Abstract
This study considered the effect of type of Ultraviolet (UV) light on quality of baby corn during distribution. Baby corn were packed on polyvinyl chloride (PVC) trays in the amount of 100 gram/tray. They were put in low density polyethylene (LDPE) bags and were then placed on the shelf at 5 oC under different conditions of UV exposure at 2 kJ/m2 for 5 minutes per day. The sample was experimented under four different conditions: 1) no UV exposure (control), 2) UV-A exposure (UV-A), 3) UV-B exposure (UV-B), and 4) UV-C exposure (UV-C). All treatments were exposed to fluorescent lights for 12 hours per day for simulating shelf life conditions. The results of experiment showed that Baby corn exposed UV of all treatments had higher score on firmness, lightness (L*), yellow color (b*), vitamin C content and total carotenoids than baby corn of control treatment during distribution period of 28 days. Thus, the experiment results indicated that UV could maintain quality and prolong shelf life of baby corn.
