Effects of anti-UV film and MAP on fresh-cut iceberg lettuce

Researchers at the University of Basilicata in Italy studied the shelf-life of fresh-cut iceberg lettuce. They tested a packaging film manufactured with and without anti-UV compounds, and used two different protective atmospheres (N₂/CO₂ 70/30% and Ar/CO₂ 80/20%). The samples were stored at 6 °C under artificial light by using real supermarket refrigerated exposition stands.
Results show that the use of an anti-UV film always causes a lower quality decay of the product. The best results were obtained when the anti-UV film was utilized in association with the packaging atmosphere consisting of Ar and CO₂ (80/20%) gas mixture. An article about the research is published in Acta Alimentaria.
