Characteristics of "Succinic Acid"
"Succinic Acid" is distributed widely through the natural world, where it is contained in bivalves, fossils, seaweed, lichen, bacteria and so on. It was discovered in the year 1550 when Dr.Agricola with Germany distilled amber. "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 hydrogenation of Maleic Anhydride. Succinic Acid of NIPPON SHOKUBAI has not only been used as food additives but also biodegradable polymers, bath additives, plating agents, photochemicals and so on.
