description An object of the present invention to provide a method for producing methionine with consideration given to the environment. The production method of the present invention comprises a removal step of blowing an inert gas into a liquid containing 5-(2-methylmercaptoethyl)hydantoin and thereby diffusing ammonia remaining in the liquid to obtain an emission gas containing the ammonia, and a recovery step of bringing the emission gas into contact with a washing liquid to recover ammonia contained in the emission gas.
