The invention relates to a method of treating grains, in particular cereal grains, pseudocereal grains or grain legumes, as well as to grains treated with this method. The method comprises the following steps: a) soaking the grains in an aqueous medium, wherein the grains are least temporarily soaked in an aqueous medium comprising at least one reactive oxygen species b) draining the aqueous medium from the grains c) tempering the grains and allowing them to at least partially germinate d) hydrothermally treating the grains for a time in the range from 0.25 h to 4 h at a temperature in the range from 60° C. to 100° C. and at a relative humidity in the range from 60% to 100%.
