In order to select potato clones for making cold chip, this study analyzed the glucose content, acrylamide content, and the correlation between the two properties after harvest, 4℃ and 8℃ low-temperature storage, and 20℃ heating treatment of 47 breeding clones and control cultivars 'Atlantic', 'Sumi', and 'Gui Valley'. In all of the control cultivars and 47 clones, glucose content was below 0.25% and acrylamide content was below 1000 ppb just after harvest, but after 4℃ low-temperature storage both the glucose content and acrylamide content increased rapidly and only 4 clones H7, H13, H16, and H40 showed a level below 500 ppb. In 8℃ low-temperature storage as well both contents increased, but the increase was relatively smaller than that in 4℃ low-temperature storage. In addition, 20℃ heating treatment decreased both contents. In the results of analyzing the correlation between glucose content and acrylamide content at low-temperature storage, a positive correlation was observed. In conclusion, clones H7, H13, H16, and H40 showing low glucose content even at low-temperature treatment were found to contain less acrylamide and therefore they were selected as potato clones suitable for making cold chip.
