quality of processed chip during storage of potato 'Atlantic' and 'Du Baek' which were represented in South Korea.
This study was focused on finding out the optimal concentrations of ethylene treatment for potato storage at 15℃
and relative humidity (RH) 90±5%. For respiration rate, ethylene production and weight loss, the ethylene treated
potatoes was higher than the control potatoes. The higher ethylene concentrations, the longer the storage period. It
showed that ‘Atlantic’ was less sensitive to ethylene treatment than ‘Du Baek’. Sprouting rate of 'Atlantic' control
group was 68.9%. On the other hand, Ethylene 50 μL/L treatment group was 53.3%. Sprouting rate of 'Du Baek'
was 72.2% for control group and 53.3% for ethylene 50 μL/L treatment group. There were differences between
cultivars. Sprouting rate showed ethylene 10 μL/L and 100 μL/L treatments were higher than ethylene 50 μL/L
treatment. The contents of sugar and starch were highly decreased in the ethylene treatments than the control, thereby
being not affected the chip processing browning. Hunter 'L' value was about 50 in 4 months after storage. There was
no difference between control group and ethylene treatment group duration in chip color. Lightness was likely much
darker in 'Du Baek' than in ‘Atlantic’.
