Effects of vacuum cooling and packaging films on the shelf life of "Salinas" lettuce.
Author(s) : ARTÉS F., MARTINEZ J. A.
Summary
The effects of vacuum cooling and several types of polypropylene films on the quality of modified-atmosphere packaged iceberg lettuce (Lactuca sativa L. cv. Salinas) were evaluated after 1 week of storage at 2 deg C and after additional 2.5 days at 12 deg C. Lettuces were grown and packed under commercial conditions using conventional perforated polypropylene film and new sealed polypropylene bags. In all treatments, vacuum-cooled heads showed higher visual quality score than those of non vacuum-cooled heads, either after 1 week at 2 deg C or after additional shelf life. Vacuum-cooled lettuce heads packaged in 0.025 or 0.050 mm individual sealed polypropylene bags showed the best results as measured by scoring weight loss, wilting, physiological disorders (russet spotting and pink rib), bacterial decay and overall visual quality.
