Sensorial profile, content, and antioxidant activity in coffee beverages prepared by direct contact methods

Abstract

Direct content coffee preparation methods may be used as alternative ways to obtain coffee beverages with varied cup profiles. In this investigation the antioxidant metabolites, antioxidant activity, and cup profiles were determined for coffee drinks prepared using five different direct contact methods. The method that registered greatest antioxidant retention was Ibrik, followed by French press, and Toddy. Antioxidant capacity was proportional to antioxidant component retention in the preparations made. It is recommended that coffee be prepared via the Ibrik, French press, and Toddy methods for high acceptance levels, as well as for retention of bioactive components with antioxidant properties and abilities.
