This study was performed to clarify the component characteristics of bananas cultivated in a high-altitude region. After bananas cultivated in the 3 different altitude (high : 1000 m, middle : 500m, low : 0-20 m) were ripened at 20 deg C, chemical components associated with flavor and taste were compared at 3 ripening stages. Water contents of bananas cultivated in the high- and middle-altitude regions were lower than those in the low-altitude region. Starch contents of the bananas in the high-altitude region were the lowest among those in the 3 regions at a respective full-ripe stage. Sugar contents, sugar/acid ratio and isoamyl-acetate contents of bananas in the high- and middle-altitude regions rapidly increased until the optimum edible stage from early ripe stage, comparing with those of bananas in the low-altitude region. Particularly, the marked increases of sugar/acid ratio and isoamyl-acetate contents of the high-altitude region bananas were observed as compared with those of the other 2 regions. From these results, it was found that sweetness and flavor of bananas in the high-altitude region are stronger at the optimum edible condition than those of normal bananas in the low-altitude region.
