摘要：
The potentially wide application of Phenolic acids (PAs) in industries was severely limited by their inadequate solubility and stability in polar/non-polar media. To overcome these limits, studies on the enzymatic esterification of PAs with glycerol were carried out to reach a yield of 95% of phenolic acid glycerols (PAGs) under the following reaction conditions: 1:150 molar ratio of PAs to glycerol; 25% of Lipozyme 435 relative to the weight of total substrates; 80degree celsius, 500 rpm, 86.7 kPa and 10 h. Three resulting PAGs including caffeoyl glycerol (CG), feruloyl glycerol (FG), and p-hydroxycinnamoyl glycerol (p-HCG) were confirmed by MS, 1H NMR and 13C NMR. Among them, CG showed a comparative free radical scavenging ability to CA, indicating its potential use as a water-soluble antioxidant alternative to CA for food and cosmetic applications.
