In addition to extraction of the glucosinolates from RSM as a means of overcoming their toxicity, many investigators have attempted chemical alternation of the glucosinolates to destroy or remove the toxic compounds. Some have added unheated crushed rapeseed to the meal to provide a source of myrosinase, so as to autolyse the glucosinolates and liberate isothiocyanates, which are then steam volatilised. This is only partially successful since most of the isothiocyanates formed in rapeseed meal are not sufficiently volatile to flash off. Others have tried ammonia treatment and heat, cooking with soda under pressure, or treatment with ferrous salts and distillation.  3, record 1, English, - isothiocyanate

On extrait donc les glucosinolates des tourteaux de colza pour leur enlever leur toxicité, mais bon nombre de chercheurs ont également essayé de les modifier chimiquement pour détruire ou éliminer les composés toxiques. Certains ont ajouté aux tourteaux du colza broyé non chauffé comme source de myrosinase, afin de provoquer une autolyse des glucosinolates et de libérer des isothiocyanates qui peuvent être volatilisés par la vapeur. Ce procédé ne réussit pas parfaitement, parce que la plus grande partie des isothiocyanates formés dans les tourteaux de colza ne sont pas suffisamment volatils. D'autres ont essayé un traitement par l'ammoniac et la chaleur, une cuisson sous pression avec de la soude, ou un traitement avec des sels ferreux suivi d'une distillation.  2, record 1, French, - isothiocyanate

Glucosinolates are extracted from ground full-fat canola seed using boiling water. The aqueous extract is passed through weak anion exchange resin, which binds glucosinolates. Myrosinase is applied. Hydrolyzed glucose eluted from the column is analysed and quantified by a glucose oxidase/peroxidase assay. Recovery of sinigrin directly loaded to the ion exchange column was 91% independent of initial concentrations ranging from 2-30 µmol.  2, record 2, English, - sinigrin

In canola or rapeseed, the enzyme myrosinase can influence quality. Myrosinase catalyses hydrolysis of glucosinolates to give glucose, sulphate, isothiocyanates, and oxazolidinethiones and other compounds. Some of these compounds act as catalyst poisons during hydrogenation of oil for margarine production. Therefore it is important to keep the glucosinolates intact by effectively inactivating myrosinase by proper conditioning.  1, record 4, English, - oxazolidinethione

Dans le canola ou le colza, l'enzyme qui peut affecter la qualité de l'huile est la myrosinase. Cet enzyme catalyse l'hydrolyse des glucosinolates, réaction qui donne du glucose, du sulfate, des isothiocyanates et des oxazolidinédiones et d'autres composés. Il est donc important d'inactiver la myrosinase au cours du conditionnement pour conserver l'intégrité des glucosinolates.  1, record 4, French, - oxazolidin%C3%A9dione
