Sweet corn is classified as a horticultural commodity that is very easily damaged. Damage quickly occurs after the harvest which causes a decrease in quality. The purpose of this study was to determine the effect of cooling temperature on shelf life and the physicochemical quality of sweet corn. The study used a Randomized Block Design (RBD) with cold storage temperature treatment namely: 1oC, 5oC, 9oC, and room temperature 27oC. Each treatment was repeated three times as a group. Sweet corn that has been stored is then observed: shelf life, weight loss, starch content, total dissolved solids, and reducing sugar content. The results showed that storage of sweet corn at 1oC was the best cooling temperature treatment based on decreasing weight loss, 2.68% lower, the longest shelf life of 80 days, total dissolved solids of 23.33 brix, higher reducing sugar content of 5.18 %, and the lowest starch content is 2.49%. This research concludes that the storage temperature of 1oC can extend the shelf life and physicochemical quality of sweet corn
