The effect was studied of solvent extraction with absolute or 95% methanol with or without 10% ammonia and hexane, of low‐molecular weight carbohydrates from rapeseed, canola and mustard seed. Rape‐seed of Midas and Hu You 9 (Chinese) varieties, cariola (low glucosinolate, low erucic acid rapeseed) of Triton cultivar and Domo mustard seed were studied. Soluble sugar of hexane‐extracted meals was 6.17 to 7.56%. Sucrose and stachyose were major sugars, and raffinose was in smaller amounts. Extraction of rapeseed and mustard seed with ammonia (10% w/w) with absolute or 95% (v/v) methanol reduced soluble sugars by up to 82%; sucrose and raffinose were extracted more efficiently than stachyose. The total soluble flatulence‐causing sugars was lowered by up to 69%.
