Studies on optimization of ripening techniques for banana

Area of Science:

• Horticulture
• Postharvest Physiology
• Plant Science

Background:

• Banana ('Grand Naine' cultivar) fruits harvested at the green mature stage require controlled ripening for optimal quality.
• Postharvest losses due to improper ripening impact the banana industry.

Purpose of the Study:

• To evaluate the efficacy of ethylene gas and ethephon treatments on ripening 'Grand Naine' bananas.
• To determine optimal concentrations for achieving desirable fruit quality and shelf-life.

Main Methods:

• Fruits were treated with ethylene gas (100 ppm for 24 h) or ethephon solutions (250–1000 ppm for 5 min).
• Ripening occurred in a controlled chamber (16–18°C, 90–95% RH).
• Quality attributes (color, flavor, firmness) and shelf-life were assessed compared to untreated controls.

Main Results:

• Ethylene gas (100 ppm) and ethephon (500 ppm) treatments resulted in adequate ripening within 4 days.
• Treated fruits exhibited uniform color, pleasant flavor, and desirable firmness.
• Control fruits showed poor color and texture, indicating inadequate ripening.

Conclusions:

• Ethylene gas and ethephon treatments are effective for ripening 'Grand Naine' bananas.
• Optimized treatments enhance fruit quality and shelf-life, reducing postharvest losses.
• These methods offer economic benefits for banana growers and traders.
