Abstract: Problem statement: Mango is a tropical fruit that ripens very quickly; for this reason, there
has been a continuous effort to develop postharvest technologies to extend its shelf life and quality.
Among them, 1-Methylcyclopropene (1-MCP) is widely used because it inhibits the action of ethylene
receptors. Approach: Changes in physicochemical parameters, bioactive compounds and cell wall
degrading activities were evaluated during storage and ripening of fresh whole mangoes treated with 1-
MCP (750 nL L-1). Mature-green mangoes, cultivar Kent, untreated or treated with 1-MCP were
evaluated for external quality, phytochemicals, Polygalacturonase (PG) and Pectin Methylesterase
(PME) enzymatic activities during storage at 20°C for 2 weeks. Results: Concentration of ascorbic
acid decreased during fruit ripening but 1-MCP-treated mangoes had reduced losses.
Polygalacturonase and pectin methylesterase activities were reduced in the treated fruits as compared
to untreated mangoes. Small changes in b-carotene were observed between treated and untreated fruits.
Conclusion: 1-MCP affected the ripening process in “Kent” mango, reducing losses of ascorbic acid,
this treatment is justified since it helps to maintain mango’s nutritional value during its shelf life.
