Enzymatic lipophilization enhances phenolic acids, creating amphiphilic molecules for oil-based applications. This process improves their solubility and expands their use in various industries.

Area of Science:

  • Biochemistry
  • Organic Chemistry
  • Industrial Biotechnology

Background:

  • Phenolic acids have valuable biological properties but limited solubility in oil-based products.
  • Lipophilization, or esterification, modifies molecules to improve their hydrophilic/lipophilic balance.
  • Enzymatic methods offer a sustainable route for lipophilization.

Purpose of the Study:

  • To review advances in the enzymatic lipophilization of phenolic acids.
  • To explore the creation of novel amphiphilic molecules from phenolic acids.
  • To highlight potential industrial applications of these modified compounds.

Main Methods:

  • Esterification of phenolic acids with fatty alcohols using enzymes.
  • Utilizing various enzymatic systems, including free or immobilized enzymes (lipase, feruloyl esterase, tannase).
