Respiration rate, internal atmosphere, and ethanol and acetaldehyde accumulation in heat-treated mango fruit.

Mature green mango fruits (cv. Keitt) were heated with forced air at 46 deg C and 95-100% RH for 3 or 4 h or at 48 deg for 5 h. Respiration rate increased 3.5- and 5-fold during treatment at 46 deg and 48 deg , respectively. After cooling to 20 deg , CO2 production remained higher in heated than in control fruits for 4 days (46 deg ) and 6 days (48 deg ), and then fell below that of control fruits. Immediately after heat treatment, internal CO2 concentration increased to 9% (46 deg ) and 13% (48 deg ) and O2 concentration decreased to 11% (46 deg ) and 6% (48 deg ). Whereas O2 concentrations returned to control levels within 6 h after heat treatment, CO2 levels remained elevated. Acetaldehyde and ethanol concentrations increased after heat treatment at 46 deg and 48 deg and remained elevated 6 h after treatment in fruits treated at 48 deg for 5 h. It is concluded that heating mango fruits with hot forced air at 95-100% RH does not provide an acceptable quarantine treatment for Keitt mangoes beca

use it exacerbates the development of internal breakdown.
