Chapter 17:
Postharvest Handling Fresh
The Chinese prefer dried while
root purchases. The Koreans however, have keen preference for
fresh root. During the relatively short time span in which ginseng
has been grown in the Northwest, a small unfolding fresh root
market has developed in the larger cities of Los Angeles, San
Francisco, Seattle and Vancouver, British Columbia. Thus far root
sales have been primarily between individual growers and buyers,
who then sell the root into their Korean community. Thus far sales
have been primarily confined to the West Coast. Large, fresh market
roots can return up to $20/lb. Field run fresh roots typically
return $11-$12/lb. (see Chapter
18: Enterprise Budget for how his affects the gross return
possible per acre).
Refrigerated
root storage
Bert van Dalfsen (bvandalfsen@galaxy.gov.bc.ca),
Agricultural Mechanization Engineer, with the British Columbia
Ministry of Agriculture, Fisheries, and Food in Abbotsford BC
has studied the effect of refrigerated cold storage on fresh ginseng
root quality. In replicated trials he has reported that ginseng
can be successfully stored for up to 6 weeks with high humidity
and temperatures between 32 and 35 F. After 4 weeks of refrigerated
storage the roots were still soft and pliable. After 6 weeks the
surface of the cold-stored roots began to shrink and wrinkle.
Air holes were noted inside the roots upon cross-sectioning them
for observation. Another important finding of the study was that
roots took up any odors in the refrigeration room itself. Ginseng
roots that took on un-pleasant odors had a low quality.
Advertising
fresh root
As for promoting the availability of fresh root for sale growers
have found that taking ads out in popular Korean magazines and
newspapers has been lucrative. It has also been useful to talk
with staff at local Korean churches. Certainly the development
of web page should help sales.
Besides the monetary incentives associated with fresh sales there are other advantages as well. Drying costs are reduced naturally, but probably not eliminated as a certain percentage of the roots will simply be terribly deformed or broken and thus un-suitable for fresh sales. Thus far there does not seem to be a market for sliced fresh roots. Long thin roots that would normally dry into long thin, low valued dried forms can still be sold for fresh.
Keeping roots under refrigerated conditions as outlined above can further extend the fresh market shipping window.
Disadvantages
of fresh
Roots suitable for fresh sales will have to free from any blemishes,
rusty root, and certainly any rot. As buyers will be looking for
size, growers will have to dig through alot of root in order to
find the largest ones. Roots that make the size determination
will probably have to be dried or used in a value-added enterprise.
