Effect of Extraction Methods on Aroma Profile, Antioxidant Activity and Sensory Acceptability of Specialty Coffee Brews

Barbora Lapčíková,
Lubomír Lapčík,
Petr Barták
et al.

Abstract: Specialty coffees from various geographical origins were processed using different extraction methods. Four extraction techniques were employed: cold brew (CB), espresso (ES), French press (FR), and aeropress (AE). The potential health benefits of coffee brews were linked to their antioxidant activity, as determined by the DPPH assay, and total polyphenol content (TPC) measured through the Folin–Ciocalteu reducing-capacity assay. The Columbia (C) espresso coffee type (omni-roasting) exhibited the highest antio… Show more

“…This analysis unveiled noteworthy disparities in their reaction to drought, which were attributed to alterations in the proteins associated with photosynthesis and the metabolism of oxidative stress [ 55 ]. The antioxidant activity of coffee is mainly due to the presence of polyphenols, flavonoids, and other bioactive substances [ 56 ]. Examples include caffeine, gallic acid, and proanthocyanidins, which contribute to antioxidant efficacies [ 57 ].…”
