N2 - Green cardamom (Elettaria cardamomum) is an outspread spice native to Asia, which is well appreciated for its sensory characteristics, delicate aroma, and unique taste. Currently, the main cardamom extracts are essential oils (EOs), and regarding current market tendencies, this market is in high growth. For this reason, technologies such as the instant controlled pressure drop (DIC) have been applied to reach higher yields and better quality of EO. Then, this study explores the impact of DIC as a pretreatment before hydrodistillation (HD) on the EO yield and their antioxidant activity. Obtained results showed that the coupling of DIC-HD increased the yield of essential oil and also had a positive impact on their antioxidant capacity. The EO yield of DIC-HD (140◦C and 30 s) was 4.43% vs. 2.52% for control; the AOX of DIC-HD (165◦C and 30 s) was 86% inhibition vs. 57.02% for control, and the TEAC of DIC-HD (140◦C and 30 s) was 1.44 uMTE/g EO vs. 13.66 uMTE/g EO.
