Fig. 5.1. Conceptual model for sensitivity range for different CI symptoms at a given
time–temperature regime (from several sources). Appearance of various symptoms
described in each study was plotted on a time–temperature axis. Each symptom was
grouped by identifying a line of the first time of appearance of a symptom at a tem-
perature. Potential sensitivity of each injury symptom induced by the storage condition
described by the time and temperature axis to chilling. Data were retrieved from Kader

longer than others to develop, while some are intermediary, and some
are slow for the specific CI symptoms to become apparent.
Starting with the fastest-appearing problem, it would appear that any
temperature below 13◦C has an adverse effect on flavor even when
tomatoes are stored for as little as 2 d. Relatively, rapidly appearing
injury symptoms include blotchy red coloration and excessive soften-
ing. Blotchy red coloration can occur after a week at 7–8◦C or, alterna-
tively, only 3 d at 3◦C. Excessive softening can occur after 3 d at 2.5◦C
but only after 7–8 d at 10◦C.
Pitting or sunken patches followed by decay seems to have interme-
diary sensitivity. Pitting is not generally found until after 7–8 d at 2.5◦C,
11 d at 5◦C, and 28 d at 9◦C. Pitted tissue is often an ideal entry point for
microorganisms, especially fungal saprophytes. Although an increase
