What You Need to Know
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.
