Thiamine Nitrate, also known as thiamine nitrate and vitamin B1 nitrate, is a chemical substance, white to yellowish crystalline or crystalline powder. Used in rice, noodles, pastries, soy sauce, etc., but also used in medicine.
Properties White to yellowish crystalline or crystalline powder, odorless or slightly odorous, melting point 196~200ºC (decomposition), non-hygroscopic. Slightly soluble in water (its solubility is less than thiamine hydrochloride, 1g is about 35mL in water), insoluble in ethanol and chloroform. It is stable in air, more stable in neutral solutions than in acidic solutions (pH=4.0), and more stable than thiamine hydrochloride.
Application field
As a nutritional supplement, it is less water-soluble than hydrochloride and more stable to alkali, so it is more stable than hydrochloride when used for food fortification. Can be used in rice, noodles, pastries, soy sauce, etc. It is also used in medicine.
