Southeast Asian cinnamon contains functional compounds and essential oils that act as natural and beneficial antioxidants. This research developed and evaluated for Microwave-Assisted Hydrodistillation (MAHD) to combine simultaneous extraction of phenolic compounds and distillation of essential oil using a green solvent - Natural Deep Eutectic Solvent: Citric Acid-Sucrose (NADES-CAS). This study aimed to evaluate the performance of NADES-CAS in collecting functional compounds (phenolic and proanthocyanidins) and essential oils using MAHD. The MAHD was conducted using NADES-CAS with a molar ratio of 1:1 in concentrations of 1% under microwave power of 640, 720, and 800 W. The performance was evaluated using Peleg's equation as a kinetic approach. The microwaves increased the value of EC, TDS, and solvent temperature but decreased the density and viscosity, supporting MAHD. Peleg's kinetic model describes an increase in microwave power increase the rate constant (B0) and capacity constant (Ce ). The B0 values of phenolic and proanthocyanidin compounds were in the range of 0.0264-0.0397 mg/mL.min and 0.0388-0.1117mg/mL.min, respectively. Meanwhile, the Ce value of these compounds were in the range of 0.5349-0.6607 mg/mL and 0.5529-0.9439 mg/mL, respectively. The model accurately predicting the profiles of each compound concentrations during MAHD. The combination of MAHD and NADES successfully distilled essential oils from cinnamon powder with significant components such as Cinnamaldehyde and minor components such as caryophyllene, benzaldehyde, and pinene. This innovation is potential to be applied to accelerate the simultaneous extraction of phenolic compounds and distillation of essential oils from cinnamon.
