The invention relates to a method for producing a soy milk or a soy-based drink. The method according to the invention comprises the following steps: a) soaking and b) grinding the soy beans to give a paste, c) separating the soy paste into soy milk and okara, carrying out steps (a) and (b) and preferably (c) at temperatures of from 0 DEG C to 40 DEG C, which temperatures are suitable for obtaining native proteins, and then deodorizing the soy milk by means of an evaporation method in order to reduce the typical bean taste. The invention provides a method which allows a product to be obtained that has, in terms of organoleptic quality, an improved yield with respect to the protein content of the soy milk and a reduced bean taste. The invention also relates to a method for producing a soy milk according to which soy beans are ground by extruder technology for obtaining native proteins and for improving the taste of the soy milk.
