Chemical composition, antioxidant capacity, and thermal behavior of Satureja hortensis essential oil

Abstract Satureja hortensis is one of the representative plants from the Lamiaceae family, and its essential oil has been used in various applicative fields, from the food industry to aromatherapy. The changes that occur in heated samples at different temperatures (160, 175, 190 ºC) over different p...
