Hot water immersion quarantine treatment system for lychee and longan. p. 31-36, In Proceedings of the 12th International Tropical Fruit Conference, Kona, Hawaii, 2002. Interpretive Summary: A commercial-scale hot water immersion unit was constructed and installed at Kahili Farms on Kauai. The unit will be used to treat lychee and longan for export from Hawaii to the U.S. mainland. The hot water immersion treatment controls fruit fly and other quarantine pests in these fruits. Hot water treatment results in significant quality loss in lychee but not in longan. Technical Abstract: A commercial-scale hot water immersion unit was constructed and installed at Kahili Farms on Kauai. The unit will be used to treat lychee and longan for export from Hawaii to the U.S. mainland. The hot water immersion treatment of 49oC for 20 min controls fruit fly and other quarantine pests in these fruits. Hot water treatment results in significant quality loss in lychee but not in longan. This hot water immersion unit will give growers an alternative quarantine treatment to export fruits from Hawaii. Fruit treated by hot water immersion will be permitted to carry an "organically grown" label unlike irradiated fruit, giving growers the option to distribute fruit through organic produce markets and retailers as yet reluctant to sell irradiated produce. |
