Ethylene in Agriculture (Ripening)

Ethylene gas is a natural plant hormone that plays a critical role in fruit ripening. Applying ethylene to unripe fruits allows producers to control and standardize ripening, improving quality and reducing waste.

How It Works

• Natural Process: Fruits produce ethylene naturally, triggering ripening.
• Controlled Application: Ethylene gas is introduced in ripening rooms to accelerate and harmonize the process.
• Ripening Room Conditions: Typically maintained at ~21°C (70°F), 85–95% humidity, with regulated ethylene and CO₂ levels.

Benefits

• Faster, more consistent ripening.
• Improved taste, aroma, and color.
• Extended shelf life and reduced post-harvest losses.
• Year-round availability, including off-season fruits.

Safety & Environmental Notes

• Overexposure can cause over-ripening or spoilage in sensitive fruits.
• Proper ventilation and gas monitoring are essential.
• Industrial-scale use should follow environmental guidelines.
