caffeol, a complex which is water-soluble
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly describes caffeol as "a complex which is water-soluble" when distinguishing it from true essential oils.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage itself makes this assertion). The stance of 'asserts' is appropriate as the passage presents this as a factual statement, not a dispute. The sentiment is neutral, matching the objective, technical tone of the passage. The time qualifiers are correctly null since the passage provides no temporal scope. The context is empty as appropriate since the passage does not restrict this statement to a particular sense or period. The quote 'caffeol, a complex which is water-soluble' appears verbatim in the passage and directly supports the claim.
upon extraction of ground roasted coffee with water, the caffeol shows a preferential solubility in water
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact phrase 'the caffeol shows a preferential solubility in water' appears in the final sentence, and the context of 'upon extraction of ground roasted coffee with water' is also explicitly mentioned in the same sentence.
- 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 information without attribution to a named source). The stance is properly marked as 'asserts' - the passage states this as fact. The sentiment is neutral, matching the technical/scientific tone. The time is correctly null since the passage provides no temporal scope. The context accurately reflects the specific condition mentioned ('upon extraction of ground roasted coffee'). The quote is verbatim and directly supports the claim.
is dissolved out from the oil, going into the brew
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'upon extraction of ground roasted coffee with water, the caffeol shows a preferential solubility in water, and is dissolved out from the oil, going into the brew.' The subject, predicate, and object are all explicitly supported by the text.
- qualifier_fidelity 0.90 pass — The claim is highly faithful to the passage. The quote is verbatim and accurately supports the predicate. All qualifiers are correct: viewpoint is properly attributed to 'author' (no named source), stance is correctly 'asserts', sentiment is neutral, time is appropriately null, and context accurately reflects 'water extraction' as stated in the passage. The only minor consideration is that the passage uses 'is dissolved out from the oil, going into the brew' which slightly emphasizes the movement from oil to brew, but the claim's predicate 'dissolves into' accurately captures this relationship without introducing any unfaithful qualifier.
