anethole, is one of the main compounds of essential oils found in most plants and flowers. Like other essential oils, it is used as a sweetener additive to foods. Essential oil compounds and derivatives derived from synthetic means are also used in perfumery and cosmetics as well as sweetening additives in the food industry.

Anetol is found in the essential oils of anise, fennel and many other plants. It is named after the dill, which is found in very small amounts. The anetol compound is most commonly used in chewing gums and anise alcohol products (raki) to provide flavor. In addition, liquorice is used in confectionery, honey, nuts and some spices. In the cleaning sector, anethole is also used to give a nice smell to detergents, deodorants and soap. Anethole is insoluble or only slightly soluble in water, but easily soluble in alcohol and oil.

Anise ether oil, which plays an essential role in the aroma of raki, consists of two main compounds: anethole, which is solid at normal temperature, and estragol, which is a liquid. Anise seeds are used in the production of raki. However, the amount used varies depending on the type of raki and the quality of the anise (usually between 6-10 percent).

Trans anethole and estragol compounds found in anise ether oil are effective in raki quality according to their amounts. Close to 90 of anise ether oil is anethole compound. It is similar to spice, it has a characteristic anise smell and is a very sweet liquid. Estragol is an isomer of the anetol compound. The estragol compound, which is liquid at room temperature, smells like anise, but does not taste like anise.

In authorized laboratories, within the scope of chemical food analysis, rakı and the analysis of trans anethole, estragol and similar volatile components present in similar drinks. In these studies, standards and test methods published by domestic and foreign organizations are followed.
