Influence of harvesting season and storage temperature on postharvest quality of fresh 'TaNee' banana leaves
Banana leaves are widely used for food-wrapping, food-serving, packing material or decorative and symbolic purposes both in Thailand and overseas. With the high demand, both fresh and frozen banana leaves have great potential for export. However, loss of quality and freshness of banana leaves can affect the postharvest shelf life and is caused by many factors. Harvesting season and storage temperature are important factors to impact the quality of banana leaves. The objective of this study was to determine the effect of harvesting season and storage temperature on quality changes and storage life of fresh 'Tanee' banana leaves. This work was carried out on banana leaves harvested during the cool, hot and rainy seasons of Thailand. The harvested leaves were sorted, cleaned and packed in plastic baskets prior to storage at 2, 5, 10, 15°C and ambient temperature. The results showed that banana leaves stored at lower temperatures had the least weight loss, freshest and longest shelf life. The optimum storage temperature for fresh 'Tanee' banana leaves was at 5°C as the storage at 2°C could lead to the browning on the surface of leaves at a short period. Moreover, the harvesting season also affected to the storage life of banana leaves. The leaves harvested in a cool-season had the longest storage life of 30 days at 5°C while those in hot and rainy-seasons had shorter storage life.
