抄録

This study was undertaken to reveal the changes in various saccharides contents of sweet corn during storage, and to relate them to the changes of respiratory rate. Sweet corn (cv. Golden Cross Bantam) grown on Shinshu University experimental farm was harvested at the standard harvest maturity 20 day after silking, and immediately stored for 8 days. The changes in composition and content of sugars and polysaccharides were examined throughout the storage periods. (1) Decrease in sucrose content of kernels was already found whithin 3 hours after harvested at 25°C and the content was reduced to one-half the initial amount after 24 hours, whereas the content of those stored at 5°C decreased gradually reaching to one-half after 7 days. Maltose and stachyose which were not detected at harvest appeared after 6 hours of storage at both temperatures and existed through the whole storage periods. (2) Among polysaccharides, phytoglycogen was found more abundantly than starch. The phytoglycogen content increased gradually during storage at 30°C, whereas no marked chang was observed at 2°C. It was assumed that the rapid decrease of sucrose during storage was due to the conversion to polysaccharides, especially starch, as well as to consumption by respiration. (3) Carbon dioxide production of sweet corn on the cob was higher with rise of storage temperature and rapidly decreased especially during early period of storage.
