ON THE MANGO CA STORAGE AND TRANSPORTATION FROM SUBTROPICAL TO TEMPERATE REGIONS IN JAPAN |

| Abstract:
This study aims at technological establishment of CA storage and long-distance transportation for tropical fruits. 660 kg of mangoes (Irwin) were transported by 2-ton refrigerator van under 12°C on a car ferryboat, from Okinawa Islands to Tokyo Port, from Tokyo to Tsukuba University by land. It took 4 days. After that, the van was remade into a CA storage chamber. The gas composition of O2/N2/CO2 in the chamber was adjusted to 5/90/5%. Ethylene that comes out of the fruits was obsorbed and decomposed with activated charcoal/vanadium oxide catalyst. The following results were obtained: 1. In the quality evaluation of mango fruits, the hardness of the surface significantly related with the ratio of sugar to acidity. 2. A month-long CA storage was possible. The following technological problems of transportation and storage were examined; 1) Gas composition of O2/N2/CO2 in the fruit tissue was 20/78/2%. 2) The rate of ethylene gas generation was exponentially proportioned to the increase of mango fruits ripening grade. 3) By chilling injury test, minimum temperature in the CA storage could be lowered to 8 ±0.5°C. | |
