Summary The suitability of rapeseed as a protein supplement for human consumption and in animal feed is limited because of toxicity problems caused by the presence of antinutritional factors such as glucosinolates. There are a number of procedures for removing or decreasing the quantity of glucosinolates and their hydrolysis products but all these processes have major drawbacks such as protein loss, incomplete inactivation, cost and a lack of economic viability. In this study, Instantaneous Controlled Pressure Drop (Détente Instantanée Contrôlée DIC ® ) treatment was evaluated on rapeseed meal. The results demonstrate the efficiency of DIC ® as a new process for the detoxification of rapeseed. Indeed, glucosinolate content decreased by 40% after 1 min of treatment and by 98% after a 7‐min treatment, demonstrating the efficiency of DIC ® as a new process for rapeseed treatment.
