Abstract

This article presents experimental data from the analysis of pullulan grafted with ferulic acid with low grafting rates via enzymatic catalysis. These data come from preliminary tests as described in the related research article “Antioxidant functionalization of pullulan with ferulic acid using enzymatic catalysis”. The Pull-FA derivatives’ grafting rates, measured by the Folin-Ciocalteu assay, are determined, as well as their UV signatures. These data supplement the main article and highlight the impact of the ferulic acid grafting on pullulan, even at low rates (between 3.1 and 9.7 mg.g−1). The various analyses carried out show the self-associative character of the derivatives even at low grafting rates. Finally, the products all exhibit antioxidant properties (analyzed using a DPPH• reagent). In summary, for Pull-FA-T40% having the highest FA content of 9.7 mg.g−1, the critical aggregation concentration was found at 0.13 g.L−1, and the radical scavenging reached 60%. The data may help for a better understanding of the behavior of naturally functionalized polysaccharides with phenolic compounds, as well as for those that are enzymatically or chemically modified.
