Abstract
Microwave hydrodiffusion and gravity (MHG) extraction of Ulex europaeus was proposed for the production of extracts. The extraction time and yield and the antioxidant and sensorial properties of the extracts were significantly affected by the irradiation power. MHG treatment at 100Â W during 76Â min provided optimum yields and the extracts showed the highest reducing power and antiradical activity. The extraction time could be reduced in relationship to that needed with steam distillation (153Â min) to reach comparable extraction yields and retaining the antioxidant properties. The flower extracts from the two tested technologies showed similar color (colorless) and olfactometric characteristics (floral and ripe fruity aroma).
