-Eutrema japonica (Miq.) Koidz. - syn. Wasabia japonica (Miq.) Matsum.; Eutrema wasabi Maxim.; Cochlearia wasabi Siebold - Brassicaceae \\
-Japanese horseradish, **Japanischer Meerrettich**, Wasabi
-Perennial herb, up to 60cm tall, native to Japan, Korea, Sakhalin, cultivated in Japan, Korea and Taiwan for its edible rhizomes (source of the pungent condiment, wasabi). \\

-" Its stem is used as a condiment and has an extremely strong flavor. Its hotness is more akin to that of a hot mustard than that of the capsaicin in a chili pepper, producing vapours that stimulate the nasal passages more than the tongue." [[http://en.wikipedia.org/wiki/Wasabi]]
-The rhizome contains most of the flavour and is the part most widely used, although both the leaves and petioles contain some of the flavour. Wasabi myrosinase liberates a mixture of isothiocyanates from precursor molecules, giving wasabi its distinctive flavour. \\

-The main volatile components of E.wasabi grown in Yunnan were identified as 1,6-hexane diisothiocyanate (30.7%) and allyl isothiocyanate (17.1%)  with GC-MS. \\

-Total isothiocyanates content of Japanese horseradish rhizome grown in New Zealand was 2067mg/kg fresh weight, with allyl isothiocyanate (AITC, 1937 mg/kg) as the main component. Minor components present were 3-butenyl isothiocyanate (43 mg/kg), 3-pentenyl isothiocyanate (47 mg/kg), sec-butyl isothiocyanate (18 mg/kg), isopropyl isothiocyanate (12 mg/kg) and 5-hexenyl isothiocyanate (7 mg/kg). \\
