I have a question. I have some skin markings on Brazilian Kent mango which arrived on a container with a closed vent. I am wondering if it is CO2 injury? (M.O.)
Exposure of mangoes to below 2% O2 and/or above 8% CO2 may induce skin discoloration, grayish flesh color, and off-flavor development. If the closed vent resulted in carbon dioxide levels above 8%, damage to the mangoes may occur. However, it is important to note that skin markings can result from chilling injury (exposure to temperatures below 55°F) or other factors.
