Spring-season lance Asia bell (Codonopsis lanceolata Benth. et Hook.) roots harvested in late May were stored under air, controlled atmosphere (CA) and modified atmosphere (MA) conditions at 0 deg C, and their quality changes during storage and marketing period were investigated. During 2 months of storage, high weight loss occurred in air storage, especially in direct-blowing refrigeration chamber system (DBRS) which simulated commercial-scale cold storage. In DBRS, high weight loss resulted in severe shrinkage. CA and MA storage effectively reduced weight loss and the incidence of shrinkage. Flesh softening was also reduced by CA and MA storage except for remarkably low incidence of flesh softening observed in the roots stored for one month in DBRS. The flesh firmness tended to be higher in CA stored roots after one month storage. In contrast, after two months of storage, no clear differences in the firmness were observed among treatments. No positive effects of CA and MA storage on the surfac

e colour of peeled roots were observed immediately after removal from the storage. During the marketing of peeled roots, however, CA- and MA-stored roots tended to have longer shelf-life showing less surface discoloration and flesh softening. Considering the root quality during long-term storage and poststorage processing potential, CA of low oxygen combined with high carbon dioxide appeared to be an effective storage method.
