Several citrus and subtropical fruits (oranges, limes, lemons, mangos and papayas) were evaluated for phytotoxicity to acetaldehyde vapor. Exposure of fruits to 0.5 or 1% acetaldehyde vapor for 24 hr (low concentration-long exposure) did not produce skin injury or off-flavor in comparison with non-exposed fruits. This non-phytotoxic effect was also obtained at 5 to 20% acetaldehyde vapor for 10 to 15 min (high concentration-short exposure). However, acetaldehyde vapor concentration of 4% for 1 hr or 5% for 30 min (high concentration-long exposure) produced severe lenticel and skin injuries to the fruits. Exposure of fruits at these concentration also produced lack of or off-flavor. Phytotoxicity of fruits to acetaldhyde vapor was a function of concentration and exposure.
