Symptoms and Sensitivity to Chilling Injury of Cantaloupe Melons during Postharvest

Pre- And Postharvest Attributes of Muskmelon Cultivars for Fresh-Cut Cubes

“…Each fruit was packaged in a sealed plastic bag with six perforations of 6 mm in diameter, stored for 18 d at 0 °C and ≥98% RH, removed from the bags and left for 3 d at 20 °C and ~55% RH, simulating long-range transport and a short marketing period (Krarup et al, 2009). After the 21-d storage period, the flesh color, soluble solids concentration, firmness, and weight were determined.…”

“…External CI symptoms were assessed after the 18-and 21-d periods using a modified version of the quality visual scale described by Yang et al (2003): 0, no damage to traces (0 to 1% surface symptoms); 1, mild (1.1 to 5%); 2, moderate (5.1 to 15%); 3, severe (15.1 to 30%); and 4, extreme (> 30%). Spots, superficial lesions, and soaked tissue were considered CI symptoms (Yang et al, 2003;Krarup et al, 2009).…”

“…After 3 d at 20 ºC, fruits from 'Diva', 'Fiji', and 'Glamour' still had no CI symptoms, while fruits from 'Colima' and 'PS4038' showed moderate to severe CI symptoms (Table 4). The genotypic variation in the sensitivity of cantaloupe melons to CI has been reported (Krarup et al, 2009), and ´Colima` and ´Glamour` were expected to present high and low sensitivity to CI, respectively (Laínez and Krarup, 2008;Krarup et al, 2009;Munira et al, 2013). Interestingly, Fiji, a cultivar with high quality traits, had no CI symptoms.…”

“…(Fogelman et al, 2011). Eventually, physiological disorders cause visible external symptoms on the epidermis of the fruit and increase susceptibility to diseases, impairing visual quality, aroma and flavor (Fallik et al, 2005;Krarup et al, 2009). Thus, CI becomes a limiting factor for the prolonged storage and long-distance transport of muskmelons at temperatures between 0 and 2 °C (Krarup et al, 2009).…”

“…Recent progress has made available a significant and increasing number of new cultivars of different muskmelon types (Eastern, Tuscan, Western Shipper, etc.). The choice of the appropriate cultivar or variety is one of the most critical production inputs for growers, but despite the increasing introduction of new varieties, there is less public variety testing than ever before (Williams and Roberts, 2002), and there are no known evaluations with the objective of selecting melons cultivars that combine specific pre-and postharvest characteristics as raw material for fresh-cut cubes (Krarup et al, 2009;Ohashi et al, 2009). …”
