Abstract
D,L-methionine may include, based on the total weight of the D,L-methionine, from 15 to less than 50 wt.-% of the D,L-methionine with a particle size from more than 0 to less 150 micrometers, from 50 to less than 90 wt.-% of the D,L-methionine with a particle size from more than 0 to less 300 micrometers, and from 30 to less than 80 wt.-% of the D,L-methionine with a particle size in the range between 63 and 300 micrometers. The D,L-methionine may have a bulk density of at least 710 kg/m3.
