Though thiamine is found naturally in foods, Vitamin B1 mononitrate is not found. Thiamine mononitrate is mostly synthesized by removing a chloride ion from thiamin hydrochloride and mixing with nitric acid. Thiamine hydrochloride is hygroscopic (water-absorbing) whereas the Thiamine mononitrate has almost no hygroscopic properties. Because of this property, Vitamin B1 mononitrate is the more stable form of the vitamin in fortified flours and cereals.
