Abstract : Mango fruits have a high production potential for sale in domestic and international markets. Mango fruits can be consumed while they still in the unripe stage, with a green peel color. In this study, 5 mango cultivars, 'Fha-Lan', 'Khaew Sawoey', 'Choke Anan', 'Thavai Duankao', and 'Nam Dokmai # 4', were used to investigate fruit qualities. The results showed that high contents of starch, fiber, protein and lipids were found in 'Khaew Sawoey' (300 g/kg DW), 'Nam Dokmai # 4' (45%), 'Fha-Lan' (0.078 g/100 gDW) and 'Choke Anan' (0.56 g/100 gDW), respectively. 'Fha-Lan' and 'Choke Anan' had similar levels of vitamin C content (40 mg/100 gFW). During storage at 13°C, 'Choke Anan' showed a slow ripening process and stem end rot disease occurrence when compared with other cultivars. Peel and pulp color and firmness slowly changed during storage. In addition, the total soluble solid content of 'Choke Anan' increased slowly when compared with other cultivars. Therefore, 'Choke Anan' is a cultivar with high potential for producing and exporting as unripe mango fruit. On the other hand, unripe 'Nam Dokmai # 4' was consumed as a healthy food because of its low starch and high fiber content. 'Nam Dokmai # 4' also showed the same high content of vitamin C as 'Fha-Lan'.
