Abstract

This study had been done on the young ginger (Zingiber officinal Roscoe) rhizome to measure the effect of treatments and storage durations to the physical wound. The aim of this study was to reduce the physical wound in young ginger rhizomes during postharvest handling. By having the knowledge about the physical characteristics wound in young ginger rhizomes, the maximum level of damage could be reduced. Young ginger rhizome was harvested and treated with the abrasion, compression, abrasion and compression injuries. The young ginger rhizome without any injury treatment was used as the control. After being treated, the rhizomes were stored at room temperature for the periods of 0, 2, 4, 6, and 8 weeks. Completely random design was used in this study with a factorial arrangement of treatments by using 4 different of injuries (control, abrasion, compression, abrasion and compression) and the period of storage durations (0, 2, 4, 6 and 8 weeks). There were 5 replicates used per treatment in each experiment. The result showed that abrasion and compression would bring damage to the rhizome that will result in weight loss, increasing of firmness, defect on the visual appearance and changes on the parenchyma cell structure. Among the postharvest handling, abrasion and compression injuries stimulation gave the most defected visual appearance to the young ginger rhizome. The result showed that the highest weight loss (43.07%) was the rhizome treated with abrasion injury stimulation while the lowest weight loss (22.96%) was fresh rhizome (control). The result showed that, abrasion and compression injuries stimulation gave the most firmness to the young ginger rhizome with the increasing of storage durations. Besides that, the rhizome showed the increase of injury after storage. However, the destruction and ruptured only happened to the rhizome treated with abrasion, abrasion and compression injuries stimulation. In addition, the compress's rhizome and the fresh rhizome (control) did not show any destruction and rupture. This study showed that there were correlation between treatments and storage durations to the physical wound.
