“…All the samples were allowed to cool, and the final electrical conductivity (C 2 ) was measured at 20 • C. Electrolyte leakage (EL) was evaluated using the formula EL = (C 1 /C 2 ) × 100. CI to the outer and inner rind of the pomegranate was assessed visually as we recently described [7], with 9 trained evaluators scoring the affected pomegranate surface. Scores were displayed on a 5-point scale: 1 = no damage; 2 = 1-10% surface damaged; 3 = 11-30% surface damaged; 4 = 31-50% surface damaged; 5 = >50% surface damaged.…”

“…In recent years, different methods or strategies have been used and/or studied to help minimize the presence of CI in pomegranate fruit. For example, it has been observed that physical barriers such as packaging or wrapping with different films successfully maintain quality traits during refrigerated storage [ 6 ] and also reduce CI at suboptimal temperatures [ 7 ]. With respect to chemical treatments, salicylic acid (SA) has the potential to decrease both ethylene production and the respiration rate, maintaining pomegranate quality during postharvest storage at low temperatures [ 8 ].…”

Spain is one of the main contributors to global pomegranate production. Pomegranate presents a challenge for preservation at suboptimal temperatures. Preserving this fruit for an extended period is challenging due to its susceptibility to chilling injury (CI). For this reason, we have examined different postharvest treatments to extend the pomegranate shelf life and their potential impact on reducing CI. For this reason, two postharvest treatments have been applied: 1-Methylcyclopropene (1000 nL L−1 1-MCP) and methyl jasmonate vapors (0.01 mM MeJA), a natural elicitor found in many plant organs that induces a wide range of physiological processes, including the activation of defense mechanisms against stress. Following the application of these treatments and subsequent fruit storage at 2 °C for 90 days, maintenance of firmness and membrane integrity was observed. Additionally, a positive synergic effect was observed in these quality traits when combining both substances (1-MCP + MeJA), especially with regard to delaying weight loss, the external color evolution, and total polyphenol accumulation. On the other hand, MeJA treatment alone or in combination with 1-MCP also increased the anthocyanin content in arils, thereby enhancing the fruit quality. In general, the best results were observed when these two different technologies were applied as a combined treatment, especially in terms of maintaining quality traits such as fruit firmness and total acidity and reducing weight loss and CI. This is the first time that these two substances have been tested together in any fruit species, and their simultaneous application in the same container represents an innovative approach that could be an interesting tool for commercial purposes.
