Zeolite, a designated food additive, is known to absorb radioactive cesium via its cation exchange ability. In this study, we investigated the effects of zeolite treatment on the removal of radioactive cesium from flesh of the pickled plum during the production process, and found that the concentration of radioactive cesium in the flesh was reduced by the addition of zeolite. Taking the concentration of radioactive cesium in the pickled plum in the absence of zeolite as 100%, that in the presence of 10% zeolite was 55%, and that in the presence of 20% zeolite was 54%. On the other hand, the concentration of radioactive cesium was 74% when 10% granulated zeolite was added. Furthermore, when processed with brine, the radioactive cesium concentration was reduced to 31% by adding 10% zeolite.
