter emulsions by introducing flavor-active compounds that simultaneously stabilize the sauce structure.
