Moisture-Proof Corrugated Fibreboard Box Effectively Reduces Water Loss in Lettuce during Storage

摘要

Reducing water loss is important for the maintenance of the commercial quality of lettuce. In this study, we evaluated the water loss of lettuces that were not enveloped in any plastic films during storage for 6 days at 10°C using a moisture-proof corrugated fibreboard box (MPB) and a non-moisture-proof corrugated fibreboard box (control). We also evaluated the changes in SPAD value as an index of green colour, soluble solids, and ascorbic acid content during storage. The water loss in lettuce packaged into MPB was significantly lesser than that of control after 6 days of storage. In addition, MPB did not negatively influence other qualities of lettuce. Thus, we conclude that the use of MPB would contribute to keeping the quality of lettuces during distribution.
