Researchers at Sultan Qaboos University in Oman, led by Laila al‑Yahyai, have developed a natural and safe method to extend the shelf life of bananas. Covering bananas with a thin layer of olive oil or Moringa oil helped keep them fresh for up to 12 days.
Experiments were conducted with Cavendish and Milk Banana varieties at 15°C and 25°C. The oil coating slowed moisture loss, maintained firmness, and preserved the green peel color. The effect was particularly strong under cooler conditions, similar to transport storage.
Scientists highlighted that this inexpensive, eco-friendly, and edible method can replace synthetic coatings and reduce post-harvest losses, supporting food security.
As a reminder, previously Australian scientists discovered the simplest method to keep mangoes fresh.
