Study on the stability of Anthocyanin energy drink.According to high performance liquid chromatography(HPLC) to determine the Anthocyanin content after different processing conditions.Anthocyanin is very sensitive to temperature and light,The stability of Anthocyanin is not significant effect to K~+,Ca~2+,Mg~2+,Zn~2+and Cu~2+,which is also different effects to different sterilization way,ultra high temperature short time sterilization as to it's affect the least.Anthocyanin energy drink can be conserved at room temperature for preventing light conditions,and can be appropriately added with some metal ions to increase its nutritional value;Ultra high temperature short time sterilization can be adopted to ensures that the nutrient composition is without loss.
