Respiration, pectolytic activity and textural changes in ripening African mango (Irvingia gabonensis) fruits.

Postharvest changes in fruit firmness, respiration rate, fruit colour and pectinesterase and polygalacturonase activities were studied in commercially mature, hard green I. gabonensis fruits during storage under tropical ambient conditions (28 plus or minus 1 deg C and 68 plus or minus 2% RH). Respiration showed a climacteric pattern attaining a peak of 99.37 ml CO2 kg-1 h-1 on Day 5 of storage, while full ripeness was attained on Day 10. Pectinesterase and polygalacturonase activities increased with fruit ripening. Fruit firmness decreased as pectolytic activity increased with a reduction in deformation force from 49 kPa in unripe fruits to 25 kPa at the edible ripe stage.
