Abstract
Sweet corn with husk (Zea mays L. var. saccharata f. Peter corn) was stored at 5°C for 4 d under a photosynthetic photon flux density (PPFD) of l μmol m-2s-1 using red and blue LEDs. During storage， the sugar content (Brix) was measured consecutively for 4 d， and the amino acid content was analyzed after 4 d storage. Corn stored under blue LED light at 5°C had higher sugar content than corn stored in a dark， cool condition. Similarly， the content of umami was increased by storage under the blue LED-cool condition，a r esult likely due to increases in aspartic acid and the major amino acid， glutamic acid. The red LED-cool condition was not as good as the blue LED-cool condition for preserving corn， but was much better than dark， room temperature storage. In contrast， the palatability of sweet corn kept at room temperature in the dark quickly declined. Blue LED-cool preservation appears to be a useful technique for storing sweet corn with husk.
