Eden Solutions for Banana Ripening

Bananas purchased on the market are usually ripe, with an attractive golden-yellow peel. However, to prevent bananas from spoiling during distribution, they are generally picked and refrigerated while still green. Upon arrival at their destination, since bananas ripen slowly under natural conditions, ripening treatment is required to solve the problem of short shelf life and difficult transportation.

Spray-on ripening agents are being phased out

China’s more traditional banana ripening method involves spraying a ripening agent containing ethylene to promote fruit ripening and colour development. The process of the peel turning from green to yellow, ripening from the outside in, generally takes about nine days. However, during the spraying process, uneven application is common, causing different parts of the same banana to ripen at different times. Bananas ripened this way are inconsistent in appearance, prone to black spots, and easily damaged by slight friction during transport and handling. Spray-on ripening methods have been gradually phased out and banned in Europe, the United States and other countries.

Eden’s temperature-regulated ripening solution is greener and safer

Temperature-regulated ripening

Building on cold storage preservation, the Eden ripening solution regulates the fruit ripening cycle by controlling temperature, humidity, carbon dioxide and ethylene concentration in the storage environment (the banana ripening cycle is typically 4-8 days), and improves airflow inside the storage through forced differential pressure, allowing the fruit to heat evenly. Fruit ripened through temperature regulation has a uniform, consistent colour, good texture and higher sweetness.

- Transfer bananas from the cold storage to the ripening room, where the temperature is maintained at 16°C~18°C and humidity is kept above 90%.

- Release ethylene gas to activate the ethylene synthase inside the bananas and promote pulp ripening. During this stage, the room temperature is raised and maintained at 18°C or 19°C with humidity above 90%. (From the start of ethylene release to complete gas emission takes approximately 24 hours.)

- 24 hours after ethylene release, dilute the ethylene gas, adjust the carbon dioxide concentration and inject fresh air to accelerate pulp respiration and promote intense organic transformation in the pulp. During the ripening stage, the CO₂ concentration must not exceed 5000 ppm.

- Lower the temperature to 14°C~16°C and hold for 3-4 days until ripening is complete.

Easy cleaning

The unit cooler equipped in the Eden ripening solution has successfully solved, through structural innovation, two persistent problems of traditional unit cooler fans: difficulty of cleaning and the inability to get them thoroughly clean. The cooler features an openable mesh guard design, allowing one person to complete disassembly and reinstallation after cleaning in just two steps.

Integrated lighting system

Considering the space utilisation of the ripening room, the Eden ripening solution can also meet in-room integrated lighting needs by combining the unit cooler and the lighting system into one unit, enabling rapid one-time deployment.

Eden provides a green and safe ripening solution that can be applied to fruits that are particularly difficult to store and preserve, such as bananas and avocados.
