HIGHLIGHTS
  • Phenolic acids quench gliadin fluorescence by complexes formation
  • Phenolic acids are bond reversibly and exhibit moderate affinities to protein
  • Caffeic, ferulic and sinapic acids interact with gliadin to form 1:1 complexes
  • Hydrogen bonding play major role in the phenolic acids-gliadin complexation

ABSTRACT
Due to the health benefits attributed to the consumption of phenolic acids, these compounds can be used as natural pro-health food or beverages ingredients. To improve polyphenols stability during food processing and storage, they could be encapsulated in colloidal systems e.g. via complexation with proteins. The process of gliadin protein and phenolic acids complexation was investigated with application of fluorescence spectroscopy. Strong fluorescence quenching of gliadin was observed as a result of phenolic addition and two types of quenching mechanism were determined: dynamic (for coumaric acid) and static (for caffeic, ferulic and sinapic acid). This result indicates that coumaric acid, unlike to other analysed acids, does not form complexes with gliadin. The binding constant for caffeic, ferulic and sinapic acid – gliadin interaction is between 0.4 and 8.7 x 103 M-1. These three acids induced changes in protein conformation and tryptophan microenvironment. The calculated number of binding sites suggests that caffeic, ferulic and sinapic acids interact with gliadin to form 1:1 complexes. Analysis of thermodynamic parameters suggested that van der Waals and/or hydrogen bonding interactions play major role in the interactions between caffeic, ferulic as well as sinapic acid and gliadin.
