To investigate the effects of its packaging and packaging environments on the quality of washed fresh ginseng, the ginseng was put into a polypropylene tray and tightly sealed with a 0.035-mm thick OPP film (OPP-1, normal air in package; OPP-2, 50% air replaced with N2; and OPP-3, 100% N2), packaged with a 0.08-mm thick PE film (CN-PE) or vacuum packaged with a 0.1-mm thick Ny + PE film (Ny+PE-Vac). After that, it was stored at 0°C for 10 weeks so as to determine changes in the quality. It was found that, the CO2 levels in OPP-2 and OPP-3 packages increased more than in OPP-1 and CN-PE during storage. During the storage, there was no significant difference in the moisture content and firmness of the treated fresh ginseng. The content of soluble solids content was initially 19.0 °Brix and increased as the storage period elapsed till it reached 19.5-25.3 °Brix in 10 weeks, and it least changed in Ny+PE-Vac and OPP-3 of all the treated ginsengs. A change in microbial population was relatively less in OPP-3 and Ny+PE-Vac and the sensory quality of ginseng in OPP-2 and OPP-3 was the best during storage.
