The present invention concerns a granulated 
powder containing at least one vegetable 
protein and at least one vegetable 
fiber, characterized in that it has a 
laser volume 
mean diameter D4,3 of between 10 μm and 500 μm, preferably between 50 μm and 350 μm, and even more preferably between 70 μm and 250 μm, and a 
dry matter content, determined after stoving at 130° C. for 2 hours, of greater than 80%, preferably greater than 85%, and even more preferably greater than 90%. The present invention also concerns a process for manufacturing this granulated 
powder as well as its use in various industrial field, and more particularly in the food-
processing field, where it is used as a functional agent such as an emulsifying, overrun, stabilizing, thickening and / or gelling agent, in particular for totally or partially replacing certain
