摘要：
The present invention relates to propionic acid-comprising compositions in solid and essentially pure form comprising at least one compound according to formula (I)(Mn+)(H+)x(CH3CH2C(O)O−)(n+x) (I),whereMn+ is an n-valent alkali metal cation or alkaline earth metal cation, n being equal to 1 or 2 andx is a number in the range from 0.25 to 5with the proviso that x is not in the range from 0.75 to 1.75 when Mn+ is potassium a method for producing such propionic acid-comprising compositions and also the use of such compositions as silage additive, preservative, acidifier, food supplement, feedstuff or feedstuff additive for animal feed.
