Abstract


Japanese Horseradish (Wasabia japonica (Miq.) Matsumara or Eutrema wasabi (Siebold) Maxim.), is a vegetable species originated from Japan. The use of wasabi for food and health curing use has been known for years. At present, wasabi is grown in many other countries other than Japan across the world such as: New Zealand, Taiwan, South Korea, Izrael, Brasil, Thailand, Columbia, Canada, USA, Great Britain and China. The crop has never been cultivated commercially in Poland. The main aim of the experiment was to find out if the crop can be grown commercially in Poland. In the previous experiment, it was proved that it could be grown under polycarbonate cover in Poland. In this research, the chemical contents of roots produced in Poland and Japan were compared. Roots of wasabi produced under polycarbonate cover in Poland and the original Japanese wasabi roots were taken under chemical evaluation. They included measuring amount of dry matter, polyphenols, antioxidant potential, reducing substances, total proteins, starch and raw fiber. The roots produced in Poland had more dry matter and less total proteins and reducing substances than the Japanese ones. Starch and raw fiver contents were on the same level in the roots produced in both countries. The antioxidant potential and polyphenols in the Japanese roots were higher than in the Polish ones. In the climatic conditions of Poland, it was possible to produce wasabi roots under the polycarbonate cover with their chemical contents at least in part similar to original ones from Japan.
