Abstract: The synthesis method,anti-microbial and antioxidative properties of L-ascorbyl benzoate were studied.The mole ratio of reactant L-ascorbic acid to benzoic acid was 6:5.The reaction temperature was between 25 to 30℃.The end product was white flake crystal.Product yield rate is 72.6%.L-ascorbic benzoate showed significant antioxidative property.The peroxide value of L-ascorbyl benzoate added oil sample was obviously lower than that of control.L-ascorbyl benzoate also showed anti-microbial property.The growth of  Escherichia coli was inhibited by  2% of L-ascorbyl benzoate.The anti-microbial effect of  2% L-ascorbyl benzoate was equivalent to that of  1% benzoic acid.The results indicated that L-ascorbyl benzoate have anti-microbial and antioxidative dual function.This research may provide reference for the development of novel,multi-functional additives.
