Properties and stability

Odorless, no sour taste. It has a special shellfish flavor. Stable in air. When the hexahydrate reaches 120°C, it loses crystal water and becomes anhydrous.

Storage method

should be sealed and stored.

Synthesis method

Neutralize succinic acid and sodium hydroxide, dry and pulverize at 120°C.


Disodium succinate has good solubility and strong permeability. It is mainly used as a flavoring agent. It not only has a seasoning effect, but also can alleviate the irritation of other seasonings and improve the seasoning effect. Our country stipulates that it can be used for seasonings, and the maximum usage amount is 200g/kg. Flavoring agent; sour agent; buffering agent. Mainly used for ham, sausages, aquatic products, seasoning liquids, etc. The general dosage is 0.01% ~ 0.05%. When used as a condiment, powdered anhydrous material is generally used to speed up dissolution.
