In this study, the changes that occurred in the quality of minimally processed sliced Deodeok (Codonopsis lanceolata) in relation to the packing method during storage at 7℃were investigated. The storage tests were conducted for seven days using PE sealing, but PP sealing and vacuum packaging preserved the Deodeok for 14 days. On the seventh day, the vinyl-packaged Deodeok showed a remarkable fall in quality with 4.5 °Brix, but the PP-sealed and vacuum-packaged Deodeok showed slight falls with 6.4 and 6.8 °Brix, respectively. The PE- and PP-sealed Deodeok did not show significant differences in texture and moisture content for two days, and the moisture content was highest in the vacuum-packaged Deodeok during storage. In relation to the total viable cell and the coliform count, the vacuum-packaged Deodeok showed the lowest rate of increment during storage, followed by the others. Thus, the bubble-washed and vacuum-packaged minimally processed sliced Deodeok was found to have the best quality.

There is increasing interest in freshly cut products, that is, foods produced without washing and cutting. In this study, the quality of freshly cut sliced Deodeok was compared with that of what based on its washing methods. In bubble washing, the Deodeok rises to the water surface apace and is broken into centimeter sizes. Microbubble washing calls for the production of a great number of 0.1 mm-sized bubbles in anions-bearing water and their passing through a trumpet-shaped hole at a high pressure. To compare the product deterioration rates of the specimens, they were stored at 10℃ for 10 days. In the specimens washed with the control method and with hand washing, the deterioration rate was 80%; and in the specimens washed with bubble and microbubble washing, 20~30%. The L-value (an index of browning) was higher in the bubble and microbubble washing than in the control and the hand washing, which implies that browning was minimized during the storage. As for the viable cell and coliform group counts that were measured during the storage, the specimens washed with the control method showed the highest values. In contrast, the specimens washed with microbubble washing showed the lowest values. In the sensory test, the specimens washed with microbubble were highest in storage preference. In conclusion, the Deodeok that was stored after it was washed with microbubble washing was found to have had the best quality.

We preprocessed and pickled Deodeok with Doenjang to improve its preservability and to distribute it widely, and we stored Deodeok for 3 weeks at $7^{\circ}C$ and measured its quality. The sample pre-treated with 20% of dextrin retained its early texture better than the samples pre-treated with other methods after 3 weeks of storage (p<0.05). The samples pre-treated with other controls showed propagation of microorganisms; but Doenjang pre-treated with 20% of dextrin or sugar showed less increase in the water content. The microorganisms count in samples pre-treated with other controls was 4.0 log CFU/g after 3 weeks of storage, but the microorganisms count in the sample pre-treated with 20% of dextrin was 2.2 log CFU/g; in other words, the propagation of microorganisms was minimized in the sample pre-treated with 20% of dextrin (p<0.05). In the investigation of the preferences, this D-20 sample showed maximum improvement in color, smell, taste, and other general preferences factors. Thus, the best processing method for the optimal quality maintenance of Deodeok is to sugarize it with 20% of dextrin before pickling with Doenjang. The product prepared using with this process can be preserved for 3 weeks at $37^{\circ}C$; that is, this product is expected to have a refrigerator shelf life of 3 months. 더덕을 전처리하여 된장절임을 함으로써 저장성을 높여 폭넓게 유통시키기 위해 $37^{\circ}C$에서 저장하면서 품질을 측정하였다. 조직감은 저장 3주 후 D-20 처리구의 변화가 초기에 비해 7.6%의 감소율로 다른 처리구보다 유의적으로 가장 잘 유지되었으며(p<0.05), 수분함량의 경우 정제수(CT) 처리구는 65.1%로 다른 처리구보다 된장의 수분함량이 높아 저장 중 미생물 번식에 영향을 주었지만 S-20 처리구는 56.2%, D-20 처리구의 경우 53.8%로 저장 중 된장의 수분이 감소되는 것으로 나타났다. 더덕의 색 변화의 경우 저장 3주 후 D-20 처리구 된장의 L값은 각각 37.5 value, b값은 15.0 value로 다른 처리구들에 비하여 변화가 가장 적었으며, 미생물의 경우도 CT는 log 4.0 CFU/g이었던 반면, D-20 처리구는 log 2.2 CFU/g으로 나타남에 따라 다른 처리구보다 저장 중 미생물 번식이 가장 최소화되어진 것으로 나타났다(p<0.05). 기호도 조사 또한 D-20처리구가 색, 향미, 조직감, 맛, 씹힘성의 모든 항목에서 가장 높은 평가를 받았다. 따라서 더덕을 덱스트린 20%로 절임한 후 된장절임을 하였을 때 저장 중 품질유지에 가장 좋은 처리 방법으로 나타났으며, $37^{\circ}C$에서 3주까지 저장이 가능한 것으로 나타나 냉장 유통 시 3개월까지 가능한 것으로 판단된다.
