Summary
Potatoes with an applied load of 196 N (20 kgf) were stored at 7°C for 60 days. The sugar contents (glucose, fructose and sucrose), invertase, UDP-glucose pyrophosphorylase (UGPase) and sucrose 6-phosphate synthase (SPS) of the potatoes were measured at intervals during storage. The aim of this study was to determine whether static loading affects the sugar contents and enzymes levels in potatoes during storage. Static loading increased the glucose, fructose and reducing sugar contents, as well as the invertase activity of potatoes during storage. The reducing sugar content of static loaded potatoes was correlated (P<0.01) with the invertase activity.
