Effect of modified-atmosphere packaging on the quality of Iceberg lettuce during cold storage and shelf life.

Summary

Iceberg lettuce was harvested, vacuum cooled and transported with a refrigerated truck. Lettuces were placed in modified-atmosphere packs and placed: 1) in 0 deg C for cold storage trials; 2) in 20 deg C for shelf-life trials. Cold stored lettuces were stored for 20 days and analysed every 5 days, whereas lettuces in 20 deg C were stored for 7 days and analysed daily for the following quality parameters: total soluble solids (%), titratable acidity (g citric acid/100 g), colour (brightness), weight loss, consumable leaves, decayed or faded leaves and sensorial criteria like taste and crispness. According to our results, modified-atmosphere films have prolonged the storage life up to 20 days and shelf-life for 7 days, without any quality losses.
