Iceberg lettuce is one of the most nutritionally important vegetables and plays a great role in economic relevance in the world, being highly consumed both at home and in fast food chains. Additionally, it is valued for its crisp texture and mild flavor. However, the natural perishability of lettuce is facing greater problems during storage and transportation to long-distance marketing. Previously conducted work revealed that the quality of iceberg lettuce is affected by various factors, including maturity stages and packaging materials. This review explores the literature available on the implications of developmental levels and packaging materials on the quality of iceberg lettuce for export-oriented marketing systems. The study provides insight into producers of vegetables and fruits, especially lettuce; harvesting iceberg lettuce at an immature stage could easily damage and deteriorate quickly due to moisture loss and high physiological processes. Overmatured similarly reduces quality because of russet spots, pinking formation, and physiological disorders. Improper packaging materials also affect the quality and shelf life of lettuce through excess loss of water and by restricting the circulation of air, then accumulating high carbon dioxide. Most of the researchers reported harvesting iceberg lettuce on the 59-65 days based on the day after planting and packing with modified atmospheric packaging; corrugated fiberboard with high- and low-density polyethylene liners and plastic crates is very paramount. This review concluded that harvesting iceberg lettuce at the optimal maturity stage and using appropriate packaging materials are very paramount to maintaining the quality of lettuce for marketing, particularly for export purposes.
结球生菜是营养最为重要的蔬菜之一，在全球经济中具有重要地位，在家庭和快餐连锁店中消费量都很高。此外，它还因其爽脆的口感和清淡的味道而受到青睐。然而，生菜的自然易腐性在储存和长途运输到市场的过程中面临着更大的问题。此前的研究表明，结球生菜的品质受到多种因素的影响，包括成熟阶段和包装材料。本综述探讨了有关发育水平和包装材料对面向出口的营销体系中结球生菜品质影响的现有文献。该研究为蔬菜和水果生产商，尤其是生菜生产商提供了见解；在未成熟阶段收获结球生菜，由于水分流失和高生理过程，很容易受损并迅速变质。同样，过度成熟也会降低品质，因为会出现赤褐色斑点、粉红色形成和生理失调。不合适的包装材料也会影响生菜的品质和保质期，水分过度流失以及空气流通受限，进而导致二氧化碳积聚。大多数研究人员报告说，根据种植后天数，在第59 - 65天收获结球生菜，并采用气调包装；带有高密度和低密度聚乙烯衬里的瓦楞纤维板以及塑料板条箱非常重要。本综述得出结论，在最佳成熟阶段收获结球生菜并使用合适的包装材料对于保持生菜用于销售，特别是出口的品质至关重要。
