| Abstract: | In the paper,the effect of temperature ,time and pH values on the stability of Vc was studied. The result showed that Vc was stable in the condition of netural of faintly acid solution, but unstable in air,heat, basic solution. There exists significantly negative correlation between different storage time and the content of ascorbic acid. |
