What You Need to Know
The syrup is heated to 120–140 °C, vaporizing volatile aromatics without caramelizing sugars, while simultaneously exposing it to 80–100 °C smoke for 30–60 min. Phenolic aldehydes such as guaiacol and syringol adsorb onto the syrup matrix, imparting a smoky aroma and boosting antioxidant activity by ~15 %.
