Antioxidant and sensory properties of glasswort added coffee

This study aimed to develop a functional coffee drink by adding the glasswort (Salicornia europaea L.) known to have excellent antioxidant activity. Glasswort extract was added to espresso, filter drip and cold brew coffee to evaluate antioxidant activity and sensory properties. As a result, the antioxidant activity was increased depending on the concentration of the glasswort in all types of coffee extracts. The sensory evaluation showed that the preference decreased due to the addition of the glasswort but in the milk coffee, the decrease in preference was not significant with the addition of the glasswort. Therefore, milk coffee with 0.2-0.3% of the glasswort added to espresso is seen as a possible functional coffee.
