Abstract
The present invention is directed to an improved process for producing methionine in which the by-product methionyl-methionine is quickly converted to the product methionine by a hydrolysis reaction. The process is performed at high temperatures (200° C. to 280° C.) and short residence times (20 s to 200 s) and results in an improved yield of end product methionine.
