Background : Platycodon grandiflorum has been used as famous medicinal vegetable and traditional medicine in Korea. Platycodon grandiflorum is used more for vegetable than it is used as a medicine. Proper storage conditons are required for distribution of Platycodon grandiflorum as vegetables. The purpose of this study was to find the appropriate storage temperature.
Methods and Results : 2-years old Platycodon grandiflorum cultivated in Herbal Crop Research, RDA Eumseong was used. They were packed with plastic container box of 45 × 70 × 30 ㎝ and then stored at –2℃, 2℃, 5℃, 25℃, humidity 80 - 82%. During the storage, hardness, L a b values, weight loss, decay rate were measured every 30 days as quality indices. During the storage period, L value decreased but a and b values increased and same pattern was observed at all storage temperatures. Hardness decreased and same pattern was also observed at all storage temperature. Under constant humidity conditions, weight loss was larger at higher temperature. The higher the temperature, the larger the deviation at weight loss. There were little decay but 25℃ temperature stored showed that dacay rate was higher with time over.
Conclusion : The favorable temperature for storage is –2℃ - 2℃ while maintaining constant humidity.
