Abstract


Potatoes can’t be stored in very low temperature conditions that it is way Chlorpropham has grown in popularity as a sprout suppressant for long term storage of potatoes. The residue level of Chlorpropham in Christian and Roclas potatoes varieties, before and after washing, was analyzed using LC/MS/MS. The samples were extracted in an easy 3 step method using ethyl acetate. 0.27 mg/kg Chlorpropham residue was found in Roclas and 0.23 mg/kg in Christian. There was a decrease in the Chlorpropham concentration in the whole potato by 30.43-37.04 %. There was no significant difference between the 2 potatoes varieties, Christian and Roclas, in the % in which Chlorpropham residue was reduce after washing. Results indicated that the washing operation significantly reduces the Chlorpropham residue level in potatoes
