摘要：The two 2-TBA methods, Jacobson and Kirkpatrick's with the use of purified n-propanol and YuSinhuber's without the use of an organic solvent, were compared for effects of irradiation doses on the press juices of both control and irradiated samples; the former method did not show an labsorbance near 530mμ but the latter showed maxima at both 430 and 530mμ. The method of Jordan and Veatch for determination of carbonyl compounds was also examined on the press juice but no sharp maximum was observed. Relations between the off odor induced by irradiation as well as the detection of deterioration on storage and absorbances at 430 and 530mμ, by Yu-Sinhuber's method, were also studied but no definite relation between the absorbances and the off odor and deterioration could be found. The 2-TBA method and alcoholic alkaline titration method were also compared for the detection of deterioration during the storage of the control sample; the latter method appeared to be more reliable at the present time.
