摘要

This research was designed to examine the alterations in fruit quality and the characteristics and pathological developments of eight distinct cherry laurel genotypes stored at 0 °C and 90% relative humidity over 60 days. Samples were taken at 15-day intervals to monitor and analyze the progression of quality changes and associated losses during storage. At the end of 60 days of storage, 1.92–12.46% decay was determined in cherry laurel, except for genotype 3. After the storage period, genotype 4 exhibited the most significant weight loss (4.92%), while genotype 1 demonstrated the least weight loss (1.38%). Throughout storage, the highest values for hue angle (h°), total soluble solids, and titratable acidity were observed in genotypes 3 and 4. In contrast, the lowest values for breaking force and chroma (C*) were recorded. Genotype 3 exhibited the highest average total phenol content and antioxidant activity, with 312.0 mg GAE/100 g values and 125.70 µmol TE/g fresh weight, respectively. After the storage period, genotype 8 received the highest overall score, while browning was observed in genotypes 3 and 4. The results highlighted significant variations in cherry laurel fruits’ physical, chemical, and biochemical characteristics. While all genotypes were suitable for storage for 45 days, genotypes 2, 7, and 8 demonstrated the potential for successful storage for up to 60 days.
