Abstract:
Mango is a tropical climacteric fruit produced in most parts of Ethiopia. It reaches its
respiration and ethylene peak during the ripening process due to weather conditions, diseases,
lack of proper management, and inadequate storage time. Because of its highly perishable
nature, postharvest losses account for 41% of the total loss. However, these losses depend on
the cultivar and post-harvest management practices. One widely practiced post-harvest
management technique is the application of chitosan-based edible coatings on the fruit. This
experiment was initiated to evaluate the performance of chitosan concentration on different
mango cultivar's fruit quality parameters and shelf life. Therefore, the experiment was
conducted at University of Gondar Horticulture Laboratory using three mango cultivars
(Local, Tommy Atkin and Kent) and four-chitosan concentration (0, 1, 2 and 3% v/v)
treatments with three replication in a completely randomized design. The physical and
chemical characteristics of fruits were examined at seven days intervals during the
experiment. Then, their mean values were analyzed by SAS software version 9.4, and the least
significant difference at a 5% significance level was used to determine significant differences
between treatment means. Based on the analysis of variance result, all physical and chemical
quality parameters were significantly (p<0.05) affected by both chitosan concentration and
