What You Need to Know
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.
Transforms standard butter emulsions by introducing flavor-active compounds that simultaneously stabilize the sauce structure.
