Abstract
The nutrient contents of pumpkins depend on many factors, including the species, climate, soil type, and plant part. The nutritional compositions of five pumpkin cultivars (red boujjang, mini hong, mini gold, boujjang, and yakhobak) were investigated. To analyze the nutrient contents of the edible parts, the other parts (seeds, skin, and stem) of each pumpkin were removed. The results showed that the proximate compositions of the edible parts of the pumpkins ranged from 74 to 87 g per 100 g for moisture, 1.6 to 3.2 g per 100 g for crude protein, 10.1 to 20.7 g per 100 g for carbohydrate content, and 2.0 to 3.4 g per 100 g for total dietary fiber. The proximate contents of the pumpkin samples were not significantly different. The thiamine contents of the pumpkins, except for red boujjang, varied from 0.03 to 0.15 mg per 100 g, but that of red boujjang had the highest level (0.60 mg per 100 g). The vitamin C contents of the pumpkins, except for boujjang, ranged from 13.0 to 14.0 mg per 100 g, but that of boujjang was the highest (49.0 mg per 100 g). In particular, yakhobak showed the highest total carotenoid and folate levels (279.5 and $74.0{\mu}g$ per 100 g, respectively). These results will be useful for coming up with better pumpkin varieties through breeding, and established the nutrient compositions of pumpkins.
