Green Engineering for Aroma Stabilization

Aromas represent highly valuable substances that are widely applied in the food, pharmaceutical, and cosmetic industries.

Although aromas are high in demand, their instability represents one of the major factors that significantly hinder their efficient application.

Environmentally-friendly and effective production of aromas has been achieved through the development and implementation of the supercritical carbon dioxide extraction (SCCO2) technology.

However, stabilization of aromas still represents an issue and many technologies that are being developed still fail to provide a clean, cost-effective process of stabilization.This project addresses these challenges.

The goal of the project is to establish an efficient, green, and semi-continual procedure that combines the processes of production and stabilization of aromas by coupling the green technology of SCCO2 with the new generation of deep eutectic solvents (DESs).

DESs are green solvents that possess high solubilization and absorption capacities and their advantages of being biodegradable, inexpensive, and adjustable make them excellent candidates for stabilization of aromas.

Integration of the processes of production and preservation provides an innovative, stable, and safe product to be used in various industries and secures maximal exploitation of natural resources.

Implementation of project solutions leads to the reduction in energy consumption, decrease in environmental damage caused by toxic solvents, and successfully meets the demands of the market for safer and green products.

The project results will also represent new scientific findings in the area of application of green technologies and set the foundations for new research and projects for the scientific community.
