QUALITY CHANGES OF FRESH-CUT 'MAHACHANOK' MANGO AT DIFFERENT STORAGE TEMPERATURES

‘Mahachanok’ mango is very popular in domestic and export markets of Thailand. After fresh-cut processing, produce quality deteriorates quickly due to tissue darkening, development of glassy appearance, surface desiccation and loss of firmness. Very little is known about the marketable period of the fresh-cut produce. In this study, fruit were peeled, flesh removed from the seed, and then stored at 4, 7, 10 and 25°C. Results showed that 4 and 7°C storage prolonged shelf life for six days while at 10 and 25°C, shelf life was only four days and one day, respectively. Color as hue values was best maintained at 7°C whereas it declined most rapidly at 25°C. Total sugar content and firmness did not significantly differ with treatment. Titratable acidity decreased with storage at a lower rate at 7°C than at 25, 10 and 4°C.
