Description
Steaming masa dough in banana leaves gelatinizes corn starch at ~100 °C, yielding a firm yet pliable texture with leaf‑derived aromatics.
Technical
During steaming, the heat causes the crystalline structure of amylopectin and amylose to swell and rupture, allowing water to penetrate and form a gelatinized matrix. The banana leaf releases volatile compounds such as methyl‑2-(3‑methylbutyl)cyclohexanol that infuse the dough, while phenolic antioxidants may reduce oxidation. The process also inactivates mycotoxins and spoilage microorganisms, providing mild preservation.
