# Shelf-life Assessment on European Cucumber Based on Accelerated Temperature-Humidity Stresses
## 3 Results
### Accelerated Life Testing and Reliability Estimations  
After the degradation analyses were complete, the accelerated life test was performed to acquire the failure times for the Temperature-Humidity model. To determine the postharvest parameters, six samples of European cucumbers with plastic covers and six samples without plastic covers were compared. The product was put under accelerated stress conditions to perform the accelerated life test, and weight loss was used to determine when it had failed. Failure times were determined, and life-stress relationships were then applied. Table 7 shows the stress levels and failure times under accelerated stresses (relative humidity and temperature) showing time to reach 5% weight loss for cucumbers with packaging covers and 0.7% for cucumbers without packaging covers (Failure Data). Figure 5: Correlation analysis of percentage of weight loss vs. firmness, \({}^{\circ}\)Brix, and pH with cover. Figure 6: Correlation analysis of percentage of weight loss vs. firmness, \({}^{\circ}\)Brix, and pH without cover. Using the accelerated life testing results, the impact of the influence of temperature, humidity, and plastic covers on the life or the cucumber was determined. Figure 7 illustrates how the various factors affect the life of the cucumber. This graph shows how life decreases as temperature increases. Furthermore, it is irrefutable that a cucumber's lifespan increases as the relative humidity rises. \begin{table}

Table 7: Accelerated failure times to reach the percentage of weight loss. Figure 7: Significance on factors over mean life degradation. Blue lines indicate the mean life at different levels of temperature, humidity and packaging cover. Moreover, through the accelerated life testing, the significance of the regression parameters was determined. The values in Table 8 demonstrate how temperature and humidity have an impact on the cucumber's lifetime since the \(p\)-value is below any alpha level. These factors contribute to the failure mode in some way. The accelerated life relationship was obtained following the discovery of the significant factors. Estimates of the parameters were obtained after analyzing a lognormal temperature-humidity graph. The connections for each stress level are shown in Figure 8. This connection demonstrates the rate of product failure over time.
