    Abstract: PROBLEM TO BE SOLVED: To produce a methionine-containing molded product causing a small amount of dust, excellent in fluidity and useful for feeds, or the like, by providing the molded product with a prescribed bulk density, a prescribed particle spectrum and a prescribed methionine content. SOLUTION: This molded product has 300-850 kg/m3 bulk density, 63-5,000 μm particle spectrum and 85-95 mass % methionine content in a predominant amount based on the total mass. Furthermore, the methionine-containing molded product is preferably produced by separating water from an aqueous methionine suspension to 8-40 mass % based on the total mass, washing the resultant solid with water, preferably a mother liquor taken out of the production process, adding an organic binder such as methyl cellulose and/or an inorganic binder such as potassium (hydrogen)carbonate, a silicic salt filler and further a compound effective for a feed such as lysine, feeding the resultant mixture to a shaping process, extruding and drying the mixture.

    Abstract: PROBLEM TO BE SOLVED: To provide a practical and economical method for hydrolyzing methionyl-methionine in a suitable ratio, by avoiding undesirable side reaction and decomposition of an end product. SOLUTION: An improved method for producing methionine comprises rapidly converting the methionyl-methionine which is a by-product into the methionine which is the product through hydrolysis reaction. The method is conducted at a high temperature (200°C to 280°C) in a short residence time (20 sec to 200 sec). The method is suitable for increasing a final yield of the methionine which is the desired end product through processes for producing the methionine. An extremely high space-time yield is realized due to the high temperature, so that the method ensures an economical efficiency. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract translation: 要解决的问题：通过避免不期望的副反应和最终产物的分解，以适当的比例提供用于水解甲硫氨酰 - 甲硫氨酸的实用和经济的方法。 解决方案：一种改进的产生甲硫氨酸的方法包括将作为副产物的甲硫氨酰 - 甲硫氨酸迅速转化为通过水解反应产物的甲硫氨酸。 该方法在短时间（20秒至200秒）的高温（200℃至280℃）下进行。 该方法适用于通过生产甲硫氨酸的方法提高作为所需最终产物的甲硫氨酸的最终产率。 由于温度高，实现了极高的空时收益，从而确保了经济效益。 版权所有（C）2005，JPO＆NCIPI

    Abstract: Un procedimiento para producir metionina, que comprende las etapas de: a) añadir al menos un compuesto seleccionado de carbonato de potasio, bicarbonato de potasio e hidróxido de potasio a una disolución que contiene 5- (β-metilmercaptoetil)hidantoina para hidrolizar 5-(β- metilmercaptoetil)hidantoina para obtener una disolución que contiene metionina, b) saturar la disolución que contiene metionina con dióxido de carbono para precipitar la metionina, y separar la metionina precipitada al tiempo que se deja un primer filtrado, c) dividir el primer filtrado en una primera parte y en una segunda parte, devolviendo la primera parte a la etapa (a), y transferir la segunda parte a la etapa (d), en donde la primera parte del primer filtrado puede estar ausente, d) calentar la segunda parte del primer filtrado hasta una temperatura de 210ºC a 280ºC durante un tiempo de permanencia entre 20 y 200 segundos y a una presión por encima de la presión de vapor del agua a la temperatura empleada, y saturar el filtrado térmicamente tratado con dióxido de carbono para precipitar la metionina y bicarbonato de potasio, y separar la metionina y el bicarbonato de potasio precipitados al tiempo que se deja un segundo filtrado, y e) descargar el segundo filtrado o devolverlo a la etapa (a).
