Asian pear is one of the popular fruits in Korea due to its sweetness and juiciness. However, the consumption of fresh Asian pear has been limited and its demand has not increased. To overcome these, new cultivars of Asian pears have been introduced; however, their properties have not been studied. Therefore, the objective of this study is to investigate the physicochemical characteristics of the new cultivars of Asian pears, Yeongsan, Mansu and Sinhwa. Mansu showed the lowest pH and soluble solid content of Yeongsan and Sinhwa were significantly higher than that of Mansu. Flesh and peel of Mansu were the highest in L* value, while flesh of Yeongsan and peel of Sinhwa were the highest in a* value and the lowest in b* value. In texture profile, Sinhwa were higher in the hardness of flesh than Mansu and was higher in the chewiness of flesh than Yeongsan and Mansu. In dietary fiber content, peel was higher in all cultivars than flesh. Mansu was the lowest in soluble dietary fiber of flesh, but there was no significant difference in insoluble dietary fiber among cultivars. In free sugar content, Flesh of Yeongsan was the highest fructose and galactose contents all the samples, while flesh of Mansu and Sinhwa were the highest in sucrose and glucose content at 4655.18 and 6380.03 mg/kg.Potassium was major mineral in the flesh of Yeongsan, Mansu and Sinhwa and minor minerals, Ca, Mg, Na, and P content were 3.46 mg/100g, 7.36 mg/100g, 2.03 mg/100g and 1.01 mg/100g. In conclusion, the physicochemical characterization of the new pear cultivars is worth noting for further processing. However, it would be needed that the physiological functionality of the new cultivars is analyzed in the future to increase utilization of the pears.
