Controlled atmosphere preservation is a technology developed on the basis of refrigeration. Through controlled atmosphere equipment, the gas composition inside storage facilities is processed and regulated to reduce oxygen levels and increase nitrogen concentration, placing fruits and vegetables in a low-oxygen “dormant” state.
In this state, the respiration intensity and natural consumption of fruits and vegetables are reduced, while the production of ethylene — a ripening-promoting hormone — is inhibited. Combined with refrigerated temperature control, this technology slows the consumption of nutrients, delays the aging process, extends storage life and shelf life, reduces storage losses, and helps maintain product freshness.
From July 13 to 16, 2026, the 2nd Asia Durian Conference in Vietnam will be held in Ho Chi Minh City. Yantai Keda Controlled Atmosphere Equipment Co., Ltd. will showcase its controlled atmosphere equipment solutions at the event. The company warmly invites fruit and durian industry professionals, buyers, and importers to visit Booth B01 for face-to-face discussions, business matching, and cooperation opportunities.

Controlled Atmosphere Container Technology for Durian
The controlled atmosphere durian container independently developed by Yantai Keda can extend the preservation period of tree-ripened durians to 35–40 days. This technology has helped open controlled atmosphere sea freight routes to China for tree-ripened Malaysian Musang King and Black Thorn durians.
By precisely regulating temperature, humidity, oxygen, CO₂, and ethylene levels, the container keeps durians in a low-oxygen dormant state, significantly extending freshness and shelf life.

Supported by six core technologies, Yantai Keda’s solution is designed to lock in freshness throughout the entire transportation process, helping durians maintain stable quality from orchard to consumer.
Tree-Ripened Durian Preservation: Six Core Technologies
1. Oxygen removal and nitrogen generation
Suppresses respiration and helps durians enter a dormant state.
2. Intelligent temperature control
Maintains precise and stable temperatures, supporting durian preservation under suitable low-temperature conditions.
3. Ethylene removal
Delays post-harvest ripening and extends both storage life and shelf life.
4. CO₂ removal
Helps inhibit mold growth and reduce spoilage losses during storage.
5. Precise humidity control
Locks in moisture, reduces dehydration, and maintains the freshness and sensory quality of the durian flesh.
6. Photocatalytic sterilization
Suppresses microbial activity throughout storage, creating a cleaner and safer preservation environment.
