Description
Carbonization of beef bones creates Maillard polymers and aromatic hydrocarbons that enhance pho broth complexity.
Technical
Pyrolysis of collagen and fats produces melanoidins (C15H18O6N2) and 2-methylfuran (C5H6O) while caramelizing bone marrow sugars (C6H12O6 → C18H9O9).
Culinary Significance
Develops foundational umami depth and amber hue in traditional pho while masking gaminess through carbon filtration.
