Abstract

|
This study was carried out to investigate the food components of the fruit, cladodes, and flowers of freeze-dried Cheonnyuncho harvested from Yeosu, Jeonnam in Korea. The major components of freeze-dried Cheonnyun-cho in proximate composition were carbohydrates and crude ash. Ca, K, and Mg were the predominant minerals in Cheonnyuncho. Calcium content was higher in the fruit and cladodes than in the flowers. Two major amino acids, glutamic acid and aspartic acid, made up over 25% of the total amino acids in Cheonnyuncho. Palmitic acid and stearic acid were most abundant out of all the saturated fatty acids in Cheonnyuncho. The saturated fatty acid content of the fruit was higher than that of the flowers and cladodes. The major unsaturated fatty acid of Cheonnyuncho was oleic acid. The cladodes contained unusually high amounts of linoleic acid compared to the fruit and flowers. The major free sugar in the fruit was sucrose, whereas that of the cladodes and flowers was fructose. The total free sugar content was the highest in fruit, followed by cladodes. The most abundant organic acid in the fruits and cladodes was malic acid, while that of the flowers was citric acid. Vitamin A concentration was highest in the flowers whereas vitamin C concentration was highest in the fruit.
