Product Description

Fresh Onion Storage

Onions should not be stored unless adequately cured(dried) either in the field or by artificial means. It is necessary to dry the neck tissues and outer scales until they rustle when handled, otherwise, the bulbs will rot in storage. They can be artificially cured by blowing heated air at 110-115F (43-46C) through mesh bags for 8-12 hours or longer.


Onions are held in 60 lb. sacks, slatted crates, and pallet boxes holding about tons of loose onions, in bins, or in large bulk storage. When in sacks, these should be loaded cross-wise or "air-stacked" 5-6 high. The stacks should be set on floor racks. Individual stacks should be separated a few inches to allow free air circulation. Sufficient Airflow of product is adequate. When in crates or pallet boxes, they can be stored one on top of the other to make full use of the storage space. Onions should be held at 32F (0C) for maximum quality and shelf life. Storage at ambient temperature may be acceptable for short periods (1-1.5 months) depending on the variety.
