What You Need to Know
The process relies on ambient solar heat (25–35 °C) to evaporate water, lowering water activity beneath 0.6 and halting microbial growth. Banana leaf phenolics such as catechins diffuse into the flesh, scavenging free radicals and slowing lipid oxidation. Concentration of free amino acids, nucleotides and mild Maillard‑type reactions enhance umami and salt perception.
