In the global agricultural value chain, post-harvest preservation has become a decisive factor for success. According to Vietnam’s Ministry of Agriculture and Rural Development, post-harvest losses still account for 20–40%, costing the economy USD 3.5–4 billion annually. Traditional cold storage only partially addresses this issue, as products still lose quality, deteriorate, or lose market value quickly.
CASS’s Controlled Atmosphere (CA) technology represents a major breakthrough, enabling produce to stay fresh 2–4 times longer while maintaining nearly all of its original color, crispness, flavor, and nutritional value.
Why Conventional Cold Storage Falls Short
Traditional cold storage slows down respiration by lowering temperature, but it cannot:
- Control O₂ and CO₂ concentrations, meaning the ripening process continues rapidly.
- Maintain optimal humidity, causing water loss, shriveling, and mold.
- Prevent sudden temperature changes during transport, which lead to chilling injuries and quality loss.
As a result, even under cold storage, most fresh produce lasts only 5–10 days before losing commercial value.
CASS CA Technology – Extending Freshness by 2–4 Times
CASS (Controlled Atmosphere Storage System) utilizes CA technology to precisely manage:
- Reduced oxygen levels – slowing down respiration and ripening.
- Safe CO₂ enrichment – suppressing microbial activity and pests.
- Optimized humidity – preventing dehydration and keeping produce plump.
- Stable temperature control – eliminating chilling injuries and quality degradation.
The results are clear:
- Shelf life extended 2–4 times compared to conventional cold storage.
- Natural color, crisp texture, authentic flavor, and nutritional value are preserved even after weeks of storage.
- Post-harvest losses reduced to below 5%, compared to 15–30% with traditional methods.
Economic Impact – Elevating the Value of Vietnamese Produce
Longer preservation provides businesses with:
- Flexibility in market timing, avoiding the need to sell quickly at low prices.
- Expanded export opportunities to demanding markets such as the EU, US, and Japan.
- Lower logistics costs, especially with CA-enabled refrigerated containers that make affordable sea freight possible.
- Up to 80% reduction in post-harvest losses, boosting profitability while protecting farmers’ hard-earned output.
CASS – The Future of Smart Agricultural Preservation
As Vietnam’s agricultural exports shift toward sustainability and value-added growth, CASS’s CA technology is the strategic key.
Beyond simply “keeping fresh,” CASS retains market value, reduces economic loss, and empowers Vietnamese produce to compete confidently on the global stage.
