Summary

A study was conducted to determine the best conditions for long-term storage of leek stalks (Allium porrum) grown in Québec. The leeks were stored for 150 days at 1.5 deg C under a regular atmosphere (21% oxygen + 79% nitrogen) with relative humidity of about 80%, under a regular atmosphere with relative humidity close to saturation and under a controlled atmosphere (3% oxygen + 3.5% CO2 + 93.5% nitrogen) with relative humidity close to saturation. The results obtained from the experiment indicated clearly the superiority of controlled atmosphere over the other two atmospheres for long-term storage of the leek cultivars studied. After 150 days of storage, losses under controlled atmosphere were around 30%, compared with 70% and almost 85% for leeks stored under the two regular atmospheres, respectively.
