What You Need to Know
The process relies on sustained temperatures of 70–90 °C to gelatinize starches and denature proteins, while the high humidity (50–60 %) from the banana leaf prevents drying. Microbial activity on the leaf surface produces lactic acid, lowering pH to 4.5–5.0 and contributing to a tangy profile. At the final phase, temperatures can rise above 120 °C, initiating Maillard reactions that develop complex browning and flavor compounds.
