Claim 1

THE PROCESS OF TREATING THE OIL EXTRACTION RESIDUE MEAL OF MUSTARD SEED, FROM WHICH A VEGETABLE OIL HAS BEEN EXTRACTED BY MEANS OF A SOLVENT, COMPRISING CONTROLLING THE TEMPERATURE OF THE SEEDS AND KEEPING IT FROM BEING RAISED DURING THE EXTRACTION PROCESS, TO PREVENT DECOMPOSITION OF THE ENZYME MYROSIN NATURALLY OCCURRING IN THE SEEDS, MIXING THE MUSTARD OIL RESIDUE MEAL WITH WATER IN AN AMOUNT SUFFICIENT TO PRODUCE A RATIO OF WATER TO OIL EXTRACTION MEAL IN THE RESULTING MIXTURE OF BETWEEN 8:1 AND 6:1 PARTS BY WEIGHT, BRINGING THE MIXTURE TO A TEMPERATURE RANGING BETWEEN 45*-55*C., MAINTAINING THE MIXTURE AT SAID TEMPERATURE FOR A TIME SUFFICIENT TO PRODUCE HYDROLYSIS OF THE SINIGRIN NATURALLY OCCURRING WITHIN THE SEEDS, HEATING THE MIXTURE THEREAFTER TO THE BOILING POINT AND ADMITTING LIVE STEAM TO THE MIXTURE TO PRODUCE DISTILLATION OF ALLYL ISOTHIOCYANATE BEING ONE OF THE PRODUCTS OF THE HYDROLYSIS, SEPARATING THE ALLYL ISOTHIOCYANATE FROM WATER AND PURIFYING THE SAME AND SCREENING, PRESSING AND DRYING THE REMAINDER OF THE MIXTURE WHICH HAS NOT BEEN DISTILLED OFF, THUS RECOVERING SIMULTANEOUSLY ALLYL ISOTHIOCYANATE AND A PROTEINACEOUS CONCENTRATE.
