Problems solved by technology

Because terpenes are unsaturated hydrocarbons, they are sensitive to heat and light, and are rapidly oxidized in the air. Therefore, such compounds are easily oxidized and enzymatically produced by processing factors such as long-term distillation and improper storage to produce carvone, carveol and other off-flavors, thereby reducing the quality of essential oils and shortening their shelf life
