Raw material preparation: First, the raw materials necessary for aroma production are prepared. The type of raw materials may vary depending on which aroma is to be obtained. For example, lemon peels can be used for lemon aroma, and vanilla pods can be used for vanilla aroma.
Extraction: Raw materials are extracted, usually using a solvent (liquid). This helps extract the essence from the raw materials, aiding in obtaining the desired aroma. The most commonly used solvents for extraction are organic solvents such as ethanol, methanol, or hexane.
Concentration: The extraction process yields a solution obtained from the raw materials. This solution is then concentrated. This makes the aroma substance denser and allows for easier storage. Concentration can be achieved by heating the solution under a vacuum.
Mixing: The concentrated aroma substance is mixed with carrier agents (usually water). This gives the aroma substance a more homogeneous structure and makes it easier to use.
Filtration: The mixture undergoes a filtration process. This removes any remaining residue in the product and ensures a cleaner and purer final product.
Storage: The prepared aroma is stored under appropriate conditions. These conditions may vary depending on the type and properties of the aroma substance.
Industrial aroma production is used in many areas, particularly in industries such as food and cosmetics. Industrially prepared aromas can be offered in powder, liquid, or gelled forms and can be available in various flavors and scents.
