Sažetak
Since 19th century, a controversial discussion is going on about thujone, a characteristic component of the essential oil of the wormwood plant Artemisia absinthum L., Salvia officinalis and other, which are commonly used in production process of alcoholic beverages such as wormwood flavoured spirit or bitter liqueur. After consuming alcoholic beverages, thujone is considered to be responsible for possible mental disorder, including the symptoms of hallucinations, sleeplessness and convulsions. In order to define the stability of α-thujone and ß- thujone this research has been conducted by using Croatian traditional bitter liqueur „Pelinkovac“. The results showed that the portion of α-thujone and ß-thujone in Croatian traditional bitter liqueur „Pelinkovac“ decrease as product becomes more mature. Portion of α-thujone decrease from 24, 52-24, 53 mg/l a.a. to 15, 81-22, 09 mg/l a.a. after first year and to 14, 03-19, 97 mg/l a.a. after three years. Content of ß-thujone decrease from 24, 38-24, 39 mg/l a.a. to 15, 83- 21, 98 mg/l a.a. after first year and to 14, 13- 20, 03 mg/l a.a. after three years. More significant decrease has been recorded if samples were kept in oak barrels in comparison to decrease which happened when samples were kept in stainless steel barrels or commercial glass bottles.
