Abstract
A method for preparing cut and frozen vegetables including the step of washing the vegetables in order to eliminate any residues of soil or other substances and materials that may have accumulated during picking. In a subsequent step, it is necessary to subject the vegetables to a mechanical treatment in order to isolate their edible part. One then proceeds by cutting the vegetables into granules with sizes comprised between 30 mm3 and 60 mm3 by using a cutting device. At this point, one proceeds by immersing the granules in water for a predefined limited time. At a later time, one proceeds by scalding, with jets of hot water, the granules and air drying them.
