Extraction of hops pelletized (Humulus lupulus) with subcritical CO and hydrodistillation: Chemical composition identification, kinetic model, and evaluation of antioxidant and antimicrobial activity.

Hop essential oil and hop extract using carbon dioxide (CO) are products with high added value because they have bioactive and sensory properties. In this context, the objective of this study was to obtain and characterize essential oil and extracts from pelleted hops of El Dorado, Polaris, Hallertau Blanc and Callista varieties using hydrodistillation and subcritical CO extraction methods. Extraction yield ranged from 0.
