Effect of Storage Atmospheres and Exposure Periods on the Incidence of Internal Breakdown and Physicochemical Changes of 'Carabao Mango (Mangifera indica L.) Fruits. Major Professor: Dr, Doroteo B, Mendoza, Jr. ‘Carabao' mango fruits stored under low oxygen atmospheres (2.7% to 7.7%) for 7 days or high CO combined with low O2 (18,5% CO2 4 2.5% Oy) for 4 to 7 days at ambient temperatures (26-32°C) exhibited internal breakdown. Fruits stored in 18.5% GO, 42.5% O, had more areas affected and with the severe type of disorder, High CO? with abundant Op (18.5% CO, / 20% Op) failed to initiate this disorder. Low O72 was associated with the occurrence of internal breakdown which was aggravated by high GO» and prolonged expoSure period. Anaerobic respiration appears to be the predominant process in the disposition of disorder as indicated by low oxygen uptake and high respiratory quotient during storage, This was further substantiated by the presence of fermented odor after ripening: Low oxygen (2.7% to 7.7%) atmosphere maintained respiration and ethylene production of stored fruits at low rates during storage, There were indications among fruits at these levels of O7 for failure to show the typical climacteric respiratory behaviour during and after storage for 4 and 7 days. Low ethylene production was also observed during storage at low oxygen. However, the rate and pattern was not consistent particularly upon transfer to air. . Anaerobic respiration which occurred during storage in those atmospheres further brought about low internal ethylene concentration, accumulation of organic acids, high pH, failure of starch hydrolysis and slower carotenogenesis. These abnormal chemical changes might have elicited the following features of internal breakdown: delineated starchy areas with or without air pockets formation, low sugar content, pale yellow pulp color and presence of fermented odor,
