Onions may look sturdy, but they are sensitive to moisture and temperature changes. Poor handling can trigger sprouting, mould, soft rot and internal breakdown. A disciplined cold chain keeps onion exports firm, dry and mild from packhouse to port.

Managing temperature and airflow

Yellow and red onions store well at low but above-freezing temperatures with good ventilation. Humidity must be kept low enough to prevent sprouting and decay, while air circulation removes moisture released by the bulbs. Balanced conditions extend shelf life dramatically.

Huasheng's export cold chain

After curing and grading, our onions are held in ventilated storage and loaded with proper airflow into refrigerated containers. Ventilation settings are matched to the destination market and voyage length, protecting quality during sea freight.

Choosing an onion supplier

Ask about curing time, storage temperature, and container ventilation. A supplier that actively manages the cold chain can supply consistent, long-keeping onions that arrive ready for retail or wholesale distribution.
