Storage of oriental bunching onions.

Author(s) : LI W.

Summary

Weight loss, visual quality, leaf discoloration and growing point extension are the major storage quality parameters for oriental bunching onions. With oriental bunching onions stored in the open air (30 to 40% relative humidity) during winter, weight loss can be very high, sometimes greater than 50%. Temperature and relative humidity were the two most important limiting environmental factors affecting the storage life of oriental bunching onions. A combination of low temperature and high relative humidity is ideal for storage of oriental bunching onions. Control of temperature with refrigeration is preferred, if economically feasible. Similarly, maintaining humidity to reduce moisture loss will improve quality. Atmosphere modification was found to be more effective than air storage in extending the shelf life of oriental bunching onions. Growing point extension was also slowed by modified atmosphere storage.
