The fruit of five cultivars (Mudeung, Geumseong, Wolchul, Bokjo and Boeun) of jujube (Zyziphus jujuba) were analyzed to estimate free sugar and organic acid content in unripe and ripe jujube cultivars. Glucose, galactose, fructose and sucrose were the major sugar components of jujube. In this study, we observed that sucrose, glucose and fructose content increased during fruit ripening. The highest sucrose content of jujube fruit was 20.54g/100g in ripe Wolchul cultivar. The sweetness index, which plays important role of taste, was also calculated from the content of sucrose, glucose and fructose. The sweetness of jujube fruit increased with fruit growth and development. The highest sweetness of jujube fruit was 116.32 in ripe Geumseong cultivar. Main organic acid detected in jujube were citric acid, malic acid and fumaric acid. As the weight, diameter and soluble solids of Zyziphus jujuba fruit were increased with the progress of ripening, organic acids were also increased. The highest citric acid and malic acid content in jujube fruit were 14.64g/100g (Boeun, ripe) and 19.33g/100g (Geumseong, ripe), respectively.
