Zhangwo Shunong (Zhejiang) Agricultural Technology, a company based in Liandu district of Lishui, Zhejiang province, is using advanced preservation technology to sell local waxberries to global markets.
Developed with the Future Food and Agriculture Department of Yangtze Delta Region Institute of Tsinghua University, the technology uses high-voltage, low-frequency electric fields and ultra-low temperature control maintained at minus 6 C . This extends waxberry freshness from the usual two to three days to 30 days, significantly reducing post-harvest losses.
The company's general manager said that with a 30-day shelf life, existing trade channels can already cover the European market.
Zhangwo Shunong delivers waxberries in bulk in batches of around 5,000 kilograms, targeting premium wholesale channels. It has established stable partnerships with over 400 supermarkets in Singapore and is steadily advancing into Southeast Asian markets and Europe.
The physical preservation method uses no chemical additives, helping meet high-end market standards.
The company also promotes local specialty varieties and is building a regional brand of "Liandu technology". Its waxberry base produced 200,000 kg of the fruit in 2025, with output expected to reach 750,000 kg by 2028, all destined for overseas markets.
The technology has also extended the shelf life of white loquats to three months and blueberries to over two months, with experiments ongoing for leafy greens and tomatoes. The company aims to become a comprehensive fresh produce supplier, bringing agricultural products from Liandu to global markets.
