Features and Properties
Succinic acid is distributed widely through the natural world, where it is contained in bivalves, fossils, algae, lichen, bacteria, and so on. It was discovered in 1550 by the German chemist Georgius Agricola, who was the first to purify it from amber by dry distillation (succinite).Succinic acid is useful, non-toxic, stable and harmless to the human body. It is generated in a citric acid cycle (succinic acid dehydrate enzyme) and a succinic acid-glycine cycle through the process of metabolism, and eventually becomes energy. Succinic acid is industrially produced by the hydrogenation of maleic anhydride.The succinic acid manufactured by Nippon Shokubai was launched in 1950. Since then, in addition to its use as a food additive, our succinic acid has been used in a wide range of fields including biodegradable resins, bath additives, plating chemicals, and photo developing agents.
