| Abstract |
In order to maintain the qualities at postharvest stages, Korean red leaf lettuces (Lactuca sativa L. cv. Tojong-mats) were packaged with different films or perforations such as perforated polypropylene with 1320 small-sized holes (PPP-1320-hole), perforated polypropylene with 4 large-sized holes (PPP-4-hole), non-perforated polypropylene (Non-PPP), non-perforated polypropylene with anti-fogging properties (Anti-Fog-PP) or without packaging (control) and stored at 10 °C up to 16 days. Minimum water loss was observed in both non-perforated films (< 3%) compared to 35% in control at the end of storage. Significant increase in CO2 and simultaneous decline in O2 concentration were recorded in both non-perforated films. A gradual decline in hue angle (h°) and SPAD (Soil-Plant Analyses Development) chlorophyll meter values was found in all samples during storage while the color difference (ΔE*) values showed opposite trend. However, Anti-Fog-PP treatment exhibited the least ΔE* values throughout the storage. The contents of chlorophyll a (Chl a), chlorophyll b (Chl b) and total chlorophyll (total Chl), decreased gradually in all cases with a comparatively higher declines in Non-PPP treatment on 6 days, in PPP-4-hole treatment both on 12 and 16 days. Anti-Fog-PP treatment exhibited the lowest chlorophyll degradation and least changes in anthocyanin content until the end of storage. Lettuces received scores for maintaining marketable limits up to 2, 4, 6, 12 and 16 days under control, PPP-1320-hole, PPP-4-hole, Non-PPP and Anti-Fog-PP packaging treatments, respectively. Results indicated that Anti-Fog-PP treatment could provide better postharvest qualities along with extended marketable life for about 2 weeks during storage at market display temperature. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 17 April 2018.
All research outputs
#15,505,836
of 23,043,346 outputs
Outputs from Journal of Food Science and Technology
#639
of 1,452 outputs
Outputs of similar age
#212,904
of 333,156 outputs
Outputs of similar age from Journal of Food Science and Technology
#38
of 111 outputs
Altmetric has tracked 23,043,346 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,452 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.4. This one is in the 39th percentile – i.e., 39% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 333,156 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 111 others from the same source and published within six weeks on either side of this one. This one is in the 16th percentile – i.e., 16% of its contemporaries scored the same or lower than it.
