The fresh ginseng roots were stored in modified atmosphere system with a nitrogen generator to validate the effect of exchanges by N sub(2) at interval on the qualities of ginseng in active modified atmosphere packaging (MAP). The effect of low 0 sub(2) on the chemical compositions was also determined. The storage life of fresh ginseng could be extended about 150 days in active MAP. Quality analysis showed that higher freshness and better quality of fresh ginseng were obtained from 0.07mm and 0.05mm packages with lower decay after 150 days of storage, especially in 0.07mm package. The firmness of stored ginseng was almost the same as that of harvested ginseng. The chemical compositions in fresh ginseng was also not changed much, especially the content of total saponin. It indicated that fresh ginseng could be stored successfully for 150 days without losing much of its quality and chemical compositions with lower weight loss in active MAP by N sub(2) generator.
