Impact of storage condition on postharvest preservation of fresh Bambusa sp. Shoot

Abstract

This research was aimed to study postharvest senescence of fresh Bambusa sp. shoot. The harvested bamboo shoots were packed in linear low-density polyethylene (LLDPE, 0.07 mm thick) bag and stored in 2 conditions: Ambient (29±3°C) and refrigerated temperatures (5±3°C). The physical and chemical properties during the 7 days storage were investigated for postharvest quality management. The storage of the bamboo shoots at ambient greatly affected the physical and chemical properties (weight loss, discoloration, reducing sugar content and total acidity content) compared to the refrigerated storage. Under the ambient storage, critical weight loss of shoots (approximately 5) was recorded at day 4 storage along with the darkening of the basal section. Moreover, the reducing sugar rapidly decreased to 50% of the initial at day 2 storage. Sensory evaluation was conducted, and consumers were able to accept bamboo shoots stored at ambient up to one day of storage. On the other hand, bamboo shoots stored in refrigerated up to 7 days were acceptable. This is due to the quick change of color and odor of the bamboo shoots which can be the quality indicators of the harvested shoots.
