  • Product Details


DL-Methionine CAS 59-51-8 is white crystal or light grey crystal or powder with special smell. The density is 0.6g/cm³ and the melting point is 281ºC. It can be soluble in water,low-concentration acid & alkali solution.


DL-Methionine is biological protein synthesis skeleton amino acids. DL-Methionine is the necessary growth factors in livestock animal. It can also regulate animal's metabolism. It is already widely used in feed, medicine, food and cosmetics, etc. In the feed industry, the maximum dosage is DL-Methionine. It is used to strengthen feed nutritional. If you add 1kg DL-Methionine in feed, and its nutritional value correspond to 50kg fish powder. DL-Methionine addition was 0.5%-0.2% in the feed.

Application

DL-Methionine can regulate animal’s metabolism. It is already widely used in feed, medicine, food and cosmetics, etc.

In the feed industry, the maximum dosage is DL-Methionine. It is used to strengthen feed nutritional. If you add 
1kg DL-Methionine in feed, and its nutritional value correspond to 50kg fish powder. DL-Methionine addition was 
0.5%—0.2% in the feed. 
In the medicine area, DL-Methionine is the major element in aminophenol transfusion and compound amino acids.
And also can used in synthetic medicinal vitamin. DL-Methionine has anti-fatty liver effects can be used to produce liver drug.
In the food area, DL-Methionine is used for food’s amino acids and health food processing. And also used as
nutrition supplement. DL-Methionine can also cause de—methylation.

Packing
