Abstract(s)
Chemical composition of Hibiscus drinks (Koor and Vimto varieties, commercial and traditional, infusions
and syrups) (n = 8) was related to sensory evaluation and acceptance. Significant correlations between
chemical composition and sensory perception of drinks were found (i.e. anthocyanin content and Hibiscus
taste) (p < 0.05). Consumers (n = 160) evaluated drink acceptability on a 9-point verbal hedonic scale.
Three classes of behaviour were identified: (a) those who preferred syrup (43% of consumers); (b) those
who preferred infusion (36%); and (c) those who preferred all of the samples (21%). Acceptability of ‘syrup
likers’ was positively correlated to sweet taste, reducing sugar content and inversely correlated to acidic
taste and titratable acidity (p < 0.10). Acceptability of ‘infusion likers’ was positively correlated to the taste
of Hibiscus drink and anthocyanin content. The study showed that the distinctions between the acceptability
groups are very clear with respect to the chemical composition and rating of sensory attributes
