Provided is a production method for dehydrated vegetable powder that does not contain additives and that can be quickly reconstituted (reconstituted in about 10 seconds to one minute) to a grated state by adding cold water, and from which the original freshly grated taste and texture of vegetables can be reproduced. The production method for dehydrated vegetable powder has the following: in this order, a step for dehydrating raw vegetables that uses a method other than vacuum freeze drying and a step for vacuum freeze drying and a vegetable pulverizing step that comes between the step for dehydrating raw vegetables that uses a method other than vacuum freeze drying and the step for vacuum freeze drying, or follows the step for vacuum freeze drying. The production method for dehydrated vegetable powder is characterized by the following: (1) the step for dehydrating raw vegetables that uses a method other than vacuum freeze drying is for dehydrating so that vegetable weight is 10-95wt%, taking raw vegetables as a reference (2) the step for vacuum freeze drying is for dehydrating so that the water content of vegetables is no more than 5wt%, taking raw vegetables as a reference and (3) the step for pulverizing is for pulverizing so that the median size of dehydrated vegetable powder is no more than 600μm.La présente invention concerne un procédé de fabrication de poudre de légumes déshydratés qui ne contient pas dadditifs et qui peut être rapidement reconstituée (dans un délai denviron 10 secondes à une minute) dans un état râpé en ajoutant de leau froide, et qui permet de reproduire le goût et la texture des légumes dorigine fraîchement râpés. Le procédé de fabrication de poudre de légumes déshydratés est le suivant : dans cet ordre, une étape de déshydrogénation de légumes crus qui utilise un procédé autre que la lyophilisation sous vide et une étape de lyophilisation sous vide et une étape de pulvérisation de légumes qui intervient entre létape de déshydratation de
