Abstract

The effect of a modified packaging design on the cooling time of 'Carabao' mango fruits, with and without modified atmosphere packaging (MAP) was determined. The original design of the divider currently used in export cartons was modified by placing holes with diameter of 2.54cm on each cell partition. Two trials were conducted, with four treatments having three replicates each. The temperature of the fruit pulp was measured, and the physical characteristics and fruit quality were determined. Using the temperature data, the cooling coefficient (k) and half-cooling time(Z) were calculated . In the first trial, the calculated k values were -0.089hr⁻¹ (TI),-(TI), -0.058hr⁻¹ (T2),-0.148hr⁻¹ (T3) and -0.047hr⁻¹ (T4) and Z values were 7.79 hours (TI), 11.95 hours (T2), 4.68 hours (T3) and 14.75 hours (T4). In the second trial, the calculated k values were -0.525hr⁻¹ (TI),-0.19hr⁻¹ (T2),-0.732hr⁻¹ (T3) and-0.269hr⁻¹ (T4) and Z values were 7.79 hours (TI), 11.95 hours (2), 4.68 hours (T3) and 14.75 hours (T4). The use of a modified divider without MAP reduced half-cooling time of mango fruits by 41.2% and with MAP by 33.8%
