EFFECT OF STORAGE TEMPERATURES ON RIPENING BEHAVIOR AND QUALITY CHANGE OF VIETNAMESE MANGO CV. CAT HOA LOC

Vietnamese mango fruits cv. Cat Hoa Loc (Mangifera indica L.) were harvested at 75-84 days after fruit set and held at seven different temperatures from 8±10C to 24±10C and at ambient temperature for storage. Variation on quality of mango fruits cv. Cat Hoa Loc in low temperature were less than compared with these in ambient temperature (29-330C). Evaluation for quality attributes and storage life of each storage temperature were investigated to find out the limitation for mango stored at various temperatures. Changes in ripening behavior expressed as skin colour, fruit firmness and chemical properties of the fruit stored at 20 and 240C were equal to the fruits stored at ambient temperature. Lower storage temperatures could extend storage life over high storage temperatures. The result of this study showed that the fruits could not be stored at 11 and 80C for a long period because the fruits developed chilling injury symptoms and uneven ripening. The suitable storage temperature for Cat Hoa Loc mangos that could extend storage life to about 19 days without chilling injury was 140C. The fruit losses of each storage temperature and cause of the end of storage life were also obtained and discussed in this study.
