Easy to decompose metamorphoism in alkaline solution. Ph 3.5 to 100oC high temperature resistantm, acid and alkali easy failure is greater than 5. Light and heat titer decreased. Reason should be placed in the window, cool, preservation,
storage should be placed in the window, cool, preservation, storage shoulds not be long. In acidic, solution is stable, in the alkaline solution is not stable, susceptible to oxidation and heat damage. Reducing substances sulfite, such as sulfur dioxide can make vitamin B1 inactivation.
Widely distributed in the skeletal muscle, cardiac muscle, liver, kidney and brain tissue, has a half-life of 9 ~ 10 days. Vitamin B1 mainly exists in the outside of the seed and germs, such as rice bran and bran is rich in content, content is extremely rich in yeast. Lean meat, Chinese
