The product is irritating to the eyes and respiratory system. Wear suitable protective equipment when using and carrying. In case of contact with eyes, immediately consult a doctor for treatment after flushing with plenty of water.
Disodium Succinate occurs in the form of crystalline granular or powder; it ranges from colorless to white. It is odorless, and is of fresh taste. Its taste threshold is 0.03%. It is stable in the air, and is highly soluble in water. It exists in two forms, that is, hexahydrous disodium succinate, and anhydrous disodium succinate. The former is in the form of crystalline particles, and the latter is in the form of crystalline powder. It varies from colorless to white. It is odorless, and is of fresh taste. Its taste threshold is 0.03%. It is stable in the air, and is highly soluble in water.
it is mainly used in food industry serving as flavor enhancer, additive, pharmaceutical intermediates, flavoring agent, acidulant,and buffering agent. It is wisely used for making ham, sausage, flavoring liquid and so on. At present, some manufactures of monosodium gltamate have been popularizing the add of succinic acid sodium in the production process.
