Whole grain bread and potatoes are vitamin B₁ sources of considerable dietary importance. Animal tissues rich in vitamin B₁ are liver, kidney, brain and heart. Aqueous solutions of thiamine hydrochloride are unstable in the presence of alkalis and substances with alkaline reactions, atmospheric oxygen, metal ions and UV light. Moreover, the solutions are affected by reducing and oxidizing agents, especially in the neutral and alkaline ranges.
