Background: Hydrodistillation is a current method to extract plant essential oils which is time consuming. It has been proposed that use of microwaves instead of direct heat could decrease the time of distillation. In this study, the effect of microwaves on chemical profile and antioxidant activity of Zatariam multiflora and Syzygium aromaticum essential oils in comparison to current hydrodisti...
The essential oil (EO) from dried ground powder leaves and stems of Thymua danesis was extracted using hydrodistillation (HD), ohmic extraction (OE), ultrasound-assisted HD and ultrasound-assisted OE methods. Then, the antioxidant, antimicrobial, and sensory properties of the EO were investigated both in vitro and in food systems. Thyme EO extracted by ultrasound-assisted HD method had promisin...

Flavonoids belong to the extensive group of polyphenol compounds. They can function as antioxidants and antibacterials by denaturing bacterial cell proteins damaging cells. One source essential oils is lime peel, which often discarded goes unused. The distillation method utilizes microwaves, offering an alternative conventional techniques resulting in enhanced effectiveness efficiency. Microwav...
