Effect of Surface Washing Treatment on Quality of Fresh Ginseng during Storage

표면세척이 수삼의 저장 중 품질에 미치는 영향

  • Published : 2007.08.31


This study was basic research to improve the existing method far distributing just harvested and sail-clad fresh ginseng. The quality of surface-washed fresh ginseng was compared to that of muddy fresh ginseng during storage at 0, 5, 10, and $20^{\circ}C$. After 45 days of storage, there was no difference in weight loss between the washed ginseng and the control at $0^{\circ}C$, but the loss was 46% and 37% lower in the washed than the control at $5^{\circ}C$ and $10^{\circ}C$, respectively. The ginseng stored at $20^{\circ}C$ after washing had less deterioration than the control stored at $10^{\circ}C$ for the same period. The sensory characteristics of the washed ginseng showed better quality scores ranging from 6.8 to 8.2, while the control ranged from 5.7 to 6.9 after 45 days of storage at $10^{\circ}C$. The washed ginseng had less viable cells, mold and yeast, and coliforms at 0.87, 1.55, and 0.95 log units, respectively, compared to the control, and this trend was maintained in the washed ginseng throughout storage.
