Abstract
Contents of free sugars and sorbitol and their distributional profiles in Tsugaru, Fuji, Jonathan (Hong-Ok), and New Jonagold (Sin-Heung) apple cultivars were evaluated. Average total sugar contents of Tsugaru, Fuji, Jonathan, and New Jonagold were 9.62, 11.79, 11.20, and 10.28%, respectively. HPLC results showed sucrose, glucose, fructose, and sorbitol contents of apples ranged 0.72-3.26, 1.81-3.16, 5.08-6.96, and 0.22-0.96%, respectively. Ratios of individual sugar and sorbitol to sum of fructose, glucose, sucrose, and sorbitol (TS+S) were estimated for all apples. Fructose/TS+S and glucose/TS+S ratios did not differ significantly among cultivars, whereas sucrose/TS+S and sorbitol/TS+S ratios varied. Fructose/glucose ratios were 2.295, 2.244, 2.161, and 2.393 for Tsugaru, Fuji, Jonathan, and New Jonagold, respectively.
