Impact of atmosphere, organic acids, and calcium on quality of fresh-cut 'Kensington' mango

Fresh-cut slices from ripe 'Kensington' mango (Mangifera indica L.) were prepared aseptically and stored under various treatments at 3 degrees C. Treatments included reduced oxygen (2.5%), enhanced carbon dioxide (5-40%), organic acid application, calcium chloride application, and combinations of the above. Symptoms limiting shelf-life were characterised by tissue darkening, development of a 'glassy' appearance, surface desiccation, and loss of firmness. Reduced oxygen (2.5%) was effective at controlling tissue darkening and the development of a 'glassy' appearance, while calcium application (3%) was partly effective at controlling darkening. Calcium chloride however significantly slowed (but did not stop) loss of tissue firmness. Carbon dioxide (5-40%) and citric acid had little positive effect on shelf-life, with both treatments appearing to promote tissue softening. A combination of low oxygen and calcium allowed 'Kensington' slices to be held for at least 15 days at 3 degrees C. (C) 2006 Elsevier B.V All rights reserved.
