What specific compounds are efficiently trapped by paper filters during brewing?
Answer
Diterpenes (natural coffee oils)
Paper filtering agents are highly effective at intercepting certain components present in the coffee bean during extraction, most notably the natural coffee oils, which are chemically classified as diterpenes. By trapping these oils and extremely fine particles, the resulting brew exhibits a visually clean appearance and a significantly lighter texture on the palate, contributing directly to the clarity that characterizes paper-filtered coffee.
