starch turns into dextrine ⟨through baking⟩
assertsneutralsource: general-pg50759
turn much of the starch into dextrine
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'light and well browned in baking, so as to turn much of the starch into dextrine.' The passage explicitly asserts that starch turns into dextrine through the baking process, with no rewording or interpretation needed.
- qualifier_fidelity 0.90 pass — The claim is largely faithful to the passage. The quote appears verbatim: 'turn much of the starch into dextrine' is found in the passage discussing how biscuits are 'most digestible when light and well browned in baking, so as to turn much of the starch into dextrine.' The perspective, stance, and sentiment are all correct - the author asserts this neutrally. The time qualifiers (all null) are appropriate as the passage gives no temporal scope. The context 'through baking' accurately reflects the passage's restriction of this claim to the baking process. All qualifiers are faithful to the passage.
starch produces little change when boiled in pure water change
assertsneutralsource: general-pg50759
long boiling of starch in pure water produces little change upon it
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage's opening sentence: 'long boiling of starch in pure water produces little change upon it.' This is an exact match with the source material.
- 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 general knowledge without naming a specific source). The stance is correctly marked as 'asserts' - the passage states this as fact. The sentiment is neutral, appropriate for a scientific statement. The time qualifiers are correctly null since no specific temporal scope is given. The context is empty, which is appropriate as the passage provides none. The quote is verbatim from the passage and directly supports the claim.
starch becomes entirely converted into grape sugar when treated with sulphuric acid grape sugar
assertsneutralsource: general-pg50759
if a little sulphuric acid is added, the starch will take up more water and become entirely converted into grape sugar
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The exact quote provided matches the passage text, which explicitly states that when sulphuric acid is added to starch in water, 'the starch will take up more water and become entirely converted into grape sugar.'
- 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 'asserts' which matches the passage's matter-of-fact presentation. The sentiment is neutral, appropriate for a technical/scientific statement. The time qualifiers are all null, which is correct since the passage provides no temporal information about when this process occurs. The context is empty, which is appropriate as the passage does not restrict this claim to a specific sense or role. The quote is verbatim from the passage and directly supports the claim about starch conversion via sulphuric acid treatment.
grain is crushed and fermented starch
assertsneutralsource: general-pg50759
The grain is crushed and fermented to a degree, when the starch is washed out
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The text explicitly states 'The grain is crushed and fermented to a degree, when the starch is washed out,' which directly confirms that grain is crushed and fermented in the process of making laundry starch.
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to 'author' (the passage presents this as general informational content without attribution to a named source). The stance 'asserts' is appropriate as the passage states this as fact. The sentiment is neutral, matching the passage's objective, instructional tone. The time qualifiers are all null, which is correct as the passage provides no temporal information. The context is empty, which is appropriate as the passage does not restrict this to a particular sense or role. The quote is verbatim and accurately supports the claim about the grain being crushed and fermented.

starch is added to powdered sugar not for profit but to prevent caking
assertsneutralsource: sugar-pg73616
Starch is not introduced for the purpose of making a greater profit, but to prevent the powdered sugar from caking
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly supported by the passage. The exact quote provided matches the text verbatim: 'Starch is not introduced for the purpose of making a greater profit, but to prevent the powdered sugar from caking.' The passage explicitly states that starch is added to prevent caking, not for profit purposes.
- 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 the author's explanation). The stance is appropriately 'asserts' as the passage states this as fact. The sentiment is neutral, matching the informative tone. The time qualifiers are all null, which is correct since the passage provides no temporal scope. The context is empty, which is appropriate as the passage does not restrict the claim to a specific sense or role. The quote is verbatim from the passage and directly supports the claim about starch being added to prevent caking rather than for profit.
some manufacturers use starch in powdered sugar to prevent caking starch ⟨two to three per cent⟩
assertsneutralsource: sugar-pg73616
some manufacturers who buy coarse granulated sugar from the refiners for grinding purposes use starch to the extent of from two to three per cent
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The text explicitly says 'some manufacturers who buy coarse granulated sugar from the refiners for grinding purposes use starch to the extent of from two to three per cent' and later confirms 'Starch is not introduced for the purpose of making a greater profit, but to prevent the powdered sugar from caking.' The claim accurately reflects both the action and the stated purpose.
- qualifier_fidelity 0.90 pass — The claim is highly faithful to the passage. The viewpoint, stance, sentiment, time, and quote are all accurate. The quote is verbatim and supports the claim. The context specification of "two to three per cent" is appropriate and faithful to the passage. One minor note: the context field is typically used for semantic sense distinctions (e.g., coffee as plant vs. drink), whereas "two to three per cent" is more of a quantitative specification; however, this is not incorrect and does reflect information from the passage, so it does not constitute a material error in qualifier fidelity.

starch is extracted with ether
assertsneutralsource: coffee-pg28500
Extract 5 grams of the finely pulverized sample on a hardened filter with five successive portions (10 cc. each) of ether
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage. The opening sentence of section 17 explicitly describes extracting the sample with successive portions of ether, which is the standard method for removing starch from the pulverized sample.
- qualifier_fidelity 0.80 pass — The claim is mostly faithful to the passage. The quote is verbatim and accurately supports the predicate that starch is extracted with ether. The viewpoint 'author' is appropriate since the passage is instructional text without attribution to a named source. The stance 'asserts' and sentiment 'neutral' are faithful. The time qualifiers (all null) are correct as the passage provides no temporal information. However, the context is empty when it should specify this is a method/procedure context - the passage is a tentative analytical method for starch determination, not a general statement about starch properties. The context should reflect 'analytical method' or similar to be fully precise, though its absence is less critical than other qualifiers.
