vegetables are the glucosinolates (GS) and their hydrolyzed isothiocyanate products. Isothiocyanates are chemopreventive agents demonstrating anticarcinogenic activity in the human diet. Previously, research in our group showed that a 5-d exposure to only

. Mustard seed meal contains glucosinolates, which break down in soil to isothiocyanate in moist soil ( Borek and Morra, 2005 ; Brown et al., 1991 ; Vaughn and Berhow, 2005 ; Vaughn et al., 2006 ). Boydston et al. (2011) demonstrated that much of the
