原始语种摘要: Freshly harvested baby leaf lettuce ( Lactuca sativa L. cv. Red Romaine) leaves were packaged with 1,300, 20,000, 40,000, or 100,000 cm3/m2/day/atm oxygen transmission rate (OTR) packaging films as modified atmosphere packaging (MAP), as well as perforated film, then stored at 8 °C with 90% relative humidity in order to determine the most suitable OTR film. The results indicated that the 20,000 cm3 OTR film modified the atmosphere created in the package so that it consisted of 19.25-19.95% oxygen, 1.55-4.90% carbon dioxide and 5.10-8.06 μl/l ethylene. Changes in quality of the lettuce, including weight loss, visual quality, chlorophyll concentration, colour (L*, a*, b*, chroma and hue angle) and off-odour were lowest under the 20,000 cm3 OTR film. Leaves under the 20,000 cm3 OTR film also...
