at the same time as the caffein is extracted, the volatile aromatic and flavoring constituents of the coffee are removed also
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The quoted text explicitly says that when caffein is extracted from roasted coffee, 'the volatile aromatic and flavoring constituents of the coffee are removed also,' which perfectly supports the subject-predicate-object relationship asserted in the claim.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (passage presents this as descriptive fact). The stance is appropriately 'asserts' (not disputed). The sentiment 'negative' matches the passage's framing of this as 'the great objection' and 'virtually insurmountable obstacle.' The time qualifiers are correctly null since the passage provides no temporal scope. The context is appropriately empty as the passage doesn't restrict this to a particular sense. The quote appears verbatim and directly supports the claim about removal of aromatic and flavoring constituents during caffein extraction from roasted coffee.
- extraction of caffein from roasted coffee was abandoned as method for decaffeinated coffee production
forced the abandonment of this mode of attack
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states that 'This virtually insurmountable obstacle forced the abandonment of this mode of attack,' referring to the extraction of caffein from roasted coffee as a method for developing decaffeinated coffee. The passage clearly indicates this approach was abandoned due to the removal of volatile aromatic and flavoring constituents.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual narrative without named sources). The stance 'asserts' matches the passage's declarative framing. The sentiment is appropriately neutral - the passage describes this objectively as a technical problem. The time qualifiers are correctly null since the passage provides no specific dates or temporal scope. The context is appropriately empty as the passage does not restrict the claim to a particular sense or period beyond the general historical narrative. The quote 'forced the abandonment of this mode of attack' appears verbatim and accurately supports the claim about abandoning the roasted coffee extraction method.
