Cefodroxil monohydrate is formed by a processing which includes a) bringing an aqueous solution of cefadroxil monohydrate to a pH of between 7 to 9 with a suitable titrant; b) lowering the pH to a value of between 5 and 6.5 to obtain a suspension of cefadroxil monohydrate in crystal form; and c) isolating the cefadroxil monohydrate in crystal form from the suspension obtained in step b). The cefadroxil monohydrate thereby obtained exhibits a CIE b value of below 6, and advantageously a CIE b value of below 12 when stored at a temperature of 25 C. for at least 1 month.
