Abstract

On peut obtenir de la méthionine dépourvue de matières colorantes à partir d'une solution aqueuse de sels alcalins de méthionine préparée par hydrolyse de la 5-( beta -méthylmercaptoéthyl)hydantoïne à l'aide d'une base forte, en décolorant la solution à l'aide d'un composé de soufre réducteur, puis en recueillant la méthionine sous forme de cristaux incolores.
