Phytotoxicity of citrus and subtropical fruits to acetaldehyde vapor
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.
