Shelf-life extension of American fresh ginseng by controlled atmosphere storage and modified atmosphere packaging
1999
Jeon, B.S. | Lee, C.Y.
American ginseng roots were treated with an antimicrobial agent, and stored under various CA (2, 5, and 8% CO2) 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 CO2 CA storage and then slowly decreased to stable levels after 3 mo storage. In MA studies, the equilibrium CO2 concentration was attained after 20 days. There were no noticeable changes in appearance, saponin content and free sugars after 3 mo CA (5% CO2) storage and MA packages.
