HORSERADISH (Site not responding. Last check: 2007-10-25) |
 | | The reported life zone of horseradish is 5 to 19 degrees centigrade with an annual precipitation of 0.5 to 1.7 meters and a soil pH of 5.0 to 7.5 (4.1-31). |
 | | The intense pungency and aroma of horseradish is the result of isothiocyanates released from the glucosinolates sinigrin and 2-phenylethylglucosinolate by the naturally occurring enzyme myrosinase (6.4-103, 14.1-7). |
 | | Horseradish is generally recognized as safe for human consumption as a natural seasoning and flavoring (21 CFR section 182.10 [1982]). |
