Abstract
This study was conducted to investigate the nutrient components and physicochemical properties of 23 Korean potato cultivars. Proximate composition, free sugars, organic acids, and free amino acids were analyzed, and water binding capacity, oil absorption, and Hunter color values were measured in this study. The content of crude protein was the highest in Seohong and the lowest in Jayoung cultivars. Crude ash content of Chugang was higher than that of other cultivars. Sucrose content was the highest among the free sugars, followed by glucose, and then fructose. The major organic acids in all potato cultivars were oxalic acid, citric acid, malic acid, succinic acid, and fumaric acid. The essential amino acid and non-essential amino acid contents in the 23 potato cultivars ranged from 60.33 to 550.91 μmol/100g and 300.44 to 1,098.58 μmol/100 g, respectively. The water binding capacity of Deiima and the oil absorption of Jasim cultivars were the highest values among the tested potato cultivars. The oil absorption of Gawon and Shinnamjak was greater than those of the other cultivars. From the results, Gawon and Shinnamjak cultivars could be suggested as beneficial for controlling fat intake.
