Chlorogenic acid (CGA) is a natural antioxidant

and nowadays it has been used in medicine

food processing and cosmetic industry.However

to a certain extent its application is restricted because it is only soluble in water but is lipo-insoluble.In this research

liposoluble chlorogenic laurate(CGL) was synthesized by acylation with lauroyl chloride (LC) in the presence of triethylamine (TEA) in non-water phase.It was found that the optimized synthesis conditions were as follows: with dimethylformamide (DMF) as the dissolution agent and thinner

n CGA∶n LC∶n TEA＝1∶1∶1.5

temperature(35±1)℃ and reaction time 8 h.Under these conditions a light yellowish powder was obtained and the yield of CGL was 81.24 %.The structure of CGL was characterized by UV-Vis

IR

ESI-MS and H NMR. Theoretically

the method of quantum chemistry calculation was used to demonstrate the feasibility and rationality of molecular modification for CGA.Meanwhile

the result of the test of the use of CGL on Guangdong-type sausage showed that 0.05% of CGL could increase the antioxidant ability of the products.
