How to distinguish DMPT and DMT

1. Different chemical names
The chemical name of DMT is Dimethylthetin, Sulfobetaine;
DMPT is Dimethylpropionathetin;

They are not the same compound or product at all.

2. Different production methods

DMT is synthesized by the reaction of dimethyl sulfide and chloroacetic acid under the action of a catalyst;
DMPT is obtained by reacting dimethyl sulfide with 3-bromopropionic acid (or 3-chloropropionic acid).

3. Different appearance and odor

DMPT is a white powdery crystal, while DMT is a white needle shaped crystal.
The fishy odor of DMPT is smaller than that of DMT, which has an unpleasant odor.

4. DMPT has a better function than DMT, and DMPT is more expensive.

5. Different forms in nature

DMPT is not only widely exist in seaweed, but also in wild fish and shrimp, and is widely exist in nature; DMT, does not exist in nature and is a purely chemically synthesized substance.

6. Different flavors of aquaculture products
DMPT is a characteristic substance that distinguishes marine fish from freshwater fish, It’s one of the flavor substances that make seafood have a seafood flavor (rather than a freshwater fish flavor).
The meat quality of fish and shrimp fed with DMPT is similar to that of natural wild fish and shrimp, while DMT cannot achieve such an effect.

7. Residual

DMPT is a naturally occurring substance in the body of aquatic animals, which does not have residual and can be used for a long time.
