Today, due to the high consumption of essential oils and perfumes and their side products such as health and cosmetic products, the use of synthetic chemical compounds in industries has increased significantly. Synthetic chemical compounds are compounds that are prepared in chemical laboratories. In many cases, synthetic materials perform better than natural products in terms of chemistry and smell, because unlike natural materials, their production does not depend on the weather conditions of nature. Therefore, the preparation of synthetic materials in industries can be synthesized from natural materials such as flowers and fruits. .
The root of the word perfume is derived from the Latin word parfum, and it means fleeting smell. Throughout history, perfumes have played an important role in human life and have always brought happiness, beauty and love. Ancient Egyptians always used different perfumes to perfume their homes, and they always made bathrooms and safes fragrant with perfume.
Modern perfumery is a combination of art, science and technology. The chemistry of perfumes is extremely complex and includes 5000 thousand different substances. Fragrance chemistry examines the physical and chemical properties of materials, including fragrance, volatility, strength and stability. These properties are directly related to their molecular structure. In the structure of each molecule, there are groups that give the molecule special physical and chemical properties, which are known as functional groups.
Classification of chemical substances based on these groups can be an important tool to identify aromatic substances for the essential oil industry. Of course, the effect of functional groups depends on their number and position in the molecule.
Since hundreds of substances with different functional groups are combined in essential oils, it is possible that some of them are activated under the influence of air, light, temperature and react with other substances. These chemical interactions can change the ingredients in the essential oil and lead to a change in their aroma and taste, of course, in some cases.
