What You Need to Know
The steaming process induces protein denaturation (60–70 °C) and starch gelatinization (65–70 °C), while the high humidity (~70–80 %) prevents surface drying. Taro leaves release tannins that can be leached by prolonged steaming, reducing astringency. The anaerobic, high‑temperature environment suppresses bacterial growth, and the fibrous leaf barrier limits oxidation, extending shelf life.
