Description
Roasting Bambara groundnuts over an open flame at moderate temperatures denatures anti‑nutrients and develops a nutty flavor.
Technical
The heat denatures lectins and reduces trypsin inhibitors while driving Maillard chemistry between free amino acids, especially lysine, and reducing sugars. This reaction produces pyrazines and furans that give the characteristic nutty aroma, and also generates acrylamide precursors if temperatures exceed 200 °C. Simultaneously, phytic acid is hydrolyzed, improving mineral bioavailability.
Science
