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