American ginseng roots were treated with an antimicrobial agent, and stored under various CA (2,5, and 8% CO 2 ) or MA conditions to extend the shelf‐life. Changes in respiration rates during CA storage, gas composition in packages, saponin and free sugar content, and other quality factors were monitored during storage. The respiration rate of ginseng increased rapidly during the first month of high CO 2 CA storage and then slowly decreased to stable levels after 3 mo storage. In MA studies, the equilibrium CO 2 concentration was attained after 20 days. There were no noticeable changes in appearance, saponin content and free sugars after 3 mo CA (5% CO 2 ) storage and MA packages.
