저온 저장한 감자의 가공적성을 향상시키기 위한 일련의 실험으로 $0^{circ}C$, $5^{circ}C$및 $10^{circ}C$에서 감자(남작)를 3개월간 저장한 후 $20^{circ}C$에서 reconditioning을 행하면서 reconditioning기간에 따른 감자의 glucose, fructose 및 sucrose의 함량변화를 조사하였다. 이들 당류중 sucrose가 감자에 다량 함유되어 있었으며 reconditioning기간 경과에 따라 가장 신속하게 그 함량이 감소되었다. 저온 저장한 감자의 reconditioning기간과 환원당 함량의 관계는 지수함수 관계로 나타낼 수 었었으며. 감자의 basal부위가 apical 부위보다 장기간의 reconditioning기간이 소요되었는데 감자부위에 따른 환원당의 함량차이를 고려할때 $0^{circ}C$, $5^{circ}C$ 및 $10^{circ}C$에서 저장한 감자의 적정 reconditioning기간은 각각 9.4주, 5.6주 및 1.3주인 것으로 조사되었다.
To measure the optimum reconditioning period, potatoes stored at low temperatures ($0^{circ}C$, $5^{circ}C$ and $10^{circ}C$) for three months were reconditioned at $20^{circ}C$. Contents of glucose, fructose and sucrose of halved and whole potatoes were monitored during the course of storage and reconditioning. In halved potaotes basal portion contained higher amount of glucose, fructose and sucrose. The sugars in basal portion decreased more rapidly than those in apical portion, and sucrose disappeared fastest among the sugars in both portions during reconditioning period. The relationship between reducing sugar and reconditioning period could be presented as exponential equation. I consideration of uneven distribution of sugar contents between apical and basal portion, the required optimum reconditioning period at 20 could be 1.3 weeks, 5.6 weeks and 9.4 weeks for potatoes stored at $10^{circ}C$, $5^{circ}C$ and $0^{circ}C$, respectivery.
