Abstract

The effect of coffee bean quality (specialty and regular) and brewing method (cold and hot) on the sensory profile and physicochemical characteristics of coffee beverages was studied. Cold brew was prepared by immersion and hot brew coffee by French Press. Total dissolved solids (TDS), titratable acidity (TA), caffeine, trigonelline, 4 and 5- caffeoylquinic acids were quantified by instrumental methods, volatile compounds by GC–MS, and the coffee flavor was through quantitative sensory evaluation. Coffee beverages were more differentiated by brewing method than by the coffee bean quality used in the preparation. Cold brew coffees were mainly associated with volatile 2-methyl-butanal, 5-methyl furfural, and dihydro-2-methyl- 3 (2H) -furanone. Hot brew coffee beverages were identified with some specific furans and 2-methoxy-4-vinylphenol. No significant differences were found in TDS, caffeine, trigonelline, 4 and 5 caffeoylquinic acids. A higher TA was observed in hot coffee beverages than in cold brew coffees. Regular bean quality promoted undesirable sensory attributes in both cold and hot brew beverages. However, these attributes were perceived in higher intensity in hot brew coffee beverages. Thus, differences in brewing methods affect the extraction of the chemical compounds present in different coffee bean quality, translating into variations in the sensory profile.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
