Coffee is one of the most consumed beverages in the world, and this study aimed to evaluate the influence of different manufacturing materials of Koar® filter holders (acrylic, stainless steel, ceramic, and porcelain) on the physicochemical characteristics and antioxidant activity of coffee beverages. The results showed that despite having similar design features (such as outlet diameter, grooves, and angle), the material of each Koar filter significantly affected the extraction dynamics of coffee components, resulting in beverages with distinct physicochemical compositions and antioxidant activities. Through multivariate statistical analysis, similarities were identified between the filter materials and the parameters evaluated. In general, coffee extracts obtained from acrylic and ceramic filters exhibited higher values of total phenolics, ABTS antioxidant capacity, reducing sugars, total soluble solids, and extraction percentage. In addition, coffee drinks from stainless steel and porcelain filters presented higher values of total titratable acidity, electrical conductivity, DPPH antioxidant capacity, and caffeine content. Understanding the effects of different filter materials on coffee extraction can contribute to optimizing brewing methods and enhancing consumer satisfaction. These findings highlight the importance of careful selection of filter holder material to ensure different sensory profiles of coffee beverages, providing valuable information for the industry and coffee enthusiasts.
Key words: Beverage quality; coffee brewing; extraction dynamics; Koar®.
