Accuracy, reliability, and timing of visual evaluations of decay in fresh-cut lettuce
Fig 7
Decay progress calculated from 4,535 bags evaluated in eight different experiments.
Upper panel shows the mean decay and the standard deviation of decay calculated from means of eight experiments. Lower panel shows the frequency of lettuce samples in five bins. These bins were developed for simpler presentation of data. They combine visual ratings from the 0 to 10 rating scale, where 0 indicates no decay and 10 indicates complete decay.
