Abstract

The study investigated the effects of reducing fat content from 33 (full-fat, FF) to 22 (reduced-fat, RF) or 16 (half-fat, HF) % on the concentrations of total and individual free amino acids (FAA) and free fatty acids (FFA) in Cheddar-style cheeses with 1.9 (full-salt, FS), 1.2 (reduced-salt, RS) or 0.9 (half-salt, HS) % NaCl over a 270d maturation period at 8°C. Both FAA and FFA increased continuously during ripening, from ∼1200 and 230mg/kg at 30d to 5500 and 1593mg/kg, respectively, in FFFS at 270d. Reducing fat content resulted in higher concentrations of FAA (e.g., from 5500mg/kg in FFFS to 6400mg/kg in HFFS at 270d) and lower levels of FFA (e.g., from 1593mg/kg in FFFS to 1140mg/kg in the HFFS cheese at 270d). Reducing salt content from 1.9 to 1.2 or 0.9 % resulted in a significant decrease in FAA in the FF cheese, from 5500mg/kg in FFFS to 4000mg/kg in FFHS at 270d. Salt content did not significantly affect the concentration of FAA in RF or HF cheeses, or the concentration of total or individual FFA in the FF, RF or HF cheeses.

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.
