Summary

Cold storage of mature-green tomato (cv. Caruso) fruits at 1 deg C for 22 days resulted in chilling injury symptoms which developed only after rewarming. The main molecular species of phosphatidylcholine was not affected during cold storage or after rewarming. However, during cold storage the minor molecular species shifted significantly towards increased unsaturation. This trend was only partly reversed during rewarming. The presence of these polyunsaturated species and their breakdown products may have induced membrane destabilization and dysfunction upon returning the fruits to ambient temperature.
