The present invention relates to an improved process for the preparation of methionine, which rapidly converts by-product methionyl-methionine to the product methionine by a hydrolysis reaction. The invention is carried out at high temperatures (200 ° C. to 280 ° C.) and short residence times (20 seconds to 200 seconds). The method is suitable for increasing the final yield of methionine, the desired final product during the preparation of methionine.n n n Due to the high temperature a very high space-time yield can be achieved, thereby ensuring the economic efficiency of the process described herein.n n n n Method for preparing methionine, methionyl-methionine, hydrolysis |
