Sinalbin

• White or yellow mustard, Sinapis alba or Brassica hirta, is a European native with large pale seeds and a different defensive storage compound, sinalbin. ❋ Harold McGee (2004)

These substances may be natural constituents of the seeds, such as gossypol and cylopropenoid fatty acids in cottonseed, cyanogenetic glycoside in linseed, ricin in castor beans, sinigrin or sinalbin in mustard seed, saponin in shea nuts, the trypsin inhibitor in soyabeans, or toxic mould metabolites, such as aflatoxin, which may form if the seeds are allowed to spoil by moulds. ❋ Unknown (1995)

Agricultural Research Service studies suggest sinalbin and other compounds released into soil by applications of white mustard seed meals can kill or suppress certain weedy grasses and annual broadleaf weeds. ❋ Unknown (2009)

The irritating portion of sinalbin is much less volatile than the irritant in sinigrin, so little of white mustard’s pungency rises into the nose. ❋ Harold McGee (2004)
