Abstract
While the importance of domestic agriculture is stressed, Japan's imports of agricultural products are increasing year by year. From the standpoint of public health, what matters most is pesticide residues in imported agricultural products, in particular, the residues of chemicals applied after harvest for long-distance transport and long-term conservation.
Recentv, we have completed a simultaneous analytical method to detect two sprout inhibitors-maleic hydrazide and chlorpropham-in potato chips. The recovery rates and detection limits of maleic hydrazide and chlorpropham by this method were worked out at 81±5, 79±4%, 0.1, 0.01μg/g-raw, respectively.
A residue survey was carried out in potato chips on the market. The detection rate of maleic hydrazide was 25% with the maximum amount of 0.3μg/g-raw. The detection rate of chlorpropham was 45% with the maximum amount of 0.11μg/g-raw.
