How to Distinguish Methionine True or Not ?

                    How to Distinguish Methionine True or Not ?

DL Methionine is an essential amino acids that plays an important role in feed field. However, there is lots of fakes in methionine market. So, I would like to share some tips for your reference:

1.  Burn, do not leave residue, there is an smell of burnt feathers;

2.  Touch, there is a special smell methionine (hydroxysteroid special smell hydroxyl group) with true methionine;  a little sweet when taste, touched smothly not rough .

False methionine smell bad, such as ammonia or Aroma smell , feel rough, not creamy.

3. Dissolve: Take methionine around 1 gram , add distilled water 50 ml, stir gently, shaking, standing, solution clearly and no precipitation with real methionine; If not, it is false.
