摘要: 在常温下,反应物L-抗坏血酸与苯甲酸按摩尔比为65反应,可得到产物L-抗坏血酸苯甲酸酯,产物为白色鳞片状结晶,产率为72.6%,L-抗坏血酸苯甲酸酯具有明显的抗氧化作用,添加L-抗坏血酸苯甲酸酯实验组的油脂过氧化值显著低于空白对照组。L-抗坏血酸苯甲酸酯还具有一定的抗菌作用,在2‰浓度下,可基本抑制大肠杆菌生长,与1‰苯甲酸的抗菌能力相当。这些实验表明,L-抗坏血酸苯甲酸酯具有抗菌、抗氧化的双重作用。本研究可为新型、多功能食品添加剂的开发提供依据。

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.
