The invention relates to a pretreatment method for raising sulforaphane hydrolysis yield of broccoli seeds. According to the method provided by the invention, broccoli seeds undergo physical pressing to raise cell disruption degree and help a precursor substance glucophanin (GRA for short) of sulforaphane (SFA for short) generated by hydrolysis to be fully dissolved out. Solid residues are recovered after removal of grease. During the removal process of grease, ESP protein which commonly exists in broccoli and can convert GRA to sulforaphane nitrile without antitumor activity through catalysis can be deactivated. At a specific pH value, oil residues left after enzyme deactivation are added into a myrosinase solution which contains no ESP enzyme so as to greatly raise conversion rate of SFA generated through GRA hydrolysis. In comparison with old-fashioned broccoli sulforaphane enzymolysis treatments, the method provided by the invention is simple, has advantages of low loss of GRA during ...
