Abstract
In Cameroon’s expanding eneological sector, local producers are
responding to the rise of a middle-class consumer base with specific
sensory expectations. Despite comparable pricing (~1300 FCFA/L) and
similar packaging, commercial dry red wines show marked variability in
consumer acceptance. This study sought to characterize and identify
the physicochemical factors influencing consumer preferences
among three popular locally produced red wines. Hedonic sensory
and physicochemical evaluations were conducted. ANOVA, linear
regression, and principal component analysis (PCA) were strategically
applied to examine and interpret the results. Hedonic analysis revealed
that wine 654 was significantly (p<0.05) more appreciated (mean
score: 3.63 ± 0.94) than wines 886 and 587. Linear regression indicated
that in-mouth volume, odor, acidity, and in-mouth warmth were the
main sensory attributes driving overall liking. The most appreciated
wine, wine 654, exhibited a distinct chemical profile: lower pH (2.97 ±
0.02), higher total acidity (5.58 ± 0.01 g/L), lower alcohol content (12.29
± 0.09%), and greater color intensity (6.89 ± 0.02). It was also richer
in total phenolics (TPI: 30.20 ± 0.03 AU), anthocyanins (40.40 ± 2.32
mg/L), and amino acids (AA: 1.21 ± 0.07 g/L), and showed moderate
tannin (0.97 ± 0.01 g/L) and vitamin C levels (90.00 ± 10.00 mg/L).
Except for dry extract in two samples, all parameters complied with
OIV standards. Principal Component Analysis identified acidity, sugar,
alcohol, AA, total proteins, total SO2, and total phenolic compounds
as the main physicochemical markers of sensory quality, thus providing
avenues for optimizing wine quality to align with the specific palate of
Cameroonian consumers. To further advance this work, future research
will focus on detailed profiling of phenolic compounds, organic acids,
and volatile aromatic compounds contributing to the overall sensory
experience.
