1. A process for enhancing the food value of protein-rich seeds, said seeds being selected from at least one of the following proteaginous plant species seeds: fava bean (Vicia fava L.), pea (Pisum sativum L.), white lupin (Lupinus albus L.), blue lupin (Lupinus angustifolius L) and yellow lupin (Lupinus luteus L),
comprising the following successive steps:
a) providing seeds of at least one of the above mentioned plant species, with the proviso that they have a protein content, and/or a starch content, and/or a fat content, of a value greater than or equal to that indicated in the table below, where DM signifies “Dry Matter”:

b) pressurizing the seeds from step a) for 10 seconds to 2 minutes at a minimum pressure of 10 bars at a temperature of 80° C. to 160° C.; or b1) dry heating the seeds via dryer, toaster, and/or thermostated screw, for 15 minutes to 2 hours at a temperature of 80° C. to 150° C.
