Methods Illumination, temperature, ph, metal ions, oxidants, antioxidants, preservatives and sugar were studied on the stability of vitamin B 2 by UV visible spectrophotometry. Results Effect of light on vitamin B 2 was the biggest, with its 1-h loss rate of 40%; Mg 2+ could cause vitamin B 2 loss rate to 10% after 5 h, Fe 3 + and Cu 2 + could cause damage through react with vitamin B 2 and generate other substances; Vitamin C could cause about 13.8% loss of vitamin B 2 ; Common food additives, such as potassium sorbate, sodium benzoate, and oxidant hydrogen peroxide had the limited effect on vitamin B 2 ; Glucose could not cause the loss of vitamin B 2, and sugar could cause the loss of 20%. Conclusion The stability of vitamin B 2 is affected by many factors, among which the greatest impact is the light; some metal ions, vitamin C and sucrose also affect the stability of vitamin B 2.
