Abstract

The present paper has studied the formation of acetals in acid catalyzed caramelization processes in ethanol medium, showed an increase in hydrophobic properties of acetalized products, confirmed calculations of lipo-hydro partition coefficient values. It is possible, that the hydrophilic OH-groups are also bonded by the solvent molecules into ethers. Based on the data obtained, it can be concluded that it is possible to hydrophobize caramel compositions when they are synthesized in acidic ethanolic media, which allow to develop technological compositions based on simple carbohydrates in the future.
