E: extract; HP: hop pellets; SFE-CO₂: supercritical carbon dioxide extraction; TEAC: Trolox equivalent antioxidant capacity; TE: Trolox equivalents; ORAC: oxygen radical scavenging capacity. Different superscript letters in the same row indicate significant differences (one-way ANOVA and Tukey‘s test p < 0.05).
